Mirror after cold start from Make_Tape_Recovery

[Yodi_1]

Hi, My system is rx4640, running UX 11.23, Using Make_Tape_Recovery to upgrade disk from 36GB to 72GB, recovery running well, but I can't reconfigure the Mirror.
When I try to configure mirror, at the step to run vgextend, I got message "# Vgcfgbackup: Invalid LVMREC on physical Volume /dev/rdsk/c3t0d0"
When I checked at vgdisplay it show: Cur PV and Act PV is not match.
I followed the information I got from KMINE (2200100364), but when I try to recreate /etc/lvmtab, it can't create. So please help me if you know the solution

Hi,

lvextend is to be used to create mirroring not the vgextend. try running command vgscan -v before running lvextend

Hi Yodi,
I dont to what point an rx and rp box are different (We here dont have itanium boxes yet...)
So dont take for granted my thoughts...
If I understand well you did a make_recovery tape and used it in order to exchange your 36GB disks to 72GB, is that so?
Can you tell us a bit more?
Which 2 disks did you change/ which is the one you booted from now:
echo 'boot_string/S'|adb /stand/vmunix /dev/kmem
...
I would restart (since you just did almost a fresh install) once I know sure which disk Im on by going to /etc, mv lvmtab lvmtab.bak, mv ioconfig ioconfig.bak, then reboot or ioscan followed by insf -C insf -e... then vgscan -v and see if you have just the disk in lvmtab now. From then its a pvcreate (-f) the second disk and after I suppose you know...
The doc you used was about a vgreduce to remove a disk that failed, you case is not similar since if I understood well you reinstalled on new bigger disks and now want to mirror but cannot vgextend

Courage
All the best
Victor

Hi Yodi,
You need to recreate the LVMREC on the disk.
Check or run this commands.
1. Establish the mirroring. Make sure the auto string is "hpux -lq".
2. Find out the idle time when your system will not be busy. Replace the mirror disk with a new disk.
3. Run ioscan -f and make sure the new disk is claimed. At this time lvlnboot, vgdisplay etc., will give you errors.
4. Do a vgcfgrestore onto the new disk.
vgcfgrestore -n vg00 /dev/rdsk/c3t0d0
vgchange -a y vg00
mkboot -l /dev/rdsk/c3t0d0
mkboot -a "hpux" /dev/rdsk/c3t0d0
vgsync
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
lvlnboot -R
lvlnboot -v
Make sure both the disks are listed as bootable. Verify the mirrors.

Borislav

bad option here:

mkboot -a "hpux" /dev/rdsk/c3t0d0
must be use :
mkboot -a "hpux -lq " /dev/rdsk/c3t0d0

and check with
lifcp
#lifcp /dev/rdsk/c3t0d0:AUTO -

vgsync
"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
lvlnboot -R
lvlnboot -v"

Here you need only
lvlnboot -R
lvlnboot -v

And finaly you must edit
/stand/bootconf
and add second disk

But any way you have problem adding second disk into VG

Did you create partitions using
idisk ?

Team,
Thanks for your help and support, By the way I got the Solution, when I followed again document from KMINE (2200100364).
#strings /etc/lvmtab == mirror disk still in lvmtab
#mv /etc/lvmtab /etc/lvmtab.orig
#vgscan -v
#vgreduce -f /dev/vg00
#vgscan -v
#strings /etc/lvmtab ==== in here the mirror disk alreday dissapear

and then after that I followed document KBRC00014526 to create mirror in IA for HP-UX 11.23

Again thanks for your support.

Regards
Yodi
