ii) Ensure that correct entries are listed in
verbsPorts
for the target node class by issuing the
following command:
/opt/ibm/ess/tools/samples/essServerConfig.sh node class name
# mmlsconfig -Y | grep -i verbsPort
Example:
[root@ess3k5a ~]# mmlsconfig -Y | grep -i verbsPort
mmlsconfig::0:1:::verbsPorts:mlx5_1/1::
mmlsconfig::0:1:::verbsPorts:mlx5_0/1 mlx5_1/1:bodhi1-ib,gssio2-ib,bodhi_nc1,ems:
mmlsconfig::0:1:::verbsPorts:mlx5_0/1 mlx5_1/1 mlx5_2/1 mlx5_3/1:ess_x86_64:
mmlsconfig::0:1:::verbsPorts:mlx5_2/1 mlx5_3/1 mlx5_4/1 mlx5_5/1:ess_x86_64_mmvdisk_5:
mmlsconfig::0:1:::verbsPorts:mlx5_2/1 mlx5_3/1:ess_x86_64_mmvdisk_6:
mmlsconfig::0:1:::verbsPorts:mlx5_0/1:gss_ppc64:
18. Mount file systems on canister B again. (Customer task)
a. Check mounted file systems and mount to canister B again, if necessary.
# mmlsmount fs1 -L
or
# mmlsmount all -L
b. Move the quorum node back to the original state, if necessary.
ESS 3000 memory MES upgrade
Overview
This procedure is intended for the non-concurrent (offline) memory MES installation of feature code ACGB
to upgrade cache memory with additional 768 GB (24 x 32 GB) for each system.
Objectives
• Install all memory DIMMs to both server canisters.
• Configure GPFS pagepool size to 60% (of cache memory size).
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 memory.
6. Power on ESS 3000 and do basic checks.
7. Configure GPFS page pool size to the 60% target.
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.
