is received.
Note: It is not recommended to use mismatched PSUs in a 5147-102 enclosure.
Miscellaneous equipment specication (MES) instructions
An IBM Elastic Storage System 5147-102 Storage Enclosure hardware change can be done by using the
MES instructions.
Upgrading an IBM Elastic Storage System 5147-102 Storage Enclosure from
a half-populated to a fully populated conguration
This non-concurrent MES procedure involves shifting down customer workload, adding 50 more HDDs
to an existing IBM Elastic Storage System 5147-102 Storage Enclosure to ll up all 102 drive slots with
HDDs, and returning the system to the customer for conguration of the new storage.
This procedure is only applicable to an IBM Elastic Storage System solution with a single half-populated
IBM Elastic Storage System 5147-102 Storage Enclosure.
MES upgrade steps
Refer to the following steps to upgrade an 5147-102 from a half-populated to a fully populated
conguration:
1. Customer task: Stop using the ESS 5147-102 enclosure.
2. Customer task: Unmount affected le systems that are mounted on the ESS 5147-102 enclosure and
shutdown GPFS.
mmshutdown -a
3. Identify the ESS 5147-102 storage enclosure to be upgraded.
a. Perform the following checks in the essutils menu and gather ESS 5147-102 serial number in
the SSR Checks for ESS 3500 nodes’ section:
i) Quick storage conguration check
ii) Check enclosure cabling and paths to disks
b. SSR Checks for ESS 3500 nodes > 1. Quick storage conguration check.
