Environment:

NBU Enterprise 6.0 MP3
Master Server - Windows Server 2003 SP1
                        HBA Emulex LightPulse LP11002-E

Media Servers - Windows Server 2003 SP1
                        HBA Emulex LightPulse LP10000

Encryption -    NeoScale CrypoStor FC702. Firmware fc-2.3.2-Build3

Library -               ADIC (Quantum) i2000. Firmware 4.4.2
                        Drives - IBM FC LTO2 (IBM Ultrium-TD2). Driver
6.0.7.1                         Drive Firmware 5AT0

The issue:
After a firmware upgrade on the i2000 and the CryptoStor's to the levels
noted above, all jobs using the Master server as the Media server would
fail with Exit Status 84. All jobs submitted to the Media servers ran
without incident.

The only common denominator seems to be that the Master server has
Emulex LightPulse LP11002-E HBA's, and the Media servers run Emulex
LightPulse LP10000 HBA's.

The solution provided by NeoScale was to utilize the following touch
file on the Master:

< install_dir >\ Volmgr\ database\ NO_SIXTEEN_BYTE_CDB " touch file.

This fixed the problem, but to this day no one seems to really know why.
There is an active case open with all 3 hardware vendors.

The following Tech Note was offered as a partial explanation; but it
falls short of being directly applicable to our problem/environment (we
are running FC LTO2's, not AIT-4).

I can't help but think this environment is not all that unique. Is
anyone else running this configuration, and if so, do you have to use
the touch file?


Thank you,
