Thank you for your replies. Actually, I am more concerned about the SPOT than the lpp_source, since I use my NIM server to recover an AIX server if the rootvg were to crap out, and in our annual disaster recovery test. Here's the specific scenario I'm concerned with right now:
1. All my servers are running 5.3.0.11. I have an lpp_source and a SPOT which exactly match this AIX level. I also take regular mksysb's to the NIM master, so that in a disaster situation, I can recover my NIM master from a mksysb DVD and backups, and then be ready to recover all other AIX servers from mksysb's on the NIM master.
2. I want to update them all to the latest 5.3.0.12. This is no big deal, since I have downloaded the required patches, and I can simply do a "smitty update_all" on each of them, if I want, and not even worry about the NIM.
3. After the 5.3.0.12 upgrade is done, I want to still be able to install/recover any AIX server from the NIM master, by using the SPOT and mksysb backup there.
QUESTION: How do I best accomplish number (3)?
The advice I have from a Known Good AIX Person (KGAP) is that the SPOT must be of a version NO OLDER than the mksysb I want to recover with it. According to the KGAP, I should NOT try to update my SPOT, but should order a full installable version of AIX to match what all my servers are running, and build an lpp_source and SPOT from that. This seems terribly slow and inefficient, and I am hoping there's a better way. I'd hate to have to order a full AIX DVD set every time I upgrade from 5.3.0.n to 5.3.0.(n+1). So, tell me, please: How do you keep your SPOT in sync with all your AIX servers?

I'm trying to understand the requirements for AIX version matching between a SPOT, LPP_SOURCE and my mksysb images. I have a NIM server installed, and I've used it to install new LPARs both from the LPP_SOURCE and from mksysb files. These were based off 7100-00-01.

Friend's,
I was playing around with NIM in my environment & had a quick question in mind which I didn't/couldn't find answer to, which is -- how to find the name of the NIM server sitting on the NIM client?
All leads to the answer would be much appreciated, many thanks!

kproplog
KPROPLOG(8) MIT Kerberos KPROPLOG(8)
NAME
kproplog - display the contents of the Kerberos principal update log
SYNOPSIS
kproplog [-h] [-e num] [-v] kproplog [-R]
DESCRIPTION
The kproplog command displays the contents of the KDC database update log to standard output. It can be used to keep track of incremental
updates to the principal database. The update log file contains the update log maintained by the kadmind(8) process on the master KDC
server and the kpropd(8) process on the slave KDC servers. When updates occur, they are logged to this file. Subsequently any KDC slave
configured for incremental updates will request the current data from the master KDC and update their log file with any updates returned.
The kproplog command requires read access to the update log file. It will display update entries only for the KDC it runs on.
If no options are specified, kproplog displays a summary of the update log. If invoked on the master, kproplog also displays all of the
update entries. If invoked on a slave KDC server, kproplog displays only a summary of the updates, which includes the serial number of the
last update received and the associated time stamp of the last update.
OPTIONS
-R Reset the update log. This forces full resynchronization. If used on a slave then that slave will request a full resync. If used
on the master then all slaves will request full resyncs.
-h Display a summary of the update log. This information includes the database version number, state of the database, the number of
updates in the log, the time stamp of the first and last update, and the version number of the first and last update entry.
-e num Display the last num update entries in the log. This is useful when debugging synchronization between KDC servers.
-v Display individual attributes per update. An example of the output generated for one entry:
Update Entry
Update serial # : 4
Update operation : Add
Update principal : test@EXAMPLE.COM
Update size : 424
Update committed : True
Update time stamp : Fri Feb 20 23:37:42 2004
