7) Double check and confirm that the GPFS automount is disabled by issuing the following
command:
# mmlsfs <filesystem name>
8) Ensure that autoload=no is under the nodeclass entry that is associated with the target ESS
3000 by issuing the following command:
# mmlsconfig
3. Shut down GPFS in both canisters by issuing the following command (customer task):
# mmshutdown -N <Node server names separated by a comma>
a. Ensure that the node servers associated with the target ESS 3000 are shut down by issuing the
following command:
# mmgetstate -a
4. Pull power cables that are connected to the ESS 3000 system (SSR task).
a. Confirm with customer to ensure that customer did all required steps, and then disconnect the
power cables.
b. To shut down the storage enclosure, unplug both power cords that are on both the sides of the
ESS 3000 system.
5. For MES memory installation, do the following steps (SSR task).
a. Pull out the ESS 3000 from the frame.
b. Open each canister.
c. Insert the additional DIMMS into each canister.
For more information about these steps, see the IBM Elastic Storage System 3000: Service Guide
or the Planning for hardware chapter of the IBM Elastic Storage System 3000: Hardware Planning
and Installation Guide.
6. Power on ESS 3000 and do basic checks (SSR task).
a. After basic checks completion, place everything back into the frame and reinsert power cables.
This step restarts the nodes.
You can use the procedure in the Installing chapter of the IBM Elastic Storage System 3000:
Hardware Planning and Installation Guide to do the following steps:
1) Plug your laptop to point-to-point to each container technician port.
2) Log in as essserv1.
3) Run the essutils command.
b. In the essutils command, use the SSR tools option to run the following option on each canister:
• Option #6. Check the memory
Running: /opt/ibm/ess/tools/bin/ess3kplt -t memory –local
