How to Mirror LV and umirror after to change PVs...
Greetings
Im running HP UX B 11.11 and Im not sure on how to do this request to "mirror current 5 LVs on vgSPAN to the new LUNs assigned to the VG and unmirror the LVs and finally return the 12 LUNs to SAN storage" The existing LVs were extended to accommodate a user request to extend 2 FS on this VG
This is my vgdisplay -v | more output:

What puzzles me is at first look is that you are using at least 6 PVs (even 12...) in each LV I suppose for performance ( using PVG ...).
Even if system doesnt say so you are in almost stripped mode (distributed)...
I dont see how, with 5 new PVs you can achieve the same (it will be unbalanced...)

Reason: typo...
I totally forgot i posted this entry! The entry is not entirely correct. I was doing fine until i reached the part where i had to unmirror the old disks to return to SAN team
I was really nervous when i was doing lvreduce, and i missed the space in this syntax:
So i had to do a bit of reverse engineering here. I had to lvextend -m again then lvreduce it and finally vgreduce from VGSPAN to clear the old disks from usage.
need to confirm:
we have a system with two VIOs each serving a partition on a local disk to a client LPAR. That client LPAR has them both in a VG which is mirrored (exact). So each disk has a copy of the client LV that the client VG supports. This is the setup that was bequeathed to us by the... (3 Replies)
OK, I upgraded to the latest version of Solaris 10. Perhaps 'upgrade' isn't the right term because I reinstalled the root/boot drive with Solaris 10. Prior to this I had 4 physical drives. The first two had "/" and "/usr", the other two had a /var/audit and /home. I initially booted from cdrom and... (7 Replies)

I've looked a little but haven't found a solid answer, assuming there is one.
What's better, hardware mirroring or ZFS mirroring? Common practice for us was to use the raid controllers on the Sun x86 servers. Now we've been using ZFS mirroring since U6. Any performance difference? Any other... (3 Replies)
