5. For MES adapter installation, do the following steps (SSR task).
a. Open each canister.
b. Insert the new high-speed card into a free PCIe port.
For more information about these steps, see the IBM Elastic Storage System 3000: Service 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 options on each
canister:
• Option #3. Quick storage configuration check
• Option #4. Check enclosure cabling and paths to disks
Both options must be successful. Option #3 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 the new interfaces to the existing network master bond (customer task).
a. Log in to each canister and issue the following commands:
1) To get the information about the interfaces, issue the following command:
ip a
Ensure that the two additional interfaces are listed in the output. The information that is
captured in this step can be used for comparison. Copy and paste the names of the master
bond and the two additional interfaces into a note. They are needed in the following
commands.
b. For an MES upgrade for EC64 (InfiniBand), issue the following commands:
# nmcli c add type infiniband ifname <new interface name #1> master <bond name>
# nmcli c add type infiniband ifname <new interface name #2> master <bond name>
c. For an MES upgrade for EC67 (Ethernet), issue the following commands:
# nmcli c add type ethernet ifname <new interface name #1> master <bond name>
# nmcli c add type ethernet ifname <new interface name #2> master <bond name>
d. To see a list of the existing interfaces in the bond, issue the following command:
# nmcli c
Example
[root@ess3k5b ~]# nmcli c add type infiniband ifname ib4 master bond0
Connection 'bond-slave-ib4' (30d93d60-0846-46c6-8baf-53e1093e67eb) successfully added.
[root@ess3k5b ~]# nmcli c add type infiniband ifname ib5 master bond0
Connection 'bond-slave-ib5' (a1c3bdfc-1b49-49a5-8966-19d6e91c4c56) successfully added.
