vgdisplay(1M)

Message Text
vgdisplay: Couldn't query volume group "/dev/vgname".
Possible error in the Volume Group minor number;
Please check and make sure the group minor number is unique.
vgdisplay: Cannot display volume group "/dev/vgname".
Cause
This error has the following possible causes:
1. There are multiple LVM group files with the same minor number.
2. Serviceguard was previously installed on the system and the /dev/slvmvg device file still
exists.
Recommended Action
1. List the LVM group files. If there are any duplicate minor numbers, export one of the affected
volume groups, optionally create a new group file with a unique minor number, and reimport
the volume group. If you are not familiar with this procedure, contact your HP support
representative for assistance.

# mkdir /dev/vgname
# mknod /dev/vgname/group c 64 unique_minor_number
# vgimport -m vgname.map -v -f vgname.file /dev/vgname
2. Remove the /dev/slvmvg device file and re-create the /etc/lvmtab and /etc/lvmtab_p
files using the following commands:
# rm /dev/slvmvg
# mv /etc/lvmtab /etc/lvmtab.old
# mv /etc/lvmtab_p /etc/lvmtab_p.old
