Steve, I am not very familiar with the HACMP implementation. However, I
forwarded your questions to one of the developers who worked on HACMP, and
I have imbedded his answers below (between the "START" and "END" OF

The CLUSTERNODE option must therefore imply that the host name is not

Not really..the pswd file will still not work on any arbitrary
system...only on machines within the cluster.

Does the AIX 4.3.3 support require HACMP?

Yes, HACMP 4.4 or later is required.

Should it work with other HA software even if not supported?

No, we depend on certain HACMP APIs.

When can we expect Sun/Veritas support?

This is a well known requirement, but we don't have a target delivery date
yet.

Will it run on older server levels?

I don't know of any dependency on a TSM 5.1 server. It should work with
TSM V4 servers as well.

Sorry Andy, its must seem that it doesn't matter what you give us we want

Don't entertainers have a saying?.... something like, "Always leave 'em
begging for more!" :-)
I am not 100% certain about the answer to the last question regarding a
TSM 5.1 dependency.... if it turns out that there is a dependency, I will
be sure to follow up with another post.

The only dumb question is the one that goes unasked.
The command line is your friend.
"Good enough" is the enemy of excellence.

Subject: 5.1 Client cluster support
Hi All,
I'm intrigued by the possibilities of the new 5.1 Client cluster support
for unix (this is probably old hat to Windows people).
We have a new passwddir option which allows us to place the TSM encrypted
password wherever we like e.g. a shared disk.
The CLUSTERNODE option must therefore imply that the host name is is not
combined with the password when it is encrypted (? security hole)
We then run with manageservices schedule so the CAD process runs dsmsched
on the correct machine at the time of the schedule.
The client install guide states that this is only supported under AIX
4.3.3 and it implies HACMP.
The only hook that I can see that might be HACMP specific is to discover
which filesystems are cluster controlled and I can see no reason why this
client would need 5.1 server function.
I have Sun/Veritas clients that need this badly, and I'm looking at
AIX/Veritas for some upcoming work.
Does the AIX 4.3.3 support require HACMP? Should it work with other HA
software even if not supported?
When can we expect Sun/Veritas support?
Will it run on older server levels?
Sorry Andy, its must seem that it doesn't matter what you give us we want
more, but any clues on this will be appreciated.
Thanks
