System does not see new drive

[Randy Daniel]

I have a HP9000/L1000 that had a hard drive go bad. The drive was mirrored so I am still up an running. I replaced the bad drive with a new drive but I can not get vgsync to resync the mirrors. What are the steps to correctly replace and resync a drive? Thanks.

Shalom,

The most important step is to run pvcreate on it.

You may need this command as well.

ioscan
insf -C disk

This should get the drive recognized.

Then pvcreate, get it into the correct volume group and restore the lost structure.

Hi,

Do not run pvcreate. The procedure varies a bit on whether or not this is a boot disk mirror.

If it is not a boot disk then:

Let's assume the replacement disk is c1t5d0 and the VG is /dev/vg01.


vgcfgrestore -n /dev/vg01 /dev/rdsk/c1t5d0
vgchange -a y /dev/vg01
vgsync /dev/vg01


If it is a boot disk then:
vgcfgrestore -n /dev/vg00 /dev/rdsk/c1t5d0
vgchange -a y /dev/vg00
mkboot /dev/rdsk/c1t5d0
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c1t5d0
lvlnboot -R
vgsync /dev/vg00

Hey Randy,

It looks like Steven and Clay answer your question.

Do the pvcreate on the drive then make sure its mirrored and a bootable disk. The commands are given above.

Good Luck,

I have taken 1 step forward and 2 back. Believe it or not I replaced a bad drive with a "new" drive that was bad, so that slowed me down a bit. Now I have "new" drive installed that appears to be good according to diskinfo. Now when I try to extend vg01 to include the "new" drive I get "No device file were found in /dev". How can that be possible if diskinfo can see the device and the device can be seen by sam. Thanks again.

Why in the wide world of sports are you running vgextend? Do a "strings /etc/lvmtab". Is your disk included in vg01? If so then all you need to do is vgcfgrestore, vgchange, and vgsync.
