It will require a card, which I have now got, and the current configuration is stored on all the disks.<BR /><BR />I know how to do it, but is it prudent to back up the data on the disks before I do it?<BR /><BR />Many thanks.<BR /> Thu, 31 Jul 2008 10:12:37 GMT https://community.hpe.com/t5/operating-system-openvms/upgrading-a-hsz-controller-firmware/m-p/4243658#M90642 Nigel_18 2008-07-31T10:12:37Z https://community.hpe.com/t5/operating-system-openvms/upgrading-a-hsz-controller-firmware/m-p/4243659#M90643 Yes, please do a full backup. I don't remember that a HSZ upgrade ever failed, but I've seen a few cases where doing modifications to a system caused data loss and we were _very_ happy that we had a backup.
