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-8 lists 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
state
Provides the connection state of the specified adapter. Possible values
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-
tion
Provides the WWN of the given adapter.
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.
