Using network boot images for AIX 4.3 or later SPOTs

Edit online

You can use network boot images for AIX® 4.3 or later to reduce the amount of disk space used and the time required to create boot images from SPOT resources.

In AIX 4.3 or later, by default NIM only creates the boot images required to support the machines and network types that are defined in the environment. This situation should significantly reduce the amount of disk space used, and the time required to create boot images from SPOT resources.

Note: Due to kernel changes, AIX 5.2 or later, does not provide NIM support to create or use AIX 4.2 or earlier SPOTs.

In AIX 5.3 with 5300-03 or later, to create SPOT resources for AIX 4.3.3, the environment variable INST_DEBUG must be set as shown:

export INST_DEBUG=yes

If the INST_DEBUG variable is not set, NIM cannot create SPOT resources for AIX 4.3.3.
