You may see an error like the following:
scsi: unknown type 12
  Vendor: Compaq    Model: CR3500            Rev: x2m

Basically for 2 SCSI adapters to properly access the one CR3500 storage box, you need to have the adapters use different HOST ID numbers. One should be at 7 and the other at 6.

This is done in the /etc/modules.conf file on each of the 2 CL1850R servers. The top CL1850R's /etc/modules.conf should look like the following:
alias scsi_hostadapter sym53c8xx
alias eth0 eepro100
alias eth1 eepro100
alias scsi_hostadapter1 cpqarray
alias parport_lowlevel parport_pc
options sym53c8xx sym53c8xx="hostid:7"
The bottom CL1850R's /etc/modules.conf should look like the following:
alias scsi_hostadapter sym53c8xx
alias eth0 eepro100
alias eth1 eepro100
alias scsi_hostadapter1 cpqarray
alias parport_lowlevel parport_pc
options sym53c8xx sym53c8xx="hostid:6"
