I may repeat myself but if you followed my previous post, where I mentioned how to do the dd, you should have understood why HP did not caution the way you wanted to do the dd.
I have a proper clone of a disk that knows only one disk in vg00, thus no errors
You have a copy of a single disk from a vg00 which is mirrored... (so all will be stale...)
...

Now you havent said since your posts are unclear to me (which boxes are doing what..)
On what box are you working with now. How was it mounted, did you test if you could reboot from the second disk?
On what disk have you booted now?
Is this disk the Primary?
etc...

Subsidiary question: You have nowhere a golden image? even for your production machine?
Are you completely relying on a mirrored rootvg?

Sorry for confusion..!!

This is a test environment on which am testing the clone behavior .. initially on this server 2 hdd with 1 vg00.. which was in mirrored state . have tested server was able to boot on either of single disk ..

Then.. have inserted a new disk and build a new mirrored disk ..bootable ... then without any proper reduce .. have removed that disk and rebooted the server and now am trying to remove the error that am getting with vgdisplay ..

I believe have done some wrong step to reduce the VG and LV mirror path for new disk (that had removed ) and now mirroring is totally broken ... only primary disk is active now now ..

From here I want to ... remove all error from VG and rebuilt the mirroring i.e. as rollback the server it it's initial state ..

Guide me how I can remove all above error (1st Thread) from this server

Hi Shiri,

Request you to provide answers and o/p of some commands:-


1. Is this lvreduce done with any specific reason? the question is have you seen that disk has gone bad physically . or were there any amber on the disk?
2. the o/p of sautil /dev/ciss0 is needed. which can show that Disk is, if you cannot see the disks physically.
ioscan -m dsf
3.strings /etc/lvmtab
4. need to c the full o/p of vgdisplay -v.
