Impending Physical Disk Failure (Medium Data Availability Risk)

What Caused the Problem?

A physical disk is reporting internal errors that could cause the physical disk to fail. If this physical disk fails, the virtual disks in the disk group will become degraded. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution: Risk of Data Loss. If a Virtual Disk - Hot Spare in Use problem is also displayed in the Summary area, always fix the Impending Physical Disk Failure first. Fixing the Virtual Disk - Hot Spare in Use failure before fixing the Physical Disk Failure may result in data loss.

Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching the components without using a proper ground may damage the equipment.

Important Notes

• The affected virtual disks are RAID 1/10, 3, 5, or 6. If the physical disk fails, you may lose redundancy. If additional physical disks fail in the same disk group, you may lose data. You should correct this problem as soon as possible.
• Because the physical disk has not failed, its fault indicator light will not be turned on.
• Make sure the replacement physical disk has a capacity equal to or greater than the physical disk you will remove.
• You can replace the physical disk while the virtual disks associated with the affected physical disk are receiving I/O.

Recovery Steps

1	Do one of the following: You can manually fail, remove, and replace the physical disk now. To do this, continue with step 2. OR You can take no further action and wait for the affected physical disk to fail. You can then complete the Recovery Steps to fix the problem when it is reported. You need to do nothing more in this procedure.
2	Check the status of the virtual disks associated with the affected physical disk. To determine the associated virtual disks, highlight the affected physical disk in the Physical View of the Array Management Window and select View >> Associated Elements. All virtual disks in the Logical View of the Array Management Window should be Optimal   before continuing with this procedure. If any virtual disks in the disk group currently show Operation in Progress , wait for all virtual disks to change to Optimal before continuing. If the virtual disks change from Operation in Progress to any status other than Optimal, click the Recheck button to rerun the Recovery Guru and fix the failures reported.
3	Highlight the affected physical disk in the Physical View of the Array Management Window and select Advanced >> Recovery >> Fail Physical Disk. The associated virtual disks become Degraded .
4	Remove the failed physical disk (its fault indicator light should be on).
5	Wait 30 seconds, then insert the new physical disk. Its fault indicator light may be lit for a short time (one minute or less).
6	Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.
