I have a set of HP 4500 G2s 14.4 model and I will be installing them for the first time. They appear to have come with SAN/iQ version 9.0 and I would like them fully updated before I actually configure them and throw them into production. This will be my first time working with the P4000 SAN Solution. SAN/iQ seems to only be a console management utility. Is this correct? If so is there anything to upgrade on the nodes themselves?
You need to install the CMC, in which you'll find an Software update menu. Before installing any of your storage nodes, download all available updates through the CMC (it's > 5Gb, so be patient).
Once the CMC is running the latest version (current is 9.5.00 build 1222) you can start adding your storage nodes. The CMC will notice they're not running the latest version, and will offer an update for all nodes.
Only once all nodes are fully up to date you should start creating your management group and clusters.
SanIQ is not just the CMC, it's the OS running on the storage nodes.
Also make sure you're installing the latest application aware snapshot manager and DSM for MPIO software on your windows servers.
