those LUNs seems to be HP EVA storage LUNs.
if you have the evainfo utility installed, you can do:
Code:
ioscan
insf -e -C disk
evainfo -a > evainfo
grep -i 6005-08b4-0001-529c-0005-6000-45d6-0000 evainfo --> should get a DSF (/dev/rdsk/c1t1d1)
strings /etc/lvmtab and search there for that DSF.
On top of it you should have the VG that is using that disk.
If you dont find it in lvmtab, then that disk is not used in any VG on your system.

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

Does anyone have any simple methods for moving a current logical volume from one volume group to another? I do not wish to move the data from one physical volume to another. Basically, I want to "relink" the logical volume to exist in a different volume group. Any ideas? (2 Replies)

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
