c. If canister A is currently designated as a quorum node, move the quorum to a different node.
i) To determine which nodes are quorum nodes, issue the following command:
# mmlscluster
ii) To evaluate quorum status, issue the following command:
# mmgetstate -s
iii) If necessary, to designate a different node to be a quorum node, issue the following command:
# mmchnode –quorum -N node not in this enclosure’s nodeclass
iv) If necessary, to remove a quorum node from canister A, issue the following command:
# mmchnode –noquorum -N canister A
2. Unmount file systems that are mounted on canister A. (Customer task)
Unmount GPFS file systems from canister A.
# mmumount fs1 -N canister A
or you can unmount all file systems at a time from canister A:
# mmumount all -N canister A
Example:
[root@ess3k5a]# mmumount fs3k70 -N ess3k5a
3. Shut down GPFS only in canister A. (Customer task)
# mmshutdown -N canister A
Example:
[root@ess3k5a]# mmshutdown -N ess3k5a
4. Remove canister A from the enclosure. (SSR task)

the network cabling needs to be done as recorded here.
Disconnect high speed and management network cables from canister A ONLY and remove the
canister from the bottom slot of the enclosure.
Note: Do not unplug power cables to either PSU.
5. Install the hardware – add an adapter to the available middle slot in canister A. (SSR task)
Remove top cover of canister A and install one adapter in the 3
rd
PCIe slot that is located between
the two existing adapters. For more information about these steps, see the IBM Elastic Storage
System 3000: Service Guide.
