Geoff,

Clients: NT4 SP6 and Win2k SP2/3 - TSM client 5.1.1.0
TSM Server: Win2k SP3 - V5.1.1.0

FWIW, we currently have 3 servers that fit within Zlatko's #4 category.
Between all the servers there is about 4+ million files and about 1TB of
data on an HP disk array.  Journaling  is on and works great.  We average
about 1-5% changed files each night and backups typically take about 15-45
minutes for all 3 servers!

And I believe Zlatko is correct on his categorizing.  Windows "sees" disk of
type #1,2,3,4&5 as local.  (#5 is a bit of a special case however...)  It
cannot tell the difference between a DASD SCSI/RAID disk, and a SAN-attached
FC array.  Windows "speaks" SCSI to the SAN disks the same as it does to
DASD's and the HBA simply handles the FC encapsulation and transport (since
FC really just does exactly that: encapsulates the SCSI commands).  OS
has/needs no knowledge of it.  I would call up support again, as it SHOULD
work.

My two bits...

the GUI window >(one clear indicator).  Do his SAN drives appear under the
"Local" branch or "Network"?  >(I noticed at my old 4.2 level, my
locally-defined shares were listed under "Network" --- >\\server\uploads was
there, it even had the local path in parenthesis, on the c$ drive.)

Using Terminal services on the system I see the disk in question listed with
the rest of the disks under "Local" in the GUI; however I also see it under
Network. When I expand the tree I can see everything in both. The drive
letter also matches. Disk management shows it as a Dynamic disk.

This is at the latest client level in case I forget to say that.
