doc for 4 disk vg00
Whose got a good doc listing out the procedure for mirroring vg00 when vg00 has 4 disks?
I'm trying to find out if strict allocation is used everywhere.

/stand and / need to be on the boot disk. Beyond that you can use lvchange to change strict allocation if need be to re-arrange the deck prior to the mirror.

Re: doc for 4 disk vg00
What does "..arrange the deck prior to the mirror.." mean?
Besides the strict allocation policy on the two disks, pvchange -B only needs to used on the first disk that includes /, stand and swap. Right? While the second disk woudln't use -B.
And the same goes for the bootlif only appearing on the first disk, used in the setboot commands, lvlnboot, etc.
In summary, as long as none of the o/s lvols, especially / and stand and swap are not on the 2nd disk, then this is a straight mirroring.
You know I can't find the PA-Risc cookbooks on the itrc anymore. Does anyone have a copy?

For PARISC at the end of this document, which I recommend you read before mirroring as it describes what needs to be done to recover given your starting point.
