Hi all,
Thanks to Pat Barrowclough & Mike, who have give following solution and confirmed the configuration. It really worked:
If you are using external SCSI terminators have you remembered to remove the
terminators from the host adapters. If you have try just using one ES40 and
a Y cable with two terminators, if that works extended that configuration
another cable till your problem recurs.
*************************************************************
I 'm recently working on installation of TruCluster on Rackmount 2*ES40 and
RA3000 box. Both ES40 has 3X-KZPBA-CC (PCI to USCSI Differential Host
Adapter) connected to Dual HSZ22 controller.
I did many combinations of connecting SCSI cables but except one all the
combinations give scrolling message:
"PKC0.3....polling for devices....."
and doesn't come to console SRM prompt. I have changed the SCSI ID for Host
adapter to 6 and the other Host adapter is default 7.
The Cable combination that worked is as follows:
a) Host-0-In to First ES40 Server using BN37-05(VHDCI to VHDCI)+
(BN38-0E)VHDCI to 68HD+(BN21K)Ycable+ (H879)68
pin Terminator.
b) Host-0-Out to Host-1-In connected with BN37-0E (VHDCI to VHDCI)
c) Host-1-Out to Second ES40 Server using BN37-05(VHDCI to VHDCI)+ VHDCI to
68HD+Ycable+ 68 pinTerminator.
Other best option that didn't work was:
a) To Connect on First ES40 Server, Y cable with Terminator & other end to
second ES40 Y cable -- second end Ycable to HSZ22 Host-0-In.
b) Host-0-Out to Host-1-In connected with BN37-0E (VHDCI to VHDCI)
Now please let me know if the First Cable combination I prepared is ok with
TRuCluster or is there any other combination I have to follow for Cluster &
Dual HSZ22 Controllers?
TIA.
Regards.
