RGdisplay
This is the RAID Group display command. Use this command to display all RAID Groups and their statuses.
Note
If rgdisplay shows a RAID Group is OFFLINE, then data recovery methods should be initiated; skip this
section and go directly to the Section,
Recovering from Failed Drives on page 46.
If rgdisplay shows a RAID Group is DEGRADED, then it is important to replace the failed drive as soon as
possible. Rmstatus shows the status of each of the member drives. If a member is FAULTED or UNAVAILABLE,
it should be replaced. To match the displayed member to the physical drive, you can use sesidentify, which is the
preferred method, or blockdevidentify, if there is no SES capability.
Rmstatus
Next, use rmstatus, the RAID Member status CLI command, to show information for each member of the RAID Group
in question.
SESIdentify DRIVE (only valid if enclosure supports SES)
The drive FAULT LED should already be blinking. Use this CLI command to also blink the Identify LED for the drive. The
ID from the blockdevscan command must be used, and not the member ID shown in the rmstatus command. Match the
S/N of the FAULTED drive (9SF076NJ) from rmstatus to the blockdevscan drive IDs, and use that number to select the
correct drive to blink.
