Problem removing a LV located in disks that were removed from an EVA

[compiler]

Hi,

By mistake, an EVA-exported disk was removed before lvremoving & vgreducing it in the O.S. (HP-UX 11v23).

When we tried to remove the logical volume that contained that physical disk, we got the following error:

# lvremove /dev/vg06/lvol1
Current path "/dev/dsk/c3t0d2" is an alternate link, skip.
Current path "/dev/dsk/c4t0d2" is an alternate link, skip.
Current path "/dev/dsk/c5t0d2" is an alternate link, skip.
Current path "/dev/dsk/c6t0d2" is an alternate link, skip.
Current path "/dev/dsk/c7t0d2" is an alternate link, skip.
Current path "/dev/dsk/c8t0d2" is an alternate link, skip.

Current path "/dev/dsk/c6t1d2" is an alternate link, skip.
Current path "/dev/dsk/c8t1d2" is an alternate link, skip.
The logical volume "/dev/vg06/lvol1" is not empty;
do you really want to delete the logical volume (y/n) : y
Logical volume "/dev/vg06/lvol1" has been successfully removed.
vgcfgbackup: Unable to read the physical volume.: Device busy
vgcfgbackup: Invalid LVMREC on Physical Volume /dev/rdsk/c2t0d2

If I do an "vgdisplay", I can see that the LV has been removed, but I can still see the old "Physical Volumes" (the PVs of the EVA disk that was removed from the EVA).

Is it safe to do an "vgreduce" command for the missing disk and its alternate paths and the "rmsf -a" of the device files?

How do I fix the "vgcfgbackup" error?

Hi,

Yes. You can safely remove the missing PV's using -f option.

#vgreduce -f /dev/vg01

[compiler]

I didn't work. I did "vgreduce -f vg06" and the PV still appear in vgdisplay, although they are marked as "Unavailable".

"vgreducing" all the /dev/dsk/xxxxx files worked for the "alternate paths" and the primary path.

Thanks a lot for your help.

Hi,

Try this,

# vgreduce -l

# vgreduce -l /dev/vg01 /dev/dsk/c1t2d0

[compiler]

"vgreducing" all the physical paths from the VG solved the problem.
