Error in vgextend for alternate link

[hboo]

Hello all...

I want to add a alternate link for a disk belongs to a VG.

Output of vgextend command is:
#vgextend /dev/vg0x /dev/dsk/c18t0d6
.
.
.
vgextend: The physical volume "/dev/dsk/c18t0d6" is already recorded in the "/etc/lvmtab" file.

/etc/lvmtab contain:

^EM-zM-x|FM-^JM-^YM-^B^A/dev/dsk/c18t0d6

This is with "more" command

Somebody can help me to add alternate link /dev/dsk/c18t0d6 in my vg?

Thanks.

strings /etc/lvmtab

Then look to see which vg it is in...

The file
/etc/lvmtab
is binary, so a "more" will probably chrash your shell.
Do
# strings /etc/lvmtab

and you will see to which VG the device belongs.

obviously it is alreay included.

Another way to see which vg already has it:

vgdisplay -v |egrep "VG Name|c18t0d6"

OK, strings /etc/lvmtab results:
/dev/vg00
/dev/dsk/c2t0d0
/dev/dsk/c2t1d0
/dev/vgoracle01
/dev/dsk/c9t0d0
/dev/dsk/c12t0d1
/dev/dsk/c15t0d1
/dev/dsk/c27t0d2
/dev/dsk/c27t0d1
/dev/dsk/c24t0d0
/dev/dsk/c21t0d1
/dev/dsk/c21t0d0
/dev/dsk/c18t0d0
/dev/dsk/c15t0d0
/dev/dsk/c15t0d2
/dev/dsk/c27t0d0
/dev/dsk/c12t0d0
/dev/dsk/c18t0d1
/dev/dsk/c9t0d1
/dev/dsk/c6t0d1
/dev/dsk/c24t0d1
/dev/dsk/c6t0d0
/dev/dsk/c24t0d2
/dev/dsk/c18t0d2
/dev/dsk/c9t0d2
/dev/dsk/c6t0d2
/dev/dsk/c6t0d3
/dev/dsk/c9t0d3
/dev/dsk/c18t0d3
/dev/dsk/c24t0d3
/dev/dsk/c18t0d4
/dev/dsk/c6t0d4
/dev/dsk/c24t0d4
/dev/dsk/c9t0d4
/dev/dsk/c24t0d5
/dev/dsk/c18t0d5
/dev/dsk/c9t0d5
/dev/dsk/c6t0d5
/dev/dsk/c6t0d6
/dev/dsk/c9t0d6
/dev/dsk/c24t0d6
/dev/vg01x
/dev/dsk/c18t0d6

But the principal link of /dev/dsk/c18t0d6 belong to /dev/vgoracle01, and the /etc/lvmtab shows that /dev/dsk/c18t0d6 belongs to /dev/vg01x (this is no active vg)

Hayse do a vgchange -a n vg01x, then do a vgexport vg01x follow by a vgscan -av then try to vgextend the disk.

[Geoff Wild · Accepted solution]

DON'T vgactivate the vg if you are positive that disk is an alternate link for another in an existing vg!

Just vgexport it

vgexport /dev/vg01x

then try your vgextend again.

BTW - just saw you lvmtab again - why do you have so many disks in vg00?

You really shouldn't mix your OS disk(s) with Applications - you should have them is separate vg's.

Thanks Geoff

The extends works good after the vgexport /dev/vg01x

Thanks.
