1 These stages create, verify, or remove the tagged files required for a rolling upgrade. The time that it takes to run
one of these stages depends on the speed of the member executing the command, the speed of the storage, and
whether the member executing the command is the CFS server for the root (/), /usr, and /var file systems. Consider
relocating these file systems to the member where you will run the clu_upgrade command.
2 After rolling the lead member, use parallel rolls to roll multiple members simultaneously and shorten the time it
takes to roll a cluster.
You can use the following procedure to upgrade a TruCluster software Version 5.1A cluster to
Version 5.1B, and to upgrade a cluster that is already at Version 5.1B.
1. Prepare the cluster for the rolling upgrade (“Preparation Stage”):
a. Choose one cluster member to be the lead member (the first member to roll). (The
examples in this procedure use a member whose memberid is 2 as the lead member.
The example member's host name is provolone.)
b. Back up the cluster.
c. If you will perform an update installation during the install stage, remove any blocking
layered products, listed in Table 4-6 “Blocking Layered Products”, that are installed on
the cluster.
