Debugging Using Proc Information

Debugging Using Proc Information

The driver /proc/scsi/qla2xxx/<adapter_number> provides debugging information that can help you troubleshoot problems with the driver. The /proc entry provides firsthand information about the current state of the driver.

Table A-8lists the /proc output fields and provides a description of each.

	Table A-7. Proc Output
Output Field		Description
Boot Code Version	Provides the version of the boot code present on the adapter. A version
	of 0.00 indicates that the boot code is corrupted or not present, and
	must be updated to perform a boot from SAN (see “Configuring Boot
	from SAN” on page 3-12).
Number of ISP aborts	Provides the number of times the system chip has been reset. Typically,
	whenever the system NVRAM or Flash is updated, the chip is reset to
	use the updated information. Otherwise, the chip is reset only if an error
	occurs. This number thus provides a close approximation of whether the
	chip has been operating properly.
Host adapter FC link	Provides the connection state of the specified adapter. Possible values
state	include the following:
	READY:	Ready to perform I/Os.
	UPDATE: The topology is being re-discovered.
	DEAD:	No connection.
	DOWN:	Intermittent state, link temporarily down.
NPIV Supported	Indicates whether the given adapter node supports NPIV. If yes, the sub-
	section provides the maximum number of virtual ports supported.
SCSI Device Informa-	Provides the WWN of the given adapter.
tion
FC Port Information	Lists all Fibre Channel ports to which the specified adapter is connected.
	The last entry in this field indicates the login status of the port and
	whether the port is operating in target or initiator mode.
SCSI LUN Information	Lists all the LUNs visible to the specified adapter.
