Disk Remove problems

[Basheer_2]

I posted a question to remove a disk from I-40 server and add to E-55 server.
Followed instructions from those replies.
This is how I did
1) removed all logical volumes from the vg. This vg had 3 disks.
2) removed volume group. made sure that vg and its PV are no longer displayed in vgdisplay.
3) Removed the disk on-line from I-40 Server anded to E-55 Server. E55 server displayed a disk is added.

After a re-boot of I-40 Server, I keep getting
Disk at 32.1.0 is not responding, check power, cables. I can't telnet anymore.

What can I do to fix this probelm.

Hi,

Does the disk device still show up in an 'ioscan'? You could try 'rmsf -H 32.1.0' and see if it will remove the disk device for the missing disk.

Did you use pvremove after removing VG and LV info?

I think system still looks LVM data structure..
man pvremove for more..

Try booting without the new disk, if you can.
I saw similar problem due to patches.

Problem might be in the VG configuration. The VG might be still there in /etc/lvmtab file and while booting the system will try to activate all VGs. Boot in single user mode by interrupting the boot process and do:

# vgexport /dev/vg_name

Reboot the system then. Make sure that the VG or any other removed disk is not specified in lvmtab or in /etc/fstab (raw device mount).

You must have missed some steps while you're removing the VG from the I-40. Does the VG still appears in /etc/lvmtab file ? Do ..
# strings /etc/lvmtab
If it does the removal is not complete. What you can do is export it and that should remove the VG and all its device files.
# vgexport /dev/vgXX
Since you can't telnet to the box you would need to do the above in single-user mode. Boot up as ..
