TCR still not installed, but I will install it this week

This was not the problem, because I've done it with the adapter cnfgdiag.exe
My original question :
=======================
Hello DU-Managers,
we want to setup a TruCluster Available Server Environment with two
servers.
server #1 : AlphaServer 2000 4/200,Firmware 5.2 (latest),DU V4.0B with
patchkit #8, KSPSA-BB Adapter (Firmware A11) SCSI-ID 6
server #2 : AlphaServer 800 5/333, Firmware 5.2 (latest), DU V4.0B with
patchkit #8, KZPSA-BB (Firmware A11) SCSI-ID 7
The resistor-packs on both KZPSA are removed. The servers are connected
to a Storage-Works Shelf BA356 via DWZZB-AA signal converter (terminator
resistor packs removed on differential-side) and Y-cables. The SCSI-Bus
is terminated on both sides with appropriate terminators.
We have following problems :
1.) After powering up the systems, sometimes the following
messages apears on the screen
waiting for pkc.0.6.0.8.0 to poll
CAM command EXECUTE_SCSI_INFO timed out
SIMPORT set device state command timed out
Maybe this problem is solved, because after replacing a SCSI-cable
this message dissapears and both servers can see the disk in the
storagebox. Has everybody seen this before ?
2.) SCSI-Bus-Reset OK ?
Although the KZPSA-Adapters are configured via cnfgdiag.exe to not
performing a SCSI-Bus reset, both servers performing a reset on the
shared bus, when booted. Will this be a problem for a running ASE ?
(Note : TruCluster - Software is not yet installed; see Question 3)
3.) Differences between TCR1.4 and TCR1.4a
In the moment I don't have access to TCR1.4a (Associated Product
CD #2 for V4.0B contains only TCR1.4; newer CD from DEC-Campus seems
to be lost, but PAK CD available; (when it was released ?)). Searching
for problems with
TCR1.4 in this mailing list shows only a problem with rpc.rquotad.
This problem is fixed in PatchKit #8 (Patch-ID OSF410-400214).
It is possible to use TCR1.4 with patch #8, or will I have a lot
of other problems. I want to install it now and perform an upgrade
to TCR1.4a as soon I have access to the CD's
TIA
