PCI-to-Fibre Channel Host Bus Adapter for IBM AIX - Installation Guide

Chapter 3
Maintenance and Troubleshooting
This chapter gives some common solutions to problems that can occur when installing a
Compaq StorageWorks PCI-to-Fibre Channel Host Bus Adapter (HBA) for IBM AIX.
The troubleshooting techniques described in this chapter do not identify all possible
problems with you HBA, nor do the actions suggested remedy all problems.
Troubleshooting
Use the errpt command to identify the cause of failure. The lsdev command will provide
the location of the component. For example, if errpt identifies a loose cable on the device
cdal, lsdev will give an address similar to:
cdal Available 00-02-01-3,0 Cambex SCSI...
Which indicates that the adapter is in location 00-02, and the drive is at SCSI ID 3, LUN 0.
