reorgvg
hello

I have launched a reorgvg this week end, on a logical volume
Before the reorgvg, I had:
disk5
disk6
disk7
disk8

I have defined the lv with "maximum" disk, and launch the reorgvg
Now i have:
disk5
disk6
disk7
disk8
disk11
disk12
disk14

I don't understand why there are 3 another disks ??? it is a problem ?

and here the lslv -l result :
hdiskpower5 5158:000:000 27% 1427:1427:1427:877:000
hdiskpower6 927:000:000 73% 250:677:000:000:000
hdiskpower7 1145:000:000 0% 377:000:000:384:384
hdiskpower8 644:000:000 0% 000:000:000:000:644
hdiskpower11 874:000:000 0% 256:000:136:256:226
hdiskpower12 451:000:000 0% 000:000:000:131:320
hdiskpower14 176:000:000 0% 000:000:000:000:176

apparently the result of reorgvg is not good ?

thank you for your help

Hello, I'm trying to understand what is the practical usage of this command. In IBM website I've found that: Reorganizes the physical partition allocation for a volume group. In which situation should I use it? Could you give me some example. Thanks, p (1 Reply)

Cancelling Reorgvg

hi guys. Quick and simple question... Can a reorgvg (aix 5.3) be canceled and what are them impacts if any? I would guess it can be canceled and once restarted, starts back where it left off? Can't find the info in the man pages or google... Thanks. (4 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
