All
Just wanted to share with you my experience of the in
place upgrade for NBU 5.1 MP7 to 6.5.2
Original Plan: Upgrade Master only,
then do SAN Media Servers at a later date.
However, due to issues with one Media
Server and the nbpushdata command having problems communicating with one Media
Server (Even though NBCC worked like a charm!), an issue had arisen that
required Symantec Help!
In the end, it was easier to do an
inplace upgrade for everything (Did not make me popular but its done!) and so
far its gone ok-ish!
Main problem was 1 Media Server was
offline, refused to do restores or backups. Turned out it was only Active for
disks. Problem tied down to a corrupt ltid and oprd processes. These got
repaired by a manual replacement of the files. No idea why it happened, as the
box in question installed and upgraded flawlessly!
One major problem I have seen is with
my Win2k3 Active/Passive Mail Cluster. Now reading some notes, its clear
something has changed in terms of how 6.5 handles Virtual Server Names, but if
anyone can shed any light on this, it would be appreciated.
The 5.1 Topology used to show the
NODE1 and NODE2 as physical SSO SAN MEDIA SERVERS. I used the command BPSTUADD
to create a Virtual Storage Unit called MAIL. This used to appear in the
topology of Activity Monitor.
Now, it appears, when I run the
backup, the topology shows the Virtual Name MAIL as a Computer Icon. As if it
is doing the backups over the LAN. Worse still, the throughput is showing
speeds as if it is LAN Based Backups !!
Not sure why this has happened, but
if anyone has a Mail System in a 2-node cluster and was on 5.1 and now moved
to 6.5, I would be interested to hear how yours is working!
Thanks !
Regards
Simon
