Backup for Easy Distribution (optional)

At this point all the resources needed to install systems are prepared andthat makes it a good moment to make a backup of the nim configuration and the volume group so that can be easily distributed to other servers. Normally this is done usig smit - but using smit and F6 (or Esc-6) I determine the command I need is:

/usr/lpp/bos.sysmgt/nim/methods/m_backup_db $FILE

so I am just going to put my backup in /export/nim/nimdb.initial.backup

# /usr/lpp/bos.sysmgt/nim/methods/m_backup_db  /export/nim/nimdb.initial.backup 
a ./etc/objrepos/nim_attr 8 blocks.
a ./etc/objrepos/ 8 blocks.
a ./etc/objrepos/nim_object 8 blocks.
a ./etc/objrepos/ 8 blocks.
a ./etc/NIM.level 1 blocks.
a ./etc/niminfo 1 blocks.
a ./etc/NIM.primary.cpuid 1 blocks.

And with that saved into /export I'll make a logical volume in the extra space I have in rootvg and put the savevg file there until I have time to transport it to a DVD.

# df -g | grep /export
