Quick Commands:
lslv <logical volume> [-l,
m]
Lists information about the
logical volumes. The -l option lists the disks in the logical
volume.
lspv <physical volume>
[-l, M, p]
Lists the disks on the server,
including the physical volume will give details about that disk.
The -l option will list the details of how the filesystems are
distributed on the disk.
lsvg <volume group> [-l]
Lists the volume groups on the
server, including the volume group name will give details about that
vg.
The -l option will list the logical volumes in the volume group.
lsvpcfg
Lists each vpath and the hdisks
that make up the vpath
exportvg <volume
group>
removes a volume group from a
machine
extendvg <volume group>
<physical volume>
Adds a new physical volume to an
existing volume group
importvg -y <volume group>
<physical volume>
add a
volume group to another machine
reducevg <volume group>
<physical volume>
Removes a physical volume from
a
volume group
lsdev -C -c disk
lists available disks (and the hdisk#) on the server
lscfg -vl hdisk
Shows advanced information on a disk
rmdev -dl hdisk#
remove a disk
Sample Procedures:
Check to see if all of the
logical volumes in a volume group are
mirrored
- lsvg -l <vg_name>
Procedure to find disks/vpaths that
are unallocated
- lspv|grep None
- This will show pvs and whether they are asssociated with a
volume group - Note: For vpaths, the hdisks will show as none, but they
may be allocated to a vpath – you must grep each hdisk with the lsvpcfg
- This will show pvs and whether they are asssociated with a
Procedure to make a new lun available
to AIX
- Allocate the new lun on the SAN
- Run "cfgmgr"
- Verify the new vpatch/hdisk by running "lsvpcfg"
- There should be a new vpath and it should be available with no
volume group – if not, rerun cfgmgr
- There should be a new vpath and it should be available with no
