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 is the number that you calculated. (Your file may contain additional module parameters.) For a QLogic HBA, add "ql2xmaxqdepth=" after the fourth field (scsi). 0x1077 0x2300 qla2300 scsi "ql2maxqdepth=" QLogic 2300 Adapter w/v6.01 driver For an Emulex HBA, add "lpfc_lun_queue_depth=" after the fourth field (scsi). 0x10df 0xf900 lpfcdd scsi "lpfc_lun_queue_depth=" 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.
