How to set scsi-initiator-id for Peripheral Component Interconnect based machines which use the Gigabit Link Module device driver with the Symbios cards

Solution



For instance, where two Peripheral Component Interconnect (PCI) based machines use the Gigabit Link Module (GLM) device driver with the Symbios controller card, and both machines are connected to the storage on the same SCSI bus, the following tactic can be used to set the scsi-initiator-id on one machine and avoid SCSI ID conflicts:

Be sure to change the SCSI IDs for all controllers and paths to the shared disks, leaving the global scsi-initiator-id set to 7. This can be done by modifying the glm.conf text file in the /kernel/drv directory.

The syntax for the file is as follows :

# global settings can be overridden by instance
# specific settings ..
# they apply to all the instances of the driver

scsi-initiator-id=7

# instance-specific settings, override the global settings just
# for these instances

name="glm" parent="/pci@4,2000" unit-address="1" scsi-initiator-id=6;
#
name="glm" parent="/pci@4,2000" unit-address="1,1" scsi-initiator-id=6;
#
name="glm" parent="/pci@1f,2000" unit-address="1" scsi-initiator-id=6;
#
name="glm" parent="/pci@1f,2000" unit-address="1,1" scsi-initiator-id=6;
#


The system now should be able to boot up with the new scsi-initiator-id for both the controllers.
