BMR on AIX 5.3 : SRT Media Boot iso too large

[olivier427]

Hi,

I have just created a boot media image for an AIX 5.3 system using the bmrsrtadm command.

The image was generated properly but it is way too large to fit on a CDROM !

ls -l
-rw-r--r--   1 root     system   1506795520 Jul 29 17:04 srt_20100716_AIX_CDROM.iso  (That is 1,5 Go)

Unfortunately my AIX systems only have CDROM drives, no DVD.


Is there a way to tell bmrsrtadm to generate an iso image with a maximum size of 650 MB ?

(I'm using Netbackup 6.5.6)

Thanks,

Olivier

No. That is not possible. User can not decide on the size of SRT.
And in AIX case, BMR SRT is considerably big in size compare to other UNIX SRTs.

You could delete come contents in SRT that you used to create ISO. Like in case you have patched NBU client version in SRT, then you can delete /usr/openv/pack folder which can help reducing SRT size by ~300 MB.
But still it wont fit into CD because the AIX mini-os footprint in the SRT itself is big in size.

I am not sure if you can use the ISO as virtual CD/DVD in your environment and media boot the client over it.
Else BMR NW boot is another option to start restore.

Thanks.

Thanks for your quick reply.

I'll consider using BMR network boot instead.
