Old 09-14-2010
Here the steps I follow

- breaking the mirrors
Code:
metadetach d10 d12
metadetach d30 d32
metadetach d40 d42

- fsck the detached mirrors
Code:
fsck /dev/md/rdsk/d12
fsck /dev/md/rdsk/d32
fsck /dev/md/rdsk/d42

- Mount detached to modify /etc/system and /etc/vfstab
Code:
mount /dev/md/dsk/d12 /mnt

- Remove following line from /mnt/etc/system
Code:
rootdev:/pseudo/md@0:0,10...

- change following lines in /mnt/etc/vfstab
Code:
 /dev/md/dsk/d10  /dev/md/rdsk/d10  /     ufs  1  no
  /dev/md/dsk/d30  /dev/md/rdsk/d30  /var  ufs  1  no
  /dev/md/dsk/d40  /dev/md/rdsk/d40  /opt  ufs  1  no

To
Code:
 /dev/dsk/c2t500000E01998D020d0s0 /dev/rdsk/c2t500000E01998D020d0s0 /    ufs 1 no
  /dev/dsk/c2t500000E01998D020d0s3 /dev/rdsk/c2t500000E01998D020d0s3 /var ufs 1 no
  /dev/dsk/c2t500000E01998D020d0s4 /dev/rdsk/c2t500000E01998D020d0s4 /opt ufs 1 no

- Umount the Filesystem
Code:
umount /mnt

- Shut down the server for patching
- Patch the server
- Reboot the server
- a few days later attach the mirrors again

When the something happen during patching just boot from the mirror.

lvscan

LVSCAN(8)						      System Manager's Manual							 LVSCAN(8)

NAME

       lvscan - scan (all disks) for Logical Volumes

SYNOPSIS

       lvscan [-a|--all] [-b|--blockdevice] [-d|--debug] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose]

DESCRIPTION

       lvscan  scans all known volume groups or all supported LVM block devices in the system for defined Logical Volumes.  The output consists of
       one line for each Logical Volume indicating whether or not it is active, a snapshot or origin, the size of the device  and  its	allocation
       policy.	Use lvs(8) or lvdisplay(8) to obtain more-comprehensive information about the Logical Volumes.

OPTIONS

       See lvm for common options.

       --all  Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as
	      mirrors, but which are not independently accessible (e.g. not mountable).  For example, after creating a mirror using 'lvcreate  -m1
	      --mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       -b, --blockdevice
	      This option is now ignored.  Instead, use lvs(8) or lvdisplay(8) to obtain the device number.
