Problems with VG00
I have a big problem. I have a server with HPUX 11.00 and the VG00 was setting to work with Mirror, but always that the sync process ran the mirror disk was unavailable status. I try to reconfigure the mirror settings but when I try to extend the VG00 again and run vgscan -v command the vg00 didn't appear in the lvmtab file. I believe my problems with mirror happend because of the vg00 trouble.
I read a article about LVM Maintenance Mode on HPUX and I saw it's possible to export/import the VG00 in this Mode. My question is: My problem will be solved if I export/import the VG00 in this Mode???
Please anyone help me!!!!
Regards

Re: Problems with VG00
PS.: the disk c1t6d0 was the mirror disk, but now I remove the mirror configuration, so the VG00 is using only the disk c2t6d0.

Re: Problems with VG00
A. pvcreate ├в B /dev/rdsk/c?t?d?
(to make the local disk2 to a bootable physical volume.)
B. vgextend /dev/vg00 /dev/dsk/c?t?d?
(to encase local disk2 into volume group vg00)
C. mkboot ├в l /dev/rdsk/c?t?d?
(to place the boot utilities into the boot area of the disk)
D. mkboot ├в a ├в hpux ├в lq (;0)/stand/vmunix├в /dev/rdsk/c?t?d?
( points disk to /stand Dir.)
NOTE: -lq needed if only 2 disks exist in the mirroring; otherwise when booting it won├в t boot (if one disk is bad) and need to do ISL> hpux-lq
E. lvextend ├в m 1 /dev/vg00/lvol1 /dev/dsk/c?t?d?
(do this for all lvols on disk1 to disk2)
F. lvlnboot ├в b /dev/vg00/lvol1
(make bootable lvol)
G. lvlnboot ├в r /dev/vg00/lvol3
(makes root lvol)
H. lvlnboot ├в s /dev/vg00/lvol2
(makes swap lvol)
I. lvlnboot ├в d /dev/vg00/lvol2
(makes lvol2 dump space)
J. lvlnboot ├в v
(to confirm you see both bootable disks)
K. lvdisplay ├в v /dev/vg00/lvol[1-?]
(to ensure both disks are available and current/synched and not stale)
L. setboot ├в a ?/?/?/?.?.?.?.? (physical address)
(sets disk2 as backup boot disk in case primary failes)
NOTE: the ├в a is for alternate, if primary is needed the argument is -p

Re: Problems with VG00
Let me explain better...
There was a mirror configuration on this server, but the mirror disk (c1t6d0) crashed and I tried to change the disk twice, but all the time, the disk c1t6d0 was unavailable when the sync process started. Because of that I remove the mirror configuration and changed the disk (c1t6d0) again and tried to reconfigure the mirror, but when I tried to run the command vgscan -v to recreate the lvmtab file, the VG00 didn't appeared.
Now Can you understand???
Sorry for the distarbe...
