SSD Update HA cluster Procedure

Nanoman

Hello everyone,

I need to upgrade the SSDs in a customer's HA cluster, and it is not clear to me how to proceed.


From the guide:

"High availability

In an HA cluster, you must upgrade the SSD firmware on each appliance individually as follows: 

  1. Verify if both appliances in the cluster require the SSD upgrade (see information above). Appliances in an HA cluster will not always have the same SSD model.
  2. If both require the upgrade, upgrade one appliance first.
    After it restarts, upgrade the second appliance."



The question is, how do I upgrade the two nodes separately?


If I access node 2 via ssh (CLI (5->3, ssh -F /static/ha/hauser.conf hauser@IP) the commands
system ssd show/update are not available.

Via CLI -> 4, I can only work on node 1.

I was thinking of doing it this way:
1) switch from GUI node 1 (PRI) to AUX.
2) Via CLI -> 4 update Node 2 (at that time be Primary)
3) once Node 2 is back up and HA green, switch Node 1 back to Primary and perform the same operation via CLI -> 4.

Is this correct? Thank you in advance

    You can jump from advanced shell to console by using the command: 

    # cish 

    So do the SSH part to the aux advanced shell and enter cish. 
    You will not see on which appliance you are after entering cish as it switched to the console prompt.
