Maintenance and Troubleshooting

Verifying SCSI bus configuration

Items to check include:

■Termination — Problems with termination can cause intermittent or hard failures. A SCSI bus must be terminated on both ends. Termination problems are common when both narrow and wide devices are on the same bus.

■Bus Type — On an LVD SCSI bus, SE and LVD devices can be connected to the same bus. However, if one SE device is detected during power on, communication to all devices converts to SE mode.

■Device ID — Each device on a SCSI bus must have a unique ID. Verify configured IDs are not in use by other devices on the same SCSI bus.

■Cabling — Check SCSI cables to verify they are functional. SCSI rules for total length, distance between devices, and stub length must be followed. Connections should also be checked and reseated if necessary.

■SCSI Devices — Verify that the SCSI devices on a particular SCSI bus can be seen in the Configuration Menu of the FC interface controller. If the FC interface controller cannot see the devices, verify SCSI configuration, cabling, and termination.

Verifying FC port connection

If SCSI devices are recognized on the SCSI buses, but do not appear to the FC host, it may be that the FC link is not properly established. Most hubs and switches have link indicators showing link status. When the FC interface controller is connected and powered on, this link indicator should be solid. If it is not, check the cabling or connections.

One method of verifying link integrity when connected to a functional host, involves disconnecting and then reconnecting the FC cable. This procedure should cause momentary activity of this indicator as the link reinitializes.

Additionally, verify that the cable type of the FC interface controller and the attached hub, HBA, or switch is of corresponding types. When using optical media, verify that the attached device is using non-OFC type optical devices.
