Configuring host files

Installing and Configuring the HBA and Driver

◆ If the system was booted from the SAN using a QLogic adapter,

ensure that no change is made to the persistent binding of the

boot device (that is, Target and LUN). Failure to do so will result

in a hung system, or a panic, as the system will no longer be able

to find its root partition.

Dynamically configuring Targets/LUNs

1. To modifying the

/kernel/drv/qla2x00.conf file:

•If FC-SW:

– Make persistent binding entry for each target device as

described under: “QLogic persistent binding

implementation” on page 19.

– Set parameter

hba0-connection-options=1;

– Set parameter

hba0-persistent-binding-configuration=1;

•If FC-AL:

– Set parameter

hba0-connection-options=0;

– Set parameter

hba0-persistent-binding-configuration=0;

2. Run the qlreconfig utility:

cd /opt/QLogic_Corporation/drvutil/qla2x00

./qlreconfig -d qla2x00

CAUTION

After the qlreconfig utility is run, the host still adds new devices

in the background. Thus, the more new devices added to the host,

the longer the time it takes to complete buildup.

Dynamically configuring driver parameters

1. Enter the desired values of parameters in the

/kernel/drv/qla2x00.conf file.

2. Run the

qlreconfig utility:

cd /opt/QLogic_Corporation/drvutil/qla2x00

./qlreconfig -d qla2x00
