17. Start GPFS on the two canisters (or the whole cluster if needed for quorum).
18. Issue the following command on the affected recovery group. This command adds the new capacity,
and rebalancing data begins onto the new disks.
# mmvdisk recoverygroup resize --recovery-group ess3k recoverygroup
19. Update the node class server configuration for 24 drives by issuing the following command:
# mmvdisk server configure --update --recycle 1 --node-class this ESS 3000 node class
20. If the GPFS autostart was enabled and had to be disabled, enable autostart again. Also, if the
automount was disabled, you can enable the automount again. You can resume normal cluster
operations after the GPFS autostart and the automount.
The customer can use the new space by creating new vdisksets from the available space. When the
vdisksets are added to the existing file system (if required), the restripe operation can be run. For more
information, see IBM Spectrum Scale: Administration Guide.
ESS 3000 adapter MES upgrade: EC64 and EC67
Overview
This procedure is intended for the concurrent (online) adapter MES installation to add the third adapter to
each of the server canisters of ESS 3000. The adapter options to choose from include EC64 (InfiniBand)
and EC67 (Ethernet).
Because the adapter MES is designed to be a concurrent procedure, it is recommended to perform this
procedure during a service window of low activity.
Objectives
• Install the new adapter pair, one in each server canister, by using an online process.
• Incorporate the new interfaces into an existing single master bond.
High-level MES upgrade steps
1. Prepare canister A (bottom canister slot) for adapter MES.
2. Unmount file systems that are mounted on canister A.
3. Shut down GPFS only in canister A.
4. Remove canister A from the enclosure.
5. Install the hardware – add an adapter to the available middle slot in canister A.
6. Insert canister A into the enclosure again and do basic checks.
7. Incorporate new interfaces to the existing single master bond in canister A.
8. Start GPFS in canister A.
9. Mount file systems on canister A again.
10. Prepare canister B (top canister slot) for an adapter MES.
11. Unmount file systems that are mounted on canister B.
12. Shut down GPFS only in canister B.
13. Remove canister B from the enclosure.
14. Install the hardware – add an adapter to the available middle slot in canister B.
15. Reinsert canister B into the enclosure and do basic checks.
16. Incorporate new interfaces to the existing single master bond in canister B.
17. Start GPFS in canister B.
