[Info-vax] SmartArray 5300A question

Tue Aug 16 08:23:47 EDT 2011

Rich,

Yeah, getting ACU-XE going is not for the faint of heart. The first time
around, we had an issue with Multinet (I believe we were running the beta
5.3), but the Multinet engineers jumped on it, and working together with an
HP engineer, they solved the problem (some TCPIP port or other caused some
grief, can not remember it anymore).

I know the installation included:
finding the latest version of TCPIP services, and taking some pieces from
that -- has to be the right service kit to match what would run with that
version of VMS. There were some weird things that needed to go into the
snmpd.conf file, too.

But, eventually I got it all going. I'm not surprised that it would not move
gracefully from one system disk to another; I've had issues with that as
well. everything has to be in the sys$specific root.

Here are log files on an 8.3 system; sometimes you can figure out what
happened by reading them...

Best,

Carl
