I have vg00 on one 9 gig disk, and a 9 gig mirror disk.
I discovered vg00/lvol1 (aka /stand) is not mirrored due to a mistake in typing a few months ago.
But I have the rest of it mirrored.
Lvol1 is only 17 extents in size. I know lvol1 needs to be contiguous.
But do I need to unmirror and remirror all the other logical volumes to put lvol1's mirror in front? Do I need lvol1's mirror in front?
Assuming I do, I'll have to unmirror and remirror 8 logical volumes this way right?

Should I run the lvlnboot commands again then?
lvlnboot -r /dev/vg00/lvol3 /dev/vg00
lvlnboot -b /dev/vg00/lvol1 /dev/vg00
lvlnboot -s /dev/vg00/lvol2 /dev/vg00
lvlnboot -d /dev/vg00/lvol2 /dev/vg00
...or maybe just lvlnboot -R?
any advice? I have 2 ignite tapes. I'm not doing this until Sunday.

Re: hpux11.0 two mirrored boot disks with mirror in wrong order
yeah.. that's kinda it. I see it mentioned on 1/2 a line in hp doc LVMKBRC00005103 in step 5. But it's barely mentioned. And there's no explanation to it.
It strikes me as odd. I thought logical volumes allowed you to not have to worry about stuff like this. Perhaps the hardware only looks at the first 50 extents in a disk for /stand?
A half-hearted mention of the order of logical volumes in a document does not give me a warm fuzzy.

Re: hpux11.0 two mirrored boot disks with mirror in wrong order
Found it. In "man lvlnboot", I see it requires lvol1 to be the FIRST logical volume on the boot disk.
I'll run these commands, and run the lvlnboot -r,-b,.... instead of lvlnboot -R.
Thanks for the help.
