Issue Description
Two hard disks on the VTL3500 are red on and the alarm buzzer is generated.
Alarm Information
None
Handling Process
If one disk is the hot spare disk and the other one is the member disk of a RAID group:
Step 1  Change the logical status of the two hard disks from unconfiged bad to unconfiged good.
Step 2  During RAID group configuration, import configuration information. Then, the original hot spare disk becomes a hot spare disk again and the original member disk starts reconstruction. After the reconstruction, the degraded RAID group goes back to normal
Root Cause
The abnormal system status leads to a logical disk abnormity but not to a physical disk abnormity.
Suggestions
If indicators of hard disks are red on and the RAID group is in the abnormal state, consider recovering logical status of the faulty disk through reconstruction first. If the reconstruction does not work, you can check whether the hard disk itself is faulty.
