Symmetrix Fibre Channel with Qlogic HBAs on Linux Hosts

Arbitrated Loop Configurations

Discussion of Default

and EMC-Approved

Drivers

EMC supports only the QLogic qla2x00(smp) driver, which can be

downloaded from the QLogic Website.

EMC does not support the qlogicfc driver that is included in the Linux

kernel (because the driver does not support persistent binding). Also,

EMC does not support the alternate qla2x00 driver that is included in

the kernel in the Red Hat v7.0 distribution.

If the QLA2200F HBA is present in the system prior to a new

installation of Linux, the Red Hat installation application

automatically loads its version of the driver, which will be installed

and inserted automatically when the host reboots. For this reason,

EMC highly recommends installing the Linux operating system before

installing the QLogic HBAs.

Removing the Default Driver

If the Qlogic QLA2200F is installed in the system prior to the Linux

installation, the default driver must be removed from the kernel after

rebooting, as follows:

1. Issue the appropriate command:

2. Edit the modules file to remove the unsupported driver:

a. Issue the appropriate command:

b. Remove the appropriate entry:

Linux Version Enter:

6.2 modprobe -r qlogicfc

7.0 modprobe -r qla2x00

Linux Version Enter:

6.2 vi /etc/conf.modules

7.0 vi /etc/modules.conf

Linux Version Remove:

6.2 alias scsi_hostadapter qlogicfc

7.0 alias scsi_hostadapter qla2x00
