I am required to upgrade our HP P4300 G2 SAN's firmwave and OS. Currently we have 3 san nodes, 2 nodes have the os 8.5 version and the other 9.0.
My plan so far is to:
Commence with an interactive firmware DVD update on SAN 3, then SAN 2 and then SAN 1. After updating the firmware on each of the nodes, a test will be carried to ensure the volume is functional.
After the firmware update then we will commence with the OS upgrade, this is accomplished by connecting the CMC to the internet and then run an upgrade check and then upgrade the OS to the latest which is 10.5. This will be actioned after a full backup of the network. Again after upgrading the OS a test will be carried out on each on the volumes on every node.
Please let me know if there is anything missing here, I really do not want to skrew anything up as we have a LOT of business critical data on our SAN storage.
Thank you in advance,
