9. Mount file systems to canister A again. (Customer task)
a. Check mounted file systems and mount to canister A again, if necessary.
# mmlsmount fs1 -L
or
# mmlsmount all -L
b. Move the quorum node back to the original state, if necessary.
10. Prepare canister B (top canister slot) for an adapter MES. (Customer task)
a. Determine the node class of the ESS 3000 enclosure where you want to perform MES upgrade.
# mmvdisk nodeclass list
b. Display the state of the nodeclass associated with the ESS 3000.
# mmgetstate -N the ESS 3000 nodeclass
Example:
[root@ess3k5a ~]# mmvdisk nodeclass list
node class recovery groups

c. If canister B 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 the node which is not in this enclosure’s nodeclass
iv) If necessary, to remove a quorum node from canister B, issue the following command:
# mmchnode –quorum -N canister B
11. Unmount file systems that are mounted on canister B. (Customer task)
Unmount GPFS file systems from canister B:
# mmumount fs1 -N canister B
or you can unmount all file systems at a time from canister B.
# mmumount all -N canister B
