Additional Notes

OS upgrade from supporting out of kernel driver to OS version supporting in kernel driver

When RHEL or SLES is upgraded from supporting the OS version that supports the out of kernel driver to the OS version that supports the in kernel driver, old entries in the configure file will not be delete. For Qlogic in kernel driver, the following features are disabled:

Persistent binding

QLogic failover

QLogic driver parameter ConfigRequired and ql2xfailover do not need to be set.

For example:

For RHEL, vi /etc/modprobe.conf.

For SLES, vi/etc/modprobe.conf.local.

Delete the following unnecessary driver parameter:

options qla2xxx ql2xfailover=0 ConfigRequired=0

remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbin/modprobe -r --ignore-remove qla2xxx_conf; }

Then rebuild RAM disk.

Rebooting the host

Rebooting the host allows for reliable detection of newly added devices. The host may be rebooted after all I/O has stopped.

Unloading and reloading the modular QLogic driver

Stop all I/O.

Unmount all file systems attached to the QLogic driver.

If the Naviagent/CLI is installed and enabled on the host, then the Naviagent/CLI service must be stopped.

To stop the Naviagent/CLI service, issue one of the two following commands:

/etc/init.d/naviagentcli stop or

service naviagentcli stop
