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.


Windows?, no thanks
