Mount disk HP-UX 10.20

Sy-hoang Truong_1 — Fri, 03 Mar 2000 02:20:38 GMT

Hello,
I'd like to mount a disk unused seagate 8678Mb by increasing to a volume group
existing. I get a message : "This system is part of a high availability
cluster.The disk you have selected contains LVM structures which could indicate
the disk is being used by another system in the cluster. Serious problems can
occur if this disk is currently used by another system in the high availability
cluster.
Do you want to continue to add this disk?
Yes- No"
What's happen if I reply yes?
Thanks

The messages indicate that this disk was at some time configured as part of a
volume group. Your kernel can verify that the disk is not allocated to any
volume groups on itself, but it cannot check the kernels on teh other system(s)
in your HA configuration. So it is warning you that the disk might be shared
and in use by another server. If you are certain that the disk is unused, then
you may add it to your VG without causing any problems.

The warning message was detected because the new physical volume you are adding
has existing LIF header information from the previous volume group.

You can verify usage with:
strings /etc/lvmtab | grep "device name" ( for cooked disk only) then use SAM
or pvcreate with the -f option.
