LV Status: available/stale

[Mike_21]

hmmmm.... I happened to check if any available room was left on an LV, and the following came up!

#vgdisplay -v /dev/vg00

vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c0t4d0":
The specified path does not correspond to physical volume attached to
this volume group
vgdisplay: Couldn't query the list of physical volumes.
--- Logical volumes ---
LV Name /dev/vg00/lvol1
LV Status available/stale
LV Size (Mbytes) 48
Current LE 12
Allocated PE 24
Used PV 1

This doesn't look good and could explain the poor performance we have been experiencing? What would cause such a thing?

Thank

It looks like the mirrors are having a problem.

It suggests the disc at that address is down. I wouod recommend you get a hardware call placed quickly, as you are no longer protected by your mirroring

Mike,

Looks like you have a disk that have stop answering.
You could try a diskinfo first to see if he is completely down.

diskinfo /dev/rdsk/c0t4d0

if this command is not describing you the disk or if the size is zero then your disk needs to be replace.

if this works you could try to read the complete disk to see if he is readable:

dd if=/dev/rdsk/c0t4d0 of=/dev/null bs=1024k

If you receive some error while running this command or if there is some I/O errors written in /vad/adm/syslog/syslog then the disk needs to be replace.

If these 2 commands works fine you could then try a
vgcfgrestore on the disk, followed by a vgchange -a y.

Hi Mike,

Looks like your mirror disk has failed. Arrange for a replacement of the mirror disk.

Hope this helps.

Check if everything is ok in VG, if so, then try

lvchange -a y <lvname>
