disk issue

Hi, I have a AIX 4.3 box here with problems cause of a disk in below VG.
volume group: workvg
lspv
hdisk4 000166789869ab2d workvg
hdisk5 000166789869b96b workvg

now hdisk4 disk has failed and cause the quorum was set, workvg became varied off.
I have to replace the disk. i tried below to see if hdisk4 and hdisk5 were mirrored but got below errors
lsvg -l workvg
0516-010 : Volume group must be varied on; use varyonvg command.
varyonvg workvg
PV Status: hdisk4 000166789869ab2d PVNOTFND
hdisk5 000166789869b96b PVINVG
0516-052 varyonvg: Volume group cannot be varied on without a
quorum. More physical volumes in the group must be active.
Run diagnostics on inactive PVs.

chvg Qn workvg
0516-306 getlvodm: Unable to find Qn in the Device
Configuration Database.
0516-732 chvg: Unable to change volume group Qn.
0516-1260 chvg: Device configuration database has been updated with new information.
Since the volume group workvg is not varied on, if the workvg is of Big
Volume group type, chvg command must be run with the volume group varied
on for these attributes to be saved across exportvg/importvg operation.

Since /u01 filesystem oracle resides on this VG, can someone tell me how should i go about replacing the disk

THANK YOU!

Since the volume group has quorum on you will have to do a forced varyon to force the volume group online with out a quorum. Do a "varyonvg -f workvg" which will activate the volume group. And the chvg command has a syntax error in it - it should be "chvg -Qn workvg" - you missed out the "-" .

Thanks for ur reply.

forced varyon worked and was able to get into the volume group and remove the disk from the VG

Thanks!!
