4. Remove canister A from the enclosure. (SSR task)
Record the high speed and management network cabling to canister A. 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 ONLY and remove the
canister from the bottom slot of the enclosure.
Note: Do not unplug power cables to either PSU.
5. Install the hardware – add an adapter to the available middle slot in canister A. (SSR task)
Remove top cover of canister A and install one adapter in the 3
rd
PCIe slot that is located between
the two existing adapters. For more information about these steps, see the IBM Elastic Storage
System 3000: Service Guide.
6. Insert canister A into the enclosure again and do basic checks. (SSR task)
a. Put back the top cover of canister A and insert it back to its original canister slot (bottom).
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 by using the “essserv1” service ID.
e. Perform the following checks in the essutils menu:
i) Option 2. Quick storage configuration check
ii) Option 3. Check enclosure cabling and paths to disks
Both options must be successful. Option 2 must show six network adapters.
Example:
localhost: Valid Network Adapter Configuration. Number of Adapter(s) found: 6
These checks are run per canister.
7. Incorporate new interfaces to the existing single master bond in canister A. (Customer task)
To configure each of the two new ports to be either InfiniBand or Ethernet, see the ConnectX-5 VPI
support on ESS 3000 topic in the IBM Elastic Storage System 3000: Quick Deployment Guide. Contact
technical support, if required.
8. Start GPFS in canister A. (Customer task)
# mmstartup -N canister A
a. Verify that GPFS is active on both A and B canisters.
# mmgetstate -N ESS 3000 nodeclass
b. Do the following extra steps on canister A, 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
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:
