8. If the drive firmware is not at the latest level, issue the following command from one of the canisters

to update the drive firmware:

# mmchfirmware --type drive

a. After the

mmchfirmware

command completes, verify that the drive firmware levels are correct by

issuing the following command again:

# mmlsfirmware --type drive

Example

[ess3ka ~]# date; mmlsfirmware --type drive

b. If some drives failed to update to the current level, rerun the following command to update the

drives to the current level:

# mmchfirmware --type drive

9. Issue the following command against the affected recovery group. This command adds the new

capacity and begins rebalancing data onto the new disks.

# mmvdisk recoverygroup resize --recovery-group ESS 3000 recoverygroup

Example

[ess3ka ~]# mmvdisk recoverygroup resize --recovery-group ess3k_mySN

mmvdisk: Obtaining pdisk information for recovery group 'ess3k_mySN'.
