How to separate boot disk mirror (for emergency reboot)?
We normally run under Solaris 10 with 2 boot disks that are encapsulated and mirrored using VxVM v5.0MP1
Prior to patching, we want to protect ourselves by somehow splitting the mirror...such that the second disk is separately bootable..into it's own VxVM, as if you had encapsualted the second disk alone, without mirroring.
I'm not even sure if this is possible.
We typically boot from the primary disk (1st disk), and install patches.
If the patches cause a problem and the system fails to boot,
we want to boot from the 2nd (separated disk), and later....mirror 2nd disk back to the 1st disk,
This seems like such a mystic science....I have not seen any articles about it or documentation from Symantec.
Any assistance is most appreciated.
