Increasing paging space on AIX for WebSphere Network Deployment installation

Insufficient paging space can cause the WebSphere® Application Server Network Deployment on AIX® to fail.

Problem: A lack of available paging space can cause a WebSphere Application Server Network Deployment on AIX to fail.
When WebSphere Application Server on AIX fails, this error is displayed /opt/IBM/WebSphere/AppServer/bin/versionInfo.sh" error=12, Not enough space

Solution

Check the paging size by entering this command:

# lsps -a

Page Space      Physical Volume   Volume Group    Size   %Used Active Auto  Type Chksum
hd6             hdisk0            rootvg         2560MB    13   yes   yes    lv     0

Enter this command to increase swap size:

# chps -s 8 hd6

If the command fails this error is displayed:

0516-404 allocp: This system cannot fulfill the allocation request. 
There are not enough free partitions or not enough physical volumes to keep 
strictness and satisfy allocation requests. The command should be retried with 
different allocation characteristics.

chps: Cannot change paging space hd6.

Correct the problem by decreasing the size of another volume in rootvg to free up space for hd6.
For example, enter this command:
chfs -a size=-10G / (or other mountpoint with free space)
```
Page Space      Physical Volume   Volume Group  Size    %Used Active Auto  Type Chksum
hd6             hdisk0            rootvg        2560MB    13   yes   yes    lv     0
```
