Volume Group Creation in HP_Unix and IBM AIX

HP-UNIX:

1) # ioscan -funC disk : Locate the disk you want to use for the creation of volume group.

2) # strings /etc/lvmtab : Shows the physical volumes that are part of LVM.

3) For Hp Unix Version 11:

We need to create a device file called "group" for the volume group which we are about create. The "group" file is a character based file with the major  "64" default for Hp_ux and minor number of out choice "0x010000"

# cd /dev/

# mkdir <volume group name>

# chown root:root <volume group name>

# chmod 755 <volume group name>

# cd /volumegroup name

# mknod /dev/volume group name/group c 64 0x010000

# chown root:sys group

# chmod 755 group

4) # pvcreate /dev/rdsk/c#t#d# : PV creation.

5) # vgcreate -s <PE size> /dev/<volume group name> /dev/dsk/c#t#d#

6) # vgdisplay : View the volume group created.

7) # strings /etc/lvmtab : Verify the same.

AIX:

1) # cfgmgr

2) # lspv :  Select the physical volumes in the none state.

3) # mkvg -y <volume group name> -s <PP size> <Physical volumes....>

4) # lsvg  : List all the volume group.

5) # cd /etc/vg/

6) # ls -l : Verify a "Zero Byte" file is created with the prefix "vg.<VG ID>" has been created..
