HP Surestore Tape Library Model 10/180 HP Surestore Bridge FC 2/1 LV and FC 4/ - Page 192

Cannot Confirm Connection Through a Fibre Channel Switch 1. Check the LED indicators on each switch port. - Steady green indicates that the port is online (connected with a device over FC). - Flickering green indicates frames are being transferred through the port. - Yellow indicates port is not online, is disabled, or in fault. 2. No light indicates no module, no cable, or power is off. 3. Telnet into the switch using instructions provided with the switch. 4. Using the SwitchShow command, confirm that the ports connected to the FC HBA and the bridge are online. 5. Using the nsShow command, confirm that the FC HBA and the bridge have logged into the name server. 6. Refer to the FC switch documentation for service procedures. Cannot Confirm the Library or MO Jukebox Connection (HP-UX) 1. Confirm the library or MO jukebox connection by using the ioscan command. 2. Before powering-on the bridge, make sure the library or MO jukebox and drives are configured for SCSI. This can be done through the library's front panel. 3. Make sure the library or MO jukebox, drives, bridge, and switch are powered-on and connected properly. 4. Verify SCSI bus configuration: Check all appropriate devices for the following conditions: - Termination: Problems with termination can cause intermittent or hard failure. Terminate the SCSI bus on both ends of the bus. By default, the bridge provides internal termination at the end of each SCSI bus. Check each terminator and connector for bent pins. - Bus Type: Single-ended devices cannot be combined with differential devices on the same bus. The FC 4/1 HV bridge provides only HVD SCSI buses. SE or LVD SCSI devices cannot be supported on this bridge. Verify that all devices hooked up to each bus of the FC 4/1 HV are HVD SCSI devices. 194 Diagnosing Problems Chapter 8
