e. Turn on the GPFS automount by issuing the following command:
# mmchfs <filesystem> -A yes
f. Turn on the GPFS autoload by issuing the following command:
# mmchconfig autoload=yes
g. Double check and confirm that the GPFS automount is enabled by issuing the following command:
# mmlsfs <filesystem name>
h. Ensure that autoload=yes is under the node class entry that is associated with the target ESS
3000 by issuing the following command:
# mmlsconfig
9. Mount the file system (customer task).
a. Mount each file system individually by issuing the following command:
# mmmount <filesystem> -a
b. If you want to mount all file systems in all nodes, you can issue the following command:
# mmmount all -N all
c. Ensure that the file systems are up.
d. Confirm that one or more target file systems are mounted by issuing the following command:
# mmlsmount <filesystem> -L
10. Do health check by issuing the following command, and resume I/O because the MES is complete
(customer task):
# mmhealth node show
ESS 3000 storage drives concurrent MES upgrade
An online IBM Elastic Storage System 3000 (ESS 3000) MES upgrade is supported for customers who
want to upgrade a 12-drive ESS 3000 to a 24-drive ESS 3000.
To upgrade the system, the NVMe drives with the same size as the existing 12 drives must be used. This
MES upgrade doubles the available storage capacity in the existing ESS 3000. For this concurrent
upgrade, it is recommended to perform this operation during a period of low workload stress. Existing
customer recovery group and file system data are preserved during the MES upgrade.
Supported upgrade path: 12 NVMe ESS 3000 -> 24 NVMe ESS 3000
Prerequisites
• All new or existing building blocks must be at the ESS 5.3.5.2, ESS 3000 6.0.0.2 or later level. If the
setup has any protocol nodes, these nodes must also be upgraded to ESS 5.3.5.2 levels (underlying
