1st time poster looking for help.
Systems:
2 - Alpha 4100 in an available cluster running 4.0D
SCSI Info:
4 SCSI channels. Systems are 'Y' cable connected
Path is EMC Symmetrix 3430 (4 SCSI channels) --> SystemA 'Y' cable -->
SystemB 'Y' cable --> Terminator
We are attempting to add 2 devices per channel (4.5GB virtual slices) .
There are currently 5 devices per channel ( 9GB virtual slices). ( Plus
gatekeepers)
The 2 devices per channel that we are trying to add were previously
configured on a different EMC channel to a different 4100 that has been
phased out and off of EMC.
The 2 devices per channel are simply being reassigned to different channels.
The desired result is to see 7 devices per SCSI channel ( plus gatekeeper).
PROBLEM:
After the EMC config has been done to add the 2 new devices per channel the
following is happening. ( All at the system/delta
level prior to OS).
When I poll SystemB ( p000>>sh dev pks*) I see the appropriate devices per
SCSI channel ( 7 devices plus gatekeeper, 0.0,1.0,2.0,3.0,4.0,5.0,6.0 +
15.0)
When I poll SystemA ( p000>>sh dev pks*) I see too many devices per SCSI
channel ( 15 devices
0.0,1.0,2.0,3.0,4.0,5.0,7.0,8.0,9.0,10.0,11.0,12.0,13.0,14.0,15.0)
EMC is looking into the problem, however, I can only keep my system down so
long to troubleshoot.
It is very confusing to see 2 systems on the same SCSI path and physical
cable reporting different devices attached.
The only difference from the last time we added devices to the channels is
that prior the devices were new. This time the devices were reassigned and
in use before.
Any and all help would be greatly appreciated.
Thanks,
