What's the meaning of this parameter no_nim_client?

I know it's by default = NO, but some BOSINST like VIOservers you have to set to = YES.
What exactly does it do. once you reboot the first time the installed AIX?

    means that the machine will remain a nim client after installation, including particularly the installation and configuration of bos.sysmgt.nim.client, /etc/niminfo etc.


    means that the nim client filesets are not installed/configured, so at last after reboot the client will no longer be part of NIM and the master will not be able to communicate wth it.

    ok... but why on the power vm best practices says when you are going to restore a vios from NIM:

    nim -o define -t mksysb \
    -a server=master \
    -a location=/export/vios_backup/vios22.mksysb vios22_mksysb
    # nim -o define -t spot \
    -a server=master \
    -a location=/export/vios_backup/spot \
    -a source=vios22_mksysb vios22_spot
    # nim -o bos_inst \
    -a source=mksysb \
    -a mksysb=vios22_mksysb \
    -a spot=vios22_spot \
    -a installp_flags=-agX \
    -a no_nim_client=yes \
    -a boot_client=no \
    -a accept_licenses=yes vios22

    Is it for to not change the SEA? Or network  parameters? Also, what means "-a boot_client=no"?

    Certainly not because of SEA or network issues.

    I think they mean that a VIOS should only be treated as a standard NIM client during an initial cloning installation, later it should use the builtin "backupios" facility for backup, NIMoL ("installios") via HMC for a full restore and "updateios" (maybe via dsm, remember?) for updates.

    It might be that because an OS update doesn't work with standard NIM tools they come to the conclusion that there's no need for a VIOS to remain a NIM client all the time.


    means that the NIM server should not try to initiate a client reboot over the net.
