Has anybody done a firmware upgrade in a cluster environment without putting the whole cluster offline?
The problem is to continue offering a 7x24 service, so I want to have one node providing service while I make the upgrade into the other.
I have a 2-node AS4100 cluster with Digital Unix 4.0D + TruCluster 1.5 + PK3 and firmware rev. 5.1 and I don't want to stop the services that the cluster is offering.
I understand that an OS software upgrade requires to stop the cluster, but I suppose that a firmware upgrade doesn't.
Has anybody have experience with this? What are your opinions?
Thanks in advance
Edgardo
