vg01 is not recognized

[Yaroki]

Hello,

I am running HP-UX B.11.11 on a C8000 (...)

The machine has 2 Disks as follow:

1. UP-UX OS LVM on /dev/vg00

2. Application that mounted on /scc on /dev/vg01

I replaced the OS disk but the system could not recognized vg01.

I rebooted the system into hpux -lm mode and run these commands:

vgexport vg01

mkdir /dev/vg01

mknod /dev/vg01/group c 64 0x010000

vgimport vg01

vgchange -a y vg01

vgcfgback -u /dev/v01

reboot

Still the same error appeared.

strings /etc/lvtab - indicates that vg00 and vg01 are there.

SAM show that v01 is marked "unused"

How can I assign/import vg01 to the system?

Please advice.

Yaron

What's the error?

After you did the 'vgimport' above did the VG activate correctly?  Did you do a 'vgdisplay -v vg01' to see that all of the LVs that are supposed to be in that VG are present?

The steps you took above will do that.  However, without any actuall error messages it's hard to say what is wrong.

When you run vgimport, you did not specify the disk you imported.

vgimport vg01 /dev/dsk/<diskctd>
