Driver for Linux -Troubleshooting Section Page 94

"attached usage count = -1" Error

Message. Some distributions of SuSE Linux

Enterprise Server 8 do not handle Peripheral

Qualifier Bits set to "1" in the Inquiry

response correctly. This can cause the

"attached usage count = -1" error message

to appear in the console while unloading the

lpfc driver followed by a panic.

There are two possible causes:

• A LUN scan utility issues INQUIRY

commands to non existent LUNS.

• A storage array (i.e., NEC, Fujitsu,

Clariion storage arrays) returns offline

LUNs in the report LUN response data.

This causes the SCSI midlayer to an issue

an INQUIRY command to an offline LUN

resulting in the error.

• If you need to run a LUN scan script on a Linux distribution

that does not support the peripheral qualifier bit set to 1, you

must set the lpfc_inq_pqb_filter configuration parameter to 1.

• If you need to attach Linux distributions with this issue to an

NEC istorage array, you must set the lpfc_lun_skip parmeter

to 1.

These parameters are contained in the lpfc.conf file. Refer to

the "View the lpfc.conf Configuration File" topic in the

Configuration manual to learn how to change these parameters.

"No Such Device" Error Message. You are

attempting to load the lpfc driver, but have no

HBAs installed. The "no such device" error

will be attached to the /directory path/lpfc.o

file. You will also see the error "Error loading

LPFC Driver".

Install an Emulex HBA and reload the driver. If the system

supports "Hot Swap", ensure that there is power to the HBA by

viewing its LEDs.

Operating Error Occurs When Attempting

to Run HBAnyware. When you attempt to

run HBAnyware, an operating system error

may occur. The computer may freeze.

Reboot the system.

Cannot See Any HBAs. You launch

HBAnyware and no HBAs are visible.

Try the following solutions:

• Perform an 'lsmod' to see if the Emulex drivers (lpfc and

lpfcdfc) are loaded. Look for an error message on the

command line stating the lpfcdfc driver is not loaded. If this is

the case, do an insmod of the lpfc and lpfcdfc drivers and re-

launch HBAnyware.

• Exit HBAnyware and run ../stop_hbanyware. Then run ./

start_rmserver and ./start_elxdiscovery, and re-launch

HBAnyware. The HBAs should be visible. If they are not

visible reboot your system.
