How to correct bosboot error messages in AIX ?

1. First we will assign the bosboot image to the OS to avoid bosboot error messages on the server.
bosboot command is similar to dracut command of linux.

It creates a boot file, or say boot image from our system RAM (Random Access Memory) and existing running kernel image.

ngelinux028 --> bosboot -ad /dev/ipldevice
bosboot: Boot image is 57372 512 byte blocks.

ngelinux028 --> bootlist -m normal -o
hdisk0 blv=hd5
hdisk15 blv=hd5

ngelinux028 --> getconf BOOT_DEVICE
hdisk0

2. Other useful commands to get the boot disk details.

ngelinux028 --> ipl_varyon -i

ngelinux028 -->

Now since we have changed/added the bos boot image the error messages will stop appearing on the AIX system errpt.
