Display the number of free physical partitions

1. Determine the logical volume associated with the paging space or file system:

   For a paging space:

   lsps -t lv


   For non-paging file systems:

   df -k

2. Determine the volume group associated with the logical volume: lslv hd#


   Don't include the /dev/ prefix.

   The number of 1024-blocks will be the number of LPs times the PP SIZE times 1024.

3. Determine if there are enough free physical partitions in the volume group to increase space. lsvg vgname


   For mirrored drives, the number of FREE PPs must be at least the number of logical partitions to be added times the number of COPIES in the lslv command.

   The number of USED PPs in the lsvg output will be 4 more than the sum of the allocated PPs shown in the output of the lslv commands for all of the logical volumes allocated from the volume group.

To change the size of a paging space, use the chps command or the smit pgsp FastPath.

Increase the size of a paging space

Increases the size by nn logical paritions.

Decrease the size of a paging space

Decreases the size by nn logical paritions.

To change the size of a file system, use the chfs command or the smit manfs FastPath.

Increase or decrease the size of a file system by one logical partition

Although size=+1 says to increase the size by one 512-byte block, the size will be rounded up to the actual size of a logical partition.

Increase the size by a given amount

Change the size to match another file system

The df command will display the number of 512-byte blocks in the first file system. Using that number in the chfs command will change the second file system to the same size.
