Installing and Configuring the HBA and Driver
Configuring host files
Once the EMC storage array has devices assigned with device
addresses and the directors have been switched on line, the host can
see all the target storage array devices assigned to that host interface.
Devices are presented to the host in the same manner as devices
accessed through a standard SCSI interface.
To insure smooth integration and maximum performance from the
host and EMC storage array, you must edit these files:
◆ QLogic driver configuration file /kernel/drv/qla2x00.conf,
described under “Editing /kernel/drv/qla2x00.conf” on page 20.
◆ Host sd driver configuration file /kernel/drv/sd.conf,
described under “Editing /kernel/drv/sd.conf” on page 25.
◆ System specification file /etc/system, described under “Editing
/etc/system” on page 30.
You can modify the driver configuration files as described in the
sections referenced above, or by using the SANblade Control FX
utility, described under “Editing driver configuration parameters
using the SANblade Control FX utility” on page 27.
QLogic persistent binding implementation
QLogic persistent binding can be implemented through either the
SANblade Control FX utility or the QLogic driver configuration files
/kernel/drv/qla2x00.conf and /kernel/drv/sd.conf.
◆ To implement persistent binding through the SANblade Control
FX utility, proceed to “Editing driver configuration parameters
using the SANblade Control FX utility” on page 27. (Refer to step
8 on page 28.)
◆ To implement persistent binding through configuration files
/kernel/drv/qla2x00.conf and /kernel/drv/sd.conf,
continue with this section.
The matching between the driver instance number, target ID, and
storage array port name happens inside
qla2x00.conf. Each
mapping is considered a single property.
