Troubleshooting and monitoring
The /proc pseudo file system
The /proc pseudo file system is maintained by the Linux kernel and provides dynamic information about the system. The directory /proc/scsi contains information about the installed and attached SCSI devices.
The file /proc/scsi/scsi contains a list of all attached SCSI devices, including disk, tapes, processors, and so on. Example
Example: A-16 Sample /proc/scsi/scsi file
knox:~ # cat /proc/scsi/scsi |

There also is an entry in /proc for each HBA, with driver and firmware levels, error counters, and information about the attached devices. Example
Example: A-17 Sample /proc/scsi/qla2300/x
knox:~ # cat /proc/scsi/qla2300/2
QLogic PCI to Fibre Channel Host Adapter for ISP23xx: Firmware version: 3.01.18, Driver version 6.05.00b9
Entry address = c1e00060 HBA: QLA2312 , Serial# H28468
Request Queue = 0x21f8000, Response Queue = 0x21e0000
