Re: HP-UX 11.23 failed internal mirrored vg00 disk
GREAT!!!
Thanks a lot, it's worked perfectly well.
I've removed the non-mirrored lvol.
I've reduced the mirrored lvols with lvreduce -k.
I've reduced vg00 with -f.
/etc/lvmtab still showed the failed disk, so I've moved it and done vgscan.
Now /etc/lvmtab only shows one disk, and vgdisplay doesn't throw any errors.
And also, lvlnboot now shows the correct information, and doesn't show errors (except some not activated VGs):
#lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t0d0s2 (0/4/1/0.0.0.0.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c1t0d0s2
Root: lvol3 on: /dev/dsk/c1t0d0s2
Swap: lvol2 on: /dev/dsk/c1t0d0s2
Dump: lvol2 on: /dev/dsk/c1t0d0s2, 0
lvlnboot: Volume group not activated.
Cannot display volume group "/dev/DATAVG".
lvlnboot: Volume group not activated.
...
Now I will go on with the standard vg00 mirror procedure.
Thanks a lot.

Re: HP-UX 11.23 failed internal mirrored vg00 disk
I've finally mirrored the vg00 lvols, and recreated the non-mirrored lvol (and this time I've mirrored it). I will restore its contents from backup.
Just one last thing.
When mirroring /dev/vg00/lvol2 it failed.
#lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c1t2d0s2
The newly allocated mirrors are now being synchronized. This operation will
take some time. Please wait ....
lvextend: Couldn't re-synchronize stale partitions of the logical volume:
I/O error
lvextend: Couldn't resynchronize logical volume "/dev/vg00/lvol2".
#lvsync /dev/vg00/lvol2
lvsync: Couldn't re-synchronize stale partitions of the logical volume: Device offline/Powerfailed
lvsync: Couldn't resynchronize logical volume "/dev/vg00/lvol2".
This message appears in /var/adm/syslog/syslog.log:
EMS [2459]: ------ EMS Event Notification ------ Value: "CRITICAL (5)" for Resource: "/storage/events/disks/default/0_4_1_0.0.0.0.0"
(Threshold: >= " 3") Execute the following command to obtain event details: /opt/resmon/bin/resdata -R 161153026 -r /storage/events/disks/default/0_4_1_0.0.0.0.0 -n 16
Results from resdata are attached.
All the other lvols have syncd well.
I've restarted the server, but it still doesn't sync.
Does anyone know what may be causing this?
Thanks a lot.

Re: HP-UX 11.23 failed internal mirrored vg00 disk
From the error you posted, the "good" disk is giving and IO error:
Disk at hardware path 0/4/1/0.0.0.0.0 : I/O request failed
You can check with lvdisplay -v /dev/vg00/lvol2, for stale PE's on the good disk.
You can also check the "good" disk running a read dd to see if any errors are reported.
