Please post the outputs of all the commands listed by MadeInGermany in post#4. The disk might be in use as swap space.

Also, if your filesystems are ufs, please see this thread

Backup root disks

and in particular my "EXTRA NOTE" on my post. It's important that you dump the snapshotted device.

Why do you still contemplate breaking any mirror in order to do patching? You may be thinking that you can keep an original unpatched copy in case something goes wrong but, generally, it is always more difficult to boot the second copy than you think in these circumstances.

Patching doesn't usually go wrong but, if it does, reinitialising a filesystem and restoring from backup (ufsdump in this case) is usually the easiest and quickest route in my experience.

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
