Installing and Configuring the QLogic HBA and v8.x-Series Driver

Description of QLogic v8.x-series driver parameters

When attaching to CLARiiON and Symmetrix Storage Arrays, EMC

recommends that the

ConfigRequired and ql2xfailover

parameters be set to zero.

General driver

parameters

◆ ql2xopts: string that defines additional driver options and

persistent binding info.

◆ extended_error_logging: defines whether to enable extended

error logging.

◆ ql2xioctltimeout: defines the IOCTL timeout value in seconds

for pass-through commands.

◆ ql2xprocessrscn: defines whether to enable port RSCN

handling via a series of less intrusive fabric ADISC and PLOGIs.

◆ ql2xprocessnotready: defines whether the driver handles

NOT_READY's.

◆ ql2xloginretrycount: defines an alternate value for the

NVRAM login retry count.

◆ ql2xdoinitscan: defines whether the driver should send a

signal to the SCSI mid-layer to perform a scan of the SCSI bus

after the QLogic driver has loaded.

◆ ql2xsuspendcount: defines the number of 6-second suspend

iterations to perform while a target returns a NOT_READY

status.

◆ Bind: defines the method for target persistent binding method. If

set to 0, then the Portname will be used; if set to 1, the PortID will

be used.

◆ ConfigRequired: If set to 1, then only devices configured and

passed through the ql2xopts parameter will be presented to the

OS.
