Why aren't you using ZFS for mirroring?

only thing i can think of is stop the guest domains, tear down d50, d60, boot off cdrom single user, fsck the rdsk's of d50 and d60, run this several times to see if it repairs, mount root fs, remove md's d50 and d60 from vfstab and then reboot. see if you can get a stable os. make sure the guest ldoms don't come up because they will obviously be looking for the metadevices.

i'm not sure about ldom's because i haven't had the pleasure of working with them as of yet but i'm just thinking of this as if a stand alone sol10 install wasn't working after a reboot with metadevices.
js-client_t5220 is the control domain; and I confirm that I am rebooting the control domain and the control domain is failing to come online with the errors reported earlier. I did not spend much time trying to fix it using fsck since this is a new server so I did re-jumpstart the server (control domain and guest domains) and things are up and running well now. I did not reboot yet but I will make sure all guest domains are in "inactive" state before I reboot the control domain.

And to answer your question, I have a guest domain for each directory that is assigned to a slice and each is named after an application I will be installing in that domain and each slice is mounted to dx for RAID1 mirroring; e.g. slice /export/home/sgw is mount to d50. d5 is a mirror and has two members as you can see below:

y don't need mount in the control domain to mirroring !!!

and then stop the guest domains and reboot the control domain

starsol - zfs is a filesystem and svm is a volume manager. they are different things. however, zfs has its own integrated volume management. zfs is free to use with sol10 as well as other flavors of unix.

The control domain is on /dev/md/dsk/d10 and the rest are for logical domains. I did re-jumpstart the control domain and created the guest domains (but did not load OS on the guest domains yet). As you can see below, no problems when rebooting the control domain:
