Applied and commit state

In applied state if WANT to do any changes on installed software then we can do

But in commit the changes are not ALLOWED to do. Once did installation.

A COMMITTED FILESET update cannot be rejected.

OUTPUT from the installp -s command, which is used to get a list of applied software fileset updates and updates that are available to be either committed or rejected.

VGDA: Volume GROUP Descriptor Area. It contains the information about volume group to which the PHYSICAL volume belongs to. It also contains the information about physical partitions, logical partitions and logical VOLUMES.

VGSA: Volume Group Status Area it contains the information about physical partition from all physical volumes of the same volume group. It contains the status of VG.

To TRULY change the kernel to 64-bit from 32-bit, the SYSTEM must be at the AIX® 5.1 or AIX 5.2levels.

# bootinfo –y

It shows a kernel is either 32-bit or 64-bit.

To truly change the kernel to 64-bit from 32-bit, the system must be at the AIX® 5.1 or AIX 5.2levels.

# bootinfo –y

It shows a kernel is either 32-bit or 64-bit.

To change to a 64-bit kernel, enter the FOLLOWING commands:

# ln -SF /usr/lib/boot/unix_64 /unix

# ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix

# lslv -m hd5

# bosboot -ad /dev/ipldevice

# shutdown -Fr

# ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix

# lslv -m hd5

# bosboot -ad /dev/ipldevice

# shutdown -Fr

1. Modify the /usr/lib/boot/unix directory and the /unix directory to be a symbolic link to the binary for the desired KERNEL.
2. Run the bosboot command to write a new system boot image.
3. Reboot the system.

The PATH name of the 64-bit kernel is /usr/lib/boot/unix_64, and the path name of the MULTIPROCESSOR VERSIONS of the 32-bit kernel is

/usr/lib/boot/unix_mp.

T – factor means that it will change the PP size to increase the EFFICIENCY of VG

#chvg –t16 datavg

Cal-if suppose that datavg pp size is 1016 we can TAKE t factor is 16 then it COMES to 2048 and pv contains in vg is 2.

T – factor means that it will change the pp size to increase the efficiency of vg

#chvg –t16 datavg

Cal-if suppose that datavg pp size is 1016 we can take t factor is 16 then it comes to 2048 and pv contains in vg is 2.

PP size can be CHANGED using a T-factor. If not then add a partitions in VG by ADDING one disk.

# chvg –t3 rootvg

PP size can be changed using a T-factor. If not then add a partitions in VG by adding one disk.

# chvg –t3 rootvg

First check the blv record USING,

# bootlist –m NORMAL –o
Remove the old blv record, using
# chpv –c hdisk2
# bootlist –m normal hdisk1
# bootlist –m normal hdisk2

# unmirrorvg rootvg hdisk2
# reducevg rootvg hdisk2
#LSVG –p rootvg

# unmirrorvg rootvg hdisk2
# reducevg rootvg hdisk2
#lsvg –p rootvg
# lspv
# bootlist –m normal –o

Check disk size belong to vg , take two same size disk to mirror

# bootinfo –s hdisk2
#lsvg –p rootvg

Add ONE more disk of same size of already have disk having rootvg.

# extendvg rootvg hdisk2
# lsvg –p rootvg

Now mirror vg with background sync LV. It sync LVs in background with new LVs

# mirrorvg –s rootvg
Create a boot image
# bosboot –ad /dev/hdisk2
#bosboot –ad /dev/hdisk1

Add a blv

record of NEWLY ADDED disk, first check and then add.

# bootlist –m normal -o
#bootlist –m normal hdisk2 hdisk1

Check disk size belong to vg , take two same size disk to mirror

# bootinfo –s hdisk2
#lsvg –p rootvg

Add one more disk of same size of already have disk having rootvg.

# extendvg rootvg hdisk2

Now mirror vg with background sync LV. It sync LVs in background with new LVs

# mirrorvg –s rootvg
Create a boot image
