While you could do a root mirror break-off, I'd rather use Live Upgrade with Solaris. That way you build up the new boot environment and then boot onto it. If you want to patch, you use LU and the same OS level on both sides. Then you patch the inactive boot environment from the active BE, then activate the other BE and reboot onto it.

Hello, I've read a few places on the internet that a fairly easy and straight forward way to safetly break your rootdisk mirroring for purposes of patching the Solaris OS, is to turn off your machine and remove your root-mirror drive from the machine. Boot off of your rootdisk, do your patching and if everything goes ok, put your rootmirror drive back in the machine, vxattach it back into the mirror. If the patching fails for some reason power down the machine, remove the rootdisk drive put in the rootmirror drive and boot then put the rootdisk drive and have it resync off of the rootmirror disk. Is this a supported way of rolling back from patching? Is there any documentation that thoroughly describes the process? It certainly seems much easier than the documenation I've read from Symantec that explains how to remove the rootmirror entirely from a software level. Thank you for any pointers in this matter.
