Re: vgdisplay error
ls -ld /dev/vgbssb
ls -l /dev/vgbssb
It will help us to see problems concerning files/dirs rights and definitions.
Regards,
Fred

Re: vgdisplay error
It seems that someone has deleted the group file that holds information about ur volume group and lv... nothing to worry about pls follow the below instruction and recreate a group file and everything should work fine.
#mknod /dev/vgbssb/group c 64 0x050000
#vgchange -a y vgbssb
#vgdisplay -v vgbssb
Best Regards,
Prashanth

Re: vgdisplay error
To determine what was the minor number 0x0x0000 of your group you may run the below command..
#ll /dev/vgbssb
Example:
# ll /dev/vg02
total 0
brw-r----- 1 root sys 64 0x050001 Jun 26 23:37 lvol1
crw-r----- 1 root sys 64 0x050001 Jun 26 23:37 rlvol1
Here Minor number of lvol is 0x050001 so you use minor number for group as 0x050000
Best Regds,
Prashanth
