FC 10 device firmware upgrade and logical volmues

[GB Tek]

I'm needing to update the firmware on the HP FC array we use. I need to unmount the volume groups before applying the update to the controllers. I'm going to put the firmware in the root directory. I'll stop the SAP services but I don't know how to safely unmount the volume groups so I can update the firmware. Any ideas?

Hi,

You should be able to 'umount' all the filesystems that live on the FC10, and then do a 'vgchange -a n /dev/vg_yourvg' on all the VGs that are on it.

Hi,
Here's a way to upgrade with on line disks (don't need to reboot the server). It works only with mirrored disks !
