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

                                                            needs    user

recovery group  active   current or master server          service  vdisks  remarks

--------------  -------  --------------------------------  -------  ------  -------

BB01L           yes      server01.gpfs.net                 yes           3

BB01R           yes      server02.gpfs.net                 no            3

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  pdisk         priority  FRU (type)       location

--------------  ------------  --------  ---------------  --------

BB01L           e2s11             1.15  00W1240          Enclosure 2 Drive 11

BB01L           e3s01             1.15  00W1240          Enclosure 3 Drive 1

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:   - Remove carrier.

mmvdisk:   - Replace disk in location SX32901810-11 with type '00W1240'.

mmvdisk:   - Reinsert carrier.

mmvdisk:   - Issue the following command:

mmvdisk:

mmvdisk:   mmvdisk pdisk replace --recovery-group BB01L --pdisk 'e2s11'

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.

Removing the disk physically

1. Press the blue touchpoint to unlock the latching handle, as shown in this figure.
