LUN / Diskgroup info
Hi,

I was just about to decommission a box when a weird question paused the operation. This box has veritas volume manager installed. I was umounting all the vx volumes and deleting the disk groups so that the storage admin can take back the LUNS. Now this is where i am stuck - i see a disk belonging to a disk group that has been deported to some other server that i dont know of.

bash-2.05# vxdisk -o alldgs list
DEVICE TYPE DISK GROUP STATUS
GENESIS0_0 auto:sliced - - online
GENESIS0_1 auto:sliced - - online
GENESIS0_2 auto:sliced - (lecstardg) online
GENESIS0_3 auto:sliced - - online
c1t0d0s2 auto:none - - online invalid
c1t1d0s2 auto:none - - online invalid
c1t2d0s2 auto:none - - online invalid
c1t3d0s2 auto:none - - online invalid

I cannot possibly just import the dg and screw up some other server and neither can i find out which host has imported lecstardg with my present knowledge. Is there anyway that i can get to know which server has imported it? Any help is really appreciated

Thanks,
Sage

vgscan

VGSCAN(8)						      System Manager's Manual							 VGSCAN(8)

NAME

       vgscan - scan all disks for volume groups and build /etc/lvmtab and /etc/lvmtab.d/* which are the database for all other lvm commands.

SYNOPSIS

       vgscan [-d|--debug] [-f|--forcenumbers] [-h|--help] [-r|--remove_snapshots [VolumeGroupName]] [-v|--verbose]

DESCRIPTION

       vgscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of other disk devives in the system for volume groups defined.

   OPTIONS
       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -f, --forcenumbers
	      If  used	volume group and/or logical volume minor numbers are found during scan, replace them. This will potentially cause problems
	      for NFS exported filesystems on logical volumes with changed numbers.

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -r, --remove_snapshots [VolumeGroupName]
	      Remove all snapshot logical volumes from all or just the named volume group.

       -v, --verbose
	      Display verbose information of vgscan's activities.

Hint
       Put vgscan in one of your system startup scripts.  This gives you an actual logical volume manager database before  activating  all  volume
       groups by doing a "vgchange -ay".

DIAGNOSTICS

       vgscan returns an exit code of 0 for success and > 0 for error:

       1  error reading physical volumes
       2  error inserting vokume group name into lvmtab
       3  no volume group(s) found
       4  error creating lvmtab
       5  no or not enough free device specials to store volume group in lvmtab
       6  error storing VGDA on disk(s)
       7  reused LV device number
       8  error releasing snapshot logical volume

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       99 invalid command line
