mksysb failing

[liormmm]

Hello all

I made a script that should run every once a week to do a mksysb of the system and dump it somewhere else. The script works on different servers, but there are two that are giving me headaches.

This is the output of one:

Initializing mkcd log: /var/adm/ras/mkcd.log...
Verifying command parameters...
Creating image.data file...
0512-306 mkcd: 32 megabytes of memory is required
to create a mksysb on a CD or DVD device.
Current memory size is: 0 bytes.

This server has 20GB of RAM and 8gb of paging space.

This is of the other one:

Initializing mkcd log: /var/adm/ras/mkcd.log...
Verifying command parameters...
Creating image.data file...
Creating temporary file system: /mkcd/mksysb_image...
fshop_make: 0506-252 A file system with nbpi = 4096 cannot exceed 134217728 512-
byte blocks
(it continues with the nbpi table)

The only thing I could think about this one is that rootvg is 139gb, but it's only using 18gb, and I've excluded most of the bigger filesystem on /etc/exclude.rootvg

Any clues on what could be going on?

Thanks in advance!
Lior

Have you tried to backup to tape directly instead of your procedure?

Just a suggestion, instead of doing all of these scripts, why don't you install a central NIM server where you collect all your mksysbs?

I thought about the NIM server, but we are lacking a machine to do it. I am currently mounting an NFS mount from a Solaris server, and that's where I save all the mksysbs (files).
Basically what the script does is mount a directory from the Solaris server, erase whatever is old on that directory and then run a "/usr/sbin/mkcd -e -L -R -S 2>&1 > /tmp/mkcd.out"

It also runs a savevg, but that is working just fine.
