3.7.0 HP StorageWorks HP Scalable NAS File Serving Software administration guide - HP Scalable NAS 3.7 for Linux (AG513-96002, October 2009)

Change the HBA queue depth
To change the HBA queue depth, you will need to edit the /etc/opt/hpcfs/
fc_pcitable file. In the file, locate the line for your HBA driver. The following
examples are for QLogic 2300 and Emulex 9000 drivers.
#0x1077 0x2300 qla2300 scsi QLogic 2300 Adapter w/v6.01 driver
#0x10df 0xf900 lpfcdd scsi Emulex Lightpulse 9000 Fibre Channel Adapter
Edit the line as follows:
• Remove the comment character (#) from the beginning of the line.
• Add a module parameter containing the queue depth that you calculated earlier.
Following are some examples, where <value> is the number that you calculated.
(Your file may contain additional module parameters.)
For a QLogic HBA, add “ql2xmaxqdepth=<value>” after the fourth field (scsi).
0x1077 0x2300 qla2300 scsi "ql2maxqdepth=<value>" QLogic 2300
Adapter w/v6.01 driver
For an Emulex HBA, add “lpfc_lun_queue_depth=<value>” after the fourth
field (scsi).
0x10df 0xf900 lpfcdd scsi "lpfc_lun_queue_depth=<value>"
Emulex Lightpulse 9000 Fibre Channel Adapter
After editing the file, you will need to stop HP Scalable NAS, unload the HBA driver,
and then restart HP Scalable NAS:
# /etc/init.d/pmxs stop
# /etc/init.d/pmxs unload
# /etc/init.d/pmxs start
Replace an HBA card
To replace an HBA card, complete the following steps:
1. Shut down the HP Scalable NAS software:
# /etc/init.d/pmxs stop
2. Disable the HP Scalable NAS startup script. Type this command:
# /sbin/chkconfig --del pmxs
