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?

How would a do this savely.
This is what i have already.
1) take a system backup.

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!

net::dns::question
Net::DNS::Question(3) User Contributed Perl Documentation Net::DNS::Question(3)
NAME
Net::DNS::Question - DNS question class
SYNOPSIS
"use Net::DNS::Question"
DESCRIPTION
A "Net::DNS::Question" object represents a record in the question section of a DNS packet.
METHODS
new
$question = Net::DNS::Question->new("example.com", "MX", "IN");
Creates a question object from the domain, type, and class passed as arguments.
RFC4291 and RFC4632 IP address/prefix notation is supported for queries in in-addr.arpa and ip6.arpa subdomains.
parse
($question, $offset) = Net::DNS::Question->parse($data, $offset);
Parses a question section record at the specified location within a DNS packet. The first argument is a reference to the packet data. The
second argument is the offset within the packet where the question record begins.
Returns a Net::DNS::Question object and the offset of the next location in the packet.
Parsing is aborted if the question object cannot be created (e.g., corrupt or insufficient data).
qname, zname
print "qname = ", $question->qname, "
";
print "zname = ", $question->zname, "
";
Returns the domain name. In dynamic update packets, this field is known as "zname" and refers to the zone name.
qtype, ztype
print "qtype = ", $question->qtype, "
";
print "ztype = ", $question->ztype, "
";
Returns the record type. In dymamic update packets, this field is known as "ztype" and refers to the zone type (must be SOA).
qclass, zclass
print "qclass = ", $question->qclass, "
";
print "zclass = ", $question->zclass, "
";
Returns the record class. In dynamic update packets, this field is known as "zclass" and refers to the zone's class.
print
$question->print;
Prints the question record on the standard output.
string
print $qr->string, "
";
Returns a string representation of the question record.
data
$qdata = $question->data($packet, $offset);
Returns the question record in binary format suitable for inclusion in a DNS packet.
Arguments are a "Net::DNS::Packet" object and the offset within that packet's data where the "Net::DNS::Question" record is to be stored.
This information is necessary for using compressed domain names.
