Hi

Probably not the best idea to ask for upgrade process from the web, however you should be fine in doing what you suggest.

Take at least 2 backups of the data, as well as your standard backup and have all 3 sets of disks on site for the upgrade. I have seen many times, specifically with DB backups where the first backup used doesn't work.

I would also make sure the disks are unmounted from the system before you physically pull them out or that the system is powered off (I'm unsure if your system provides hotswap).

When you replace the disks make sure they are accessible and fine and you can see and use them on the system.

Once confirmed you should be good to recover the data from the tapes.

Thanks

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME

       mkqdisk - Cluster Quorum Disk Utility

WARNING

       Use of this command can cause the cluster to malfunction.

SYNOPSIS

       mkqdisk [-?|-h] | [-L] | [-f label] [-c device  -l label] [-d [-d ...]]

DESCRIPTION

       The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.

OPTIONS

       -c device -l label
	      Initialize  a new cluster quorum disk.  This will destroy all data on the given device.  If a cluster is currently using that device
	      as a quorum disk, the entire cluster will malfunction.  Do not run this on an active cluster  when  qdiskd  is  running.	 Only  one
	      device  on  the  SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
	      RAID array is used for quorum disk redundancy).  The label can be any textual string up to 127 characters - and is therefore  enough
	      space to hold a UUID created with uuidgen(1).

       -f label
	      Find the cluster quorum disk with the given label and display information about it.

       -L     Display information on all accessible cluster quorum disks.

       -d     Increase debugging level.  Specify multiple times for more information.  Currently, specifying more than twice has no effect.
