29 A TTO T echnology Inc. iPBridge Installation and Operation Manual not showing up, contact your service representative. 5 If all devices appear, invoke the ScsiTargets command several times on each SCSI port to verify that the devices can be seen. If devices disappear then ap pear again, the problem is most likely a SCSI cable.
30 2 If there are router s involved in the setup, make sure the IP addresses and/or MAC addre sses of the iPBridge are allowed through the route r. 3 Verify that the switch can see the iPBridge on the port(s) in question. Refer to your switch vendor’s guide for more in formation.
31 A TTO T echnology Inc. iPBridge Installation and Operation Manual Performance issues If the host is not getting th e performan ce it should, check the following items. Checking SCSI devi ces 1 Verify that the devices are r unning at their highest possible SCSI sp eed.
