We achieve high availability using a SAN for MQ. I need to update our CSD level. How do I go about it? Do I need to install it, fail it over, then install it on the other node or just install it one time?
Thanks. |

It depends on if the 'executable' programs are installed on the SAN. If they are not then you need to do both sides.

| Yeah, we have two seperate installs and only the qmgr directory structure is on the san. I'll have to install it on both sides. |

Yes
Install it on the one that is not currently running. Failover and leave the system with the new CSD for a while, maybe a week and install on the other one if you don't have any problems. |
