How to Troubleshoot LUN Failure Caused by Disk Logical Errors?

Publication Date:  2012-07-18 Views:  59 Downloads:  0
Issue Description
On a deployment site, a new D200 disk enclosure cannot be properly connected to the storage array due to a rate problem. Part of LUNs fail due to the disk logical errors in the storage array. The status of certain disks is physically normal but logically faulty on the management software interface, and relevant LUNs are in the offline state.
Alarm Information
None
Handling Process
View the faulty disk IDs (these disks are physically normal but logically faulty) and LUN IDs on the Web page. Enter the debug mode and run the revive rg command to view faulty RGs. Restore all faulty disks online under relevant RGs. After all offline disks become online, restore relevant LUNs online. After that, all disks and LUNs are restored to normal.
Root Cause
As the D200 disk enclosure is improperly connected to the storage array, logical errors occur on part of disks.
Suggestions
None
