I took a look at it's support page as a courtesy anyway, but didn't see an entry. The folks on the workstation board may be able to provide better information. I don't work with Windows 11 or the Precision series of products, but it looks like it may still have an iDRAC interface.

Some configured disks have been removed from your system or are no longer accessible. Check your cables and ensure all disks. Check the cable connections and fix issues if any. Degraded state of virtual disks. A redundant virtual disk is in a degraded state when one or more physical disks have failed or are inaccessible. For example, if a RAID 1 virtual disk consists of two physical disks and one of them fails or become inaccessible, the virtual disk become degraded.
To recover a virtual disk from a degraded state, you must replace the failed physical disk and rebuild it. Once the rebuilding process is complete, the virtual disk state changes from degraded to optimal. Memory errors can corrupt cached data, so the controllers are designed to detect and attempt to recover from the memory errors. Single-bit memory errors can be handled by the controller and do not disrupt normal operation.
A notification is sent if the number of single-bit errors exceeds a threshold value. Multi-bit errors are more serious as they result in corrupted data and data loss. The following are the actions that occur in the case of multi-bit errors:.
The controller generates a warning message to the system console to indicate that the cache was discarded and generates an event. The controller preserves the dirty cache from a virtual disk if the virtual disk becomes offline or is deleted because of missing physical disks. This preserved dirty cache is called pinned cache and is preserved until you import the virtual disk or discard the cache.
A foreign configuration is a RAID configuration that already exists on a replacement physical disk that you install in a system. A secured foreign configuration is a RAID configuration that was created under a different security key. Supply the correct passphrase to import the secured foreign configuration.
If you have lost or forgotten the passphrase, the secured foreign disks remain locked inaccessible until the appropriate passphrase is entered or if they are instant secure erased. A virtual disk can be either secured or unsecured depending on how it was configured when created.
In order to create a secured virtual disk, the controller must have a security key present and must contain SEDs only. You can create an unsecured virtual disk even if there is a security key. For steps on how to create an unsecured virtual disk, see Creating virtual disks.
A security key is used to lock or unlock access to a security-enabled component. This key is not utilized in the actual encryption of data. If a security key is present, both secured and unsecured virtual disks may exist. To delete the security key, you must have a previously established security key present on the controller and there cannot be any configured secured disks.
If there are configured secured disks, remove or delete them. Instant Secure Erase is the process of securely erasing all data permanently on an encryption-capable physical disk and resetting the security attributes. It is used in a couple of scenarios such as deleting a foreign configuration in the event of a forgotten or lost passphrase or unlocking a disk that had been previously locked.
Instant Secure Erase can be executed only on encryption-capable disks as long as the disks are not hot spares and are not configured part of a virtual disk. Ensure that the conditions are met and see Instant Secure Erase. The device is displayed in Device Manager but has a yellow bang exclamation mark. Reinstall the driver.
For more information on reinstalling drivers, see Driver installation. PERC card not seen in device manager.
Physical disk issues. Physical disk in failed state. One of the physical disks in the disk array is in the failed state. Update the PERC cards to the latest firmware available on dell.
Unable to rebuild a fault tolerant virtual disk. Cannot rebuild a fault tolerant virtual disk. For more information, see the alert log for virtual disks. The replacement disk is too small or not compatible with the virtual disk. Replace the failed disk with a compatible good physical disk with equal or greater capacity. Fatal error or data corruption reported. Fatal error s or data corruption s are reported when accessing virtual disks.
Physical disk displayed as blocked. One or more physical disks is displayed as Blocked and cannot be configured. Multiple disks become inaccessible. Rebuilding the physical disks after multiple disks become simultaneously inaccessible. Multiple physical disk errors in a single array typically indicate a failure in cabling or connection and could involve the loss of data.
You can recover the virtual disk after multiple physical disks become simultaneously inaccessible. Perform the following steps to recover the virtual disk:. Turn off the system, check cable connections, and reseat physical disks. If the virtual disk is redundant and transitioned to Degraded state before going Offline, a rebuild operation starts automatically after the configuration is imported.
If the virtual disk has gone directly to the Offline state due to a cable pull or power loss situation, the virtual disk is imported in its Optimal state without a rebuild occurring. For information on. Issue: Rebuilding a physical disk that is in a failed state.
Corrective Action: If you have configured hot spares, the PERC card automatically tries to use one of the hot spares to rebuild a physical disk that is in a failed state. Manual rebuild is necessary if no hot spares with enough capacity to rebuild the failed physical disks are available. You must insert a physical disk with enough storage in the subsystem before rebuilding the physical disk. For information. A virtual disk fails during rebuild while using a global hot spare.
The global hot spare reverts to Hotspare state and the virtual disk is in Failed state. Virtual disk fails during rebuild using a dedicated hot spare. A virtual disk fails during rebuild while using a dedicated hot spare. The dedicated hot spare reverts to Ready state and the virtual disk goes to Failed.
Physical disk fails during reconstruction on redundant virtual disk. A physical disk fails during a reconstruction process on a redundant virtual disk that has a hot spare. Virtual disk fails rebuild using a dedicated hot spare. The dedicated hot spare is in Ready state and the virtual disk is in Failed state. Physical disk takes a long time to rebuild. A physical disk takes longer to rebuild when under high stress. You cannot add a second virtual disk to a disk group while the virtual disk in that disk group is undergoing a rebuild.
The firmware does not allow you to create a virtual disk using the free space available in a disk group if a physical disk in a virtual disk group is undergoing a rebuild operation. SMART errors. SMART monitors the internal performance of all motors, heads, and physical disk electronics and detects predictable physical disk failures. NOTE: If a hot spare is present, the rebuild starts with the hot spare after the disk is forced offline.
NOTE: The Replace Member operation allows you to copy data from a source physical disk of a virtual disk to a target physical disk that is not a. Use Replace Member or set up a global hot spare to replace the disk automatically. Replace the affected physical disk with a new physical disk of equal or higher capacity. If the source data is available from other disks in the virtual disk, the rebuild begins automatically on the target disk, using the data from the other disks. Target disk fails.
If the target disk fails, the Replace Member operation aborts. General disk fails. If the target disk fails and the Replace Member operation aborts but the source data is still available, then the Replace Member operation continues as Replace Member. Linux operating system errors. Virtual disk policy is assumed as write-through error message. The controller firmware manages the virtual disk cache settings on a per controller and a per virtual disk basis, so the firmware does not respond to this command.
SDB is the device node for a virtual disk. This value changes for each virtual disk. Except for this message, there is no effect of this behavior on normal operation. This is a known issue. An unsupported command is entered through the user application. The error message does not affect the feature functionality. This action is not supported. The LED on the physical disk carrier indicates the state of each physical disk.
The activity LED is active whenever a disk is being accessed while the status LED indicates when a disk is being spun up, is rebuilding, or is in a fault state. One or more boot driver s have reported issues. This message might indicate that the cables are not connected, the disks might be missing, or the UEFI driver might require configuration changes.
Check if the cables are connected properly, or replace missing hard drives, if any and then restart the system. Press any key to load the driver health manager to display the configurations. The Driver Health Manager displays the driver s , which requires configuration. RAID is a group of independent physical disks that provides high performance by increasing the number of disks used for saving and accessing data.
The physical disk group appears either as a single storage unit or multiple logical units to the host system. Data loss caused by a physical disk failure can be recovered by rebuilding missing data from the remaining physical disks containing data or parity. RAID 1 is good for small databases or other applications that require small capacity and complete data redundancy.
RAID 6 uses block-level striping with two parity blocks distributed across all member disks. RAID 6 provides protection against double disk failures, and failures while a single disk is rebuilding. If you are using only one array, deploying RAID 6 is more effective than deploying a hot spare disk. It provides high data throughput and complete data redundancy. RAID 50 requires at least six disks. RAID 60 requires at least eight disks. Disk striping allows you to write data across multiple physical disks instead of just one physical disk.
Disk striping involves partitioning each physical disk storage space in stripes of the following sizes: 64 KB, The stripes are interleaved in a repeated sequential manner. The part of the stripe on a single physical disk is called a stripe element. For example, in a four-disk system using only disk striping used in RAID 0 , segment 1 is written to disk 1, segment 2 is written to disk 2, and so on.
Disk striping enhances performance because multiple physical disks are accessed simultaneously, but disk striping does not provide data redundancy. With mirroring used in RAID 1 , data written to one disk is simultaneously written to another disk. If one disk fails, the contents of the other disk can be used to run the system and rebuild the failed physical disk.
The primary advantage of disk mirroring is that it provides complete data redundancy. Both disks contain the same data at all times. Either of the physical disks can act as the operational physical disk. Disk mirroring provides complete redundancy, but is an expensive option because each physical disk in the system must be duplicated. NOTE: Mirrored physical disks improve read performance by read load balance. Parity data is redundant data that is generated to provide fault tolerance within certain RAID levels.
In the event of a disk failure, the parity data can be used by the controller to regenerate user data. Parity data is present for RAID 5, 6, 50, and The parity data is distributed across all the physical disks in the system.
If a single physical disk fails, it can be rebuilt from the parity and the data on the remaining physical disks. RAID level 5 combines distributed parity with disk striping.
Parity provides redundancy for one physical disk failure without duplicating the contents of the entire physical disks. RAID 6 combines dual distributed parity with disk striping. This level of parity allows for two disk failures without duplicating the contents of entire physical disks. NOTE: Parity is distributed across multiple physical disks in the disk group. NOTE: Parity is distributed across all disks in the array.

Physical disk power management Physical disk power management is a power-saving feature of the PERC 9 series cards. There are four power-saving modes:. Spin down is enabled only for unconfigured and hot spare disks.
Spin down is enabled for configured, unconfigured, and hot spare disks. Customized Power Savings All power savings features are customizable. You can specify a Quality of Service window during which the configured disks are excluded from spin-down.
Full initialization Performing a full initialization on a virtual disk overwrites all blocks and destroys any data that previously existed on the virtual disk. Fast initialization A fast initialization on a virtual disk overwrites the first and last 8 MB of the virtual disk, clearing any boot records or partition information.
Background initialization Background Initialization BGI is an automated process that writes the parity or mirror data on newly created virtual disks. Consistency checks Consistency Check CC is a background operation that verifies and corrects the mirror or parity data for fault tolerant virtual disks.
Disk roaming Disk roaming is moving the physical disks from one cable connection or backplane slot to another on the same controller. Using disk roaming Perform the following steps to use disk roaming: 1. Disconnect power cables from the system. Turn on the system. Table 1. Turn off the system. Virtual disk write cache policies The write cache policy of a virtual disk determines how the controller handles writes to the virtual disk.
The write cache policies are: Write-Back The controller sends a data transfer completion signal to the host when the controller cache has received all the data in a transaction. Conditions under which write-back is employed Write-Back caching is used under all conditions in which the battery is present and in good condition.
Conditions under which forced write-back with no battery is employed CAUTION: It is recommended that you use a power backup system when forcing Write-Back to ensure there is no loss of data if the system suddenly loses power.
When Forced Write-Back mode is selected, the virtual disk is in Write-Back mode even if the battery is not present. Virtual disk read cache policies The read policy of a virtual disk determines how the controller handles reads to that virtual disk. The read policies are: Read Ahead Allows the controller to read sequentially ahead of requested data and to store the additional data in cache memory, anticipating that the data is required soon.
Table 2. Automatic replace member with predicted failure A Replace Member operation can occur when there is a SMART predictive failure reporting on a physical disk in a virtual disk. Patrol Read The Patrol Read feature is designed as a preventative measure to ensure physical disk health and data integrity.
The following is an overview of Patrol Read behavior:. Physical disk failure detection Failed physical disks are detected and rebuilds automatically start to new disks that are inserted into the same slot. Using replace member and revertible hot spares The Replace Member functionality allows a previously commissioned hot spare to revert to a usable hot spare. If the new disk is not placed in the same slot, a manual Replace Member operation can be used to revert a previously commissioned hot spare.
Once the operation completes, performance returns to normal. Controller cache preservation The controller is capable of preserving its cache in the event of a system power outage or improper system shutdown.
Recovering cache data If a system power loss or improper system shutdown has occurred: 1. Restore the system power. Boot the system. Battery Transparent Learn Cycle A transparent learn cycle is a periodic operation that calculates the charge that is remaining in the battery to ensure there is sufficient energy.

Luc23 This person is a verified professional. William Oct 13, at UTC. David J - Sorry about that, usually it works pretty well. Get the message This is not a supported Dell Server. Nothing fancy. Any more ideas please? John White This person is a verified professional. All works fine! Thank you! It has been a while since I worked on a RAID setup on a Dell server and your article walked me through the process quickly and quite easily.
I appreciate the help. Thanks a lot for your step-by-step guide, it was really helpful, as I am not a sysadmin person. Dear Ramesh Natarajan, Great Article! What is the NEXT step? How do we utilize the new Logical drive to extend our current storage? This is scary from a device management perspective. Thanks a ton. You helped get my Dell PowerEdge up and running. Can any one help me? I would like to know how to recover data in case for failed raid card or server crash. Let me know the details which will help me in case of server crash.
This is very very nice article with screen shot. Excellent Article, it was very useful for me Thank very much!!! Thank you so much for this post. The above was clear and worked first time. I had found the utility but nowehere does it say anything about F Thank you, but I have an issue with reassigning the drive letters after doing this proceedure. I have added the new drives and I can change the drive letters on them.
Will I be able to follow the same general idea as this article? I have 1TB in my computer currently and purchased another TB that I want to use as a mirror to back up data.
Someone mentioned disk format. In that case A should mean logical volume 0 disk 1. I am confused about it and the role of logical volume in RAID configuration. I came morning at server room and i heard alert sound peeeb peeb, i look to the server DELL PowerEdge there is orange led at one of HDD and the other flashed, and the server is working and its on windows. Please could you help me what is happened after finishing reconstruction.
At first thank you for the great tutorial. However no boot drives could be detected by the BIOS. In the system they were 5 scsi drives and one ide drive. I had to switch from Raid 5 to Raid 0 to be able to configure one only one scsi drive as a logical drive and install Now how can add the 4 other scsi drives to the array without altering my boot drive.
Thanks for you help. Sorry I meant how do I configure the ide drive as a back up and eventually to boot from in case the scsi fails. My server was shipped with a singal hdd. The Hard drives are shown in Raid config, but are written unuaseable. Please advice how to set up the raid? Could i be missing a step? I have a Dell PowerEdge with a Raid 1 2 scsci hdd of 73gb.
Can someone provide me with the steps to replace a fail hard drive on a PowerEdge with Perc Raid i think. I have a server PE today give me this error Error E07F0 processor 1 iErr the same for Processor 2 I restart the server and after this the server is not working more I move the hard drives to other identical server the server recognize all the Hard drive I have 4 HD gb on raid 5 and 2 HD gbon raid 1 but on the new server only recognize 2 HD on Raid1 and the other 4 as READY and the virtual drives is correct Can I delete the raid 1 configuration and recreate the correct raid configuration with Riad 5 and Raid 1?
Is there a solution to my problem? LD0 is raid 1, consist of 2 hdd. LD1 has 3 hdd, and 1 hdd is hot spare. After completed your mentioned steps, how do I make those logical drives recognized by bios. My case was when I began install windows , it failed to see drives. So I could not install the os. I have a problem where SLOT 3 on the 6 slot cage. When there is a drive in slot 3 it lights amber. Move the hard drive and it goes green. Is there a way to tell the controller that the drive that was in slot 3 is now in slot 4?
That way it will see the drive and the raid will work. There is alot more to the story and yes there is another drive not working in the raid. I need this drive from slot 3 to work so I can get the data off the raid. Any help would be appreciated. My plan was to simply copy the files from Server A to Server B over the network, then physically swap, on a one for one basis, the drives from B to A.
Server A has roles installed so that I would like to avoid reconfiguring on B. The former would seem to making this impossible, while if the later it seems to me that it should work.
