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
Overview
This procedure is intended for the non-concurrent (offline) 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).
Objectives
• Install the new adapter pair, one in each server node canister, by using an offline process.
• Incorporate the new interfaces into an existing single master bond.
High-level MES upgrade steps
1. Stop all I/O to one or more file systems that are mounted on the MES target ESS 3000 system.
2. Unmount one or more file systems and prepare GPFS to stay in the offline mode.
3. Shut down GPFS.
4. Power off ESS 3000.
5. Install the hardware - add the new pair of adapters to the available middle slot in both canisters.
6. Power on ESS 3000 and do basic checks.
7. Incorporate new interfaces to the existing single master bond.
8. Restore GPFS normal operational mode.
9. Mount one or more file systems that are designated to the target ESS 3000.
10. Resume I/O.
• Customer tasks are steps 1 - 3.
• SSR tasks are steps 4 - 6.
• Customer tasks are steps 7 - 10.
Summary
The goal of this procedure is primarily to add a third high-speed adapter into each ESS 3000 canister.
Customer can add supported InfiniBand or Ethernet adapters into the third PCI slot.
• The PCI address is af:00.1
• The adapter type is ConnectX-5 [ConnectX-5 Ex]
