Data data loss inevitable?

Yep. To actually be able to use the disks for RAID in SE3310, the admin would need to "deinitialize" the disks first.

Best bet is, backup your data before you do this movement, and
That sounds kinda awkward - suppose the array breaks (but the disks don't). In that case, the data is lost? Doesn't sound too professional to me... I mean, yes, of course you do backups, sure. But at least I only do one backup per day. If the array breaks shortly before the backup starts, then one day of work is lost.

Hard to imagine that Sun really wants its users to go that route.

also backup the current storage configuration file .xml
What XML file? The RAID is configured and setup from "inside" the SE3310 over the telnet interface.

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. SEE ALSO
