If one or more pdisks in the recovery group is marked for replacement, the following command reports
it with a yes in the "needs service" column:
mmvdisk recoverygroup list
In the following example, the BB01L recovery group needs service:
# mmvdisk recoverygroup list
recovery group
--------------
BB01L
BB01R
This happens when the number of failed pdisks in one of the recovery group's declustered arrays
reaches or exceeds the replacement threshold for the declustered array.
Pdisks that have reached the threshold for replacement are listed with the following command:
mmvdisk pdisk list --replace
# mmvdisk pdisk list --recovery-group all --replace
recovery group
--------------
BB01L
BB01L
mmvdisk: A lower priority value means a higher need for replacement.
Preparing disks for replacement
1. Prepare each of the pdisk name entries for replacement with the following command:
mmvdisk pdisk replace –-prepare –-recovery-group <rg name> --pdisk <pdisk name>
To prepare pdisk e2s11 of recovery group BB01L for replacement, run the following command:
# mmvdisk pdisk replace --prepare --recovery-group BB01L --pdisk e2s11
mmvdisk: Suspending pdisk e2s11 of RG BB01L in location SX32901810-11.
mmvdisk: Location SX32901810-11 is Enclosure 2 Drive 11.
mmvdisk: Carrier released.
mmvdisk:
mmvdisk:

The drive associated with the pdisk name in the previous command should now have flashing amber
fault LED to indicate it is safe to remove this drive.
