how to completely remove a drive

[Steven Chen_1]

Hi,

By completely removing a drive, I'd do the followings:

umount /dev/vg07/lvol1
vgchange -a n /dev/vg07
vgexport /dev/vg07

Please tell me if I have done enough to get it clean, so that I don't have problem on the next reboot and add a new drive.

All help is appreciated.

Steven

HI steven

With the above command the information about the Volume group vgo7 is removed from the server.ie Now the server now doesn't know that there was a VG with vg07 existed in the server. But i am not sure whether this is what u require. "Adding a new drive, removing a drive" --are u refering to disk? What exactly u require on the next reboot..

Regards

umount
lvremove
vgreduce disks in vg
vgremove
delete fstab entry
rmsf the device files
Note the way hpux assigns channels this will not reclaim them.

Depending on the type of drive and enclosure you might not even have to reboot. What problem are you having with your current drive?

Hi Steven

If you want to do a drive replacement with existing LVM structure then

#umount all the parttions in /dev/vg07
#vgchange -a n /dev/vg07
#vgcfgbackup /dev/vg07
#vgexport /dev/vg07
Replace the new disk
#vgcfgrestore
#vgchange -a y /dev/vg07
#mount the filesystems

You need to restore the data from the backup
