Record the high speed and management network cabling to canister A/1. After adapter MES is done,
the network cabling needs to be done as recorded here.
Disconnect high speed and management network cables from canister A/1 ONLY and remove the
canister from the slot of the enclosure.
Note: Do not unplug power cables to either PSU.
5. SSR task: Install the hardware – add an adapter to the available slot in canister A/1.
Remove top cover of canister A/1 and install one or more adapter pairs to the remaining available
slots. Please follow the placement priority carefully in the Prerequisites section above based on the
types of adapter pairs to be installed in this MES.
6. SSR task: Insert canister A/1 into the enclosure again and do basic checks.
a. Put back the top cover of canister A/1 and insert it back to its original canister slot.
b. Reconnect original high speed and management network cables.
c. Connect the new high-speed cables to the new adapter if provided by the customer.
d. Perform basic checks via the technician port in canister A/1 by using the essserv1 service ID.
e. Perform the following checks in the essutils menu:
• Option 2. Quick storage configuration check
• Option 3. Check enclosure cabling and paths to disks
Both options must be successful. Option 2 must show six network adapters.
7. Customer task: Incorporate new interfaces to the existing single master bond in canister A/1.
To configure each of the two new ports to be either InfiniBand or Ethernet, see https://www.ibm.com/
docs/en/ess/6.1.3_lts?topic=guide-connectx-5-connectx-6-vpi-support. Contact technical support if
required.
8. Customer task: Start GPFS in canister A/1.
# mmstartup -N <node name>
a. Verify that GPFS is active on both A/1 and B/2 canisters.
# mmgetstate -N <node class name>
b. Do the following extra steps on canister A/1, if MES is for InfiniBand:
i) Update the verbsPorts list, first start GPFS manually.
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>
9. Customer task: Mount file systems to canister A/1 again.
a. Check mounted file systems and mount to canister A/1 again, if necessary.
# mmlsmount <file system name> -L
Or
# mmlsmount all
b. Move the quorum node back to the original state, if necessary.
10. Customer task: Prepare canister B/2 slot for an adapter MES.
a. Determine the node class of the ESS 3500 enclosure where you want to perform MES upgrade.
