3.5.1 Matrix Server Installation Guide (June 2008)

Chapter 2: Install Matrix Server and MxFS-Linux 16

included with Matrix Server or a version from another source), you can

install that driver version in place of the Matrix Server default version.

For more information, see the section “Host Bus Adapters (HBAs)” in

Chapter 18 of the Matrix Server Administration Guide. Do not start Matrix

Server after installing the driver.

If you need to enable the failover feature provided with the QLogic HBA

driver, see Chapter 5 in the Matrix Server Administration Guide.

11. Reboot and Verify the HBA Configuration

Reboot the server. After the reboot, check for HBA drivers in the

configuration. Note the following:

• If you removed the HBA modules from the appropriate operating

system file (as described in Appendix A), no HBA drivers should be

loaded after the server is rebooted. (When Matrix Server is started, it

will load the HBA driver.)

• If you will be using third-party MPIO or will be booting from the

SAN, the kernel should have loaded the HBA driver.

Use the following commands to verify your configuration.

1. Run the command corresponding to your HBA type to determine

whether an HBA driver was loaded when the kernel rebooted:

# lsmod | grep lpfc

# lsmod | grep qla

2. If lsmod reports that an HBA driver was loaded, use one of the

following commands to check the driver version. The version will

appear in the first few lines.

Emulex:

# cat /sys/class/scsi_host/host<adapter>/lpfc_drvr_version

QLogic:

# cat /proc/scsi/qla2xxx/<adapter> | more
