This small document will helps you how to create volume groups (VG) after mapping host from storage.
Step-1 : Run "cfmgr" after mapping host in storage
e.g.,
# cfgmgr
Note: select "yes" if you want to create volume group forcefully.
If you want to remove one exiting file system, then you need to use "rmfs". So that you can create new vg and file system. But before that you need to clear the volume group.
Step-1 : Run "cfmgr" after mapping host in storage
e.g.,
# cfgmgr
Step-2 : List attached disks, use “lspv” (
physical volume)
#
lspv
hdisk0 00f9d98b1cc32587 rootvg active
hdisk1 none None
hdisk2 none None
hdisk3 none None
#
Here, after disk name "none" is coming means, physical volume is not created. So you need to create pvs.
Step-3 : Verify the size of attached disks
# bootinfo
-s hdisk1
102400
# bootinfo
-s hdisk2
1048576
# bootinfo
-s hdisk3
512000
#
Step-4: create volume group (vg)
a) Enable pv, It will create pvid :
# chdev -l
hdisk1 -a pv=yes
hdisk1
changed
# chdev -l
hdisk2 -a pv=yes
hdisk2
changed
# chdev -l
hdisk3 -a pv=yes
hdisk3
changed
#
bash-4.2#
lspv
hdisk0 00f9d98b1cc32587 rootvg active
hdisk1 00f9d98bc23769cf None
hdisk2 00f9d98bc2381d77 None
hdisk3 00f9d98bc238343f None
bash-4.2#
c) Now create Volume group:
# smit mkvg à Add an Original Volume group à Enter Volume group
name ( e.g., binvg) à
Now select required / planned PV Name ( as seen below) à
à
e.g., select “hdisk1”. See below screen shot
à
Now run set info (press two times enter) à
Exit ( Esc + 0)
Now confirm, whether PV created or not.
# lsvg
rootvg
binvg
#
# lspv
hdisk0
00f9d98b1cc32587
rootvg active
hdisk1 00f9d98bc23769cf binvg active
hdisk2
00f9d98bc2381d77
None
hdisk3
00f9d98bc238343f
None
#
( Initially “None” when not assigned to any VG).
Step-5: create File system
# smitty crfs
Select “Add
an Enhanced Journal File system” à
select “ Add an Enhanced Journal File system” again ( to automatically create
logical volume (LV) à
select your VG ( eg, binvg) à
à select Unit ( as GB) .
Use Esc+4 to list info à
Enter Required size ( use max -2 GB aprx from actual VG size) à Enter Mount point Name à Select
restartable option as “Yes” (see from
below screen shot) – Press Enter to Apply
After hit
“Enter” key
Step-6 : Now mount it

Add more disk to exting VG:
If you want to add more disks to existing volume group, then you need to extend volume group.
Extend VG (
add more disk to exting vg):
e.g.,
# smit
extendvg
To remove exting file system:
#rmfs /u01
To Clear Volume Group ( vg):
e.g.,
# chdev -l hdisk4 -a pv=clear
To view what storage attached:
Use "lsdev" command to view storage attached with passing "disk" as a parameter.
bash-4.2$ lsdev -Cc disk

fslv03 jfs2 750 750 1 open/syncd /u02
To find WWN number to map host in Storage:
a) AIX
# lscfg -vl fcs*| grep "Network Address"
b) LINUX
# systool -c fc_host -v | grep port_name
c) Window Server
Open Solution Manager, Then run below command in solution manager console
c:\> Get-WmiObject -class MSFC_FCAdapterHBAAttributes -namespace “root\WMI” | ForEach-Object {(($_.NodeWWN) | ForEach-Object {“{0:x}” -f $_}) -join “:”}

Scenario analysis:
-- During some maintenance activity, one of VG ( e.g., "binvg" deactivated.), I tried to tried to create with new vg name ( eg. binvg2) but while creating file system with mount option, it doesn't allow to proceed. Because already file system exits on that. I tried with "rmfs" to remove file system which was not worked. These are wrong attempts:
Now from this situation we will bring the existing "binvg".
