Hi, I had my systems mirrored and bootable of the mirror. However, since Y@K testing, I have not been able to restore the mirror. What happened???
We recovered the systems with Ignite, which did not carry over the mirror. When I try to recreate the mirror, all goes well until I mirror the Lvols, at which time a get a message that states: "LIF information corrupt or not present. c3t5d0. Use the MKBOOT comand to initialize the LIF area. I have recreated several times and cannot get past this point. I have been using an HP "Cookbook" to perfrom this procedure. I have a question. should I "dd" the /dev/vg00 after I remove all mirrors to remove any prior "trace" of usage???
Thanks,
Tommy

Re: Rebuilding VG00 Mirror
Then
#vgextend /dev/vg00 /dev/dsk/cXd0s2
#lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/cXd0s2
etc...
and finally
#lvlnboot -r /dev/vg00/lvol1
#lvlnboot -s /dev/vg00/lvol2
#vgcfgbackup vg00
Good luck

Re: Rebuilding VG00 Mirror
Did you do a pvcreate:
#pvcreate -B /dev/rdsk/cXd0s2
Before?
This is how you should have started...

SolutionI also had to change the tome for Y2K purpose on some systems (though they had time machine installed, they didnt trust the results...)
but I then split the mirror and let them work with one copy and synced after using the disk that stayed 1999 dated.
I suppose the best is to start from scratch or to use your make_recovery but before invert your disks => install on you 2nd disk using make_recovery
Tell me how things go
Best of all
Victor

Re: Rebuilding VG00 Mirror
I must have really had some I/O errors in my fingers and eyes last time..I even had typed my intro message for the dd command /dev/vg00 , when I meant the /dev/rdsk/c3t6d0.. good thing I didn't try that..
Thanks
