Change corrupted harddisk in LVM

[Mike_108]

I have L2000/800/9000 server with HPUX 11.0
the problem is one of the disk in one of the volume group is corrupted. this disk cannot be access. i try to cahnge the disk by booting in "hpux -lm" then try to activate that volume group but system cannot activate that volume group.
so, i cannot remove this volume group or do something else...
could anyone give a solution for this problem.

Is the disk part of your /dev/vg00 group ? Does the volume group use mirroring?

If you dont have any importatnt date in this volume group or disk then try removing all logical volume from this disk by lvremove command and then do vgreduce -f to remove the missing PV in this volume group.
Look at man pages or vgreduce for more help.

no, this vg is not under vg00
actually this vg is for database. there is 6 vg; datavg01, datavg02, datavg03, datavg04, datavg05, and datavg06.and all the vg with only one lV that is lvol01 and mounted on /disk1, /disk2, /disk3 and so on.
the problem is on the datavg04, where i can't even issue a command such as bdf to view the saiz or something else which is accessing that disk. if so, the process will hang just like that.

because of this, any lvm command i can't issued to remove or something else.

hope this info will help you all to help me...
thanks..

Boot the system in single user mode and reduce that volume group. By vgreduce -f vg_name you can remove all PV which are not accessible. Copy the /etc/lvmtab and remove this then do vgscan to rebuild the /etc/lvmtab

this wasy you should be able to remove that volume group.
