To ensure compatibility between Oracle FS Path Manager (FSPM) and your Emulex HBAs or converged network adapters (CNAs), be sure to follow the instructions in this section for installing the supported Emulex adapters and drivers.
- Install Emulex HBAs and CNAs according to the instructions at the Emulex support download page (currently http://www.emulex.com/downloads).
- Install the Emulex HBA and CNA drivers that come with the Linux distribution.
- Edit the /etc/modprobe.conf file to set the options for the lpfc driver.
If an options line already exists for this driver, modify it to include the recommended settings. If an options line does not exist, add one in the following format:options lpfc lpfc_devloss_tmo=60 lpfc_lun_queue_depth=64
- Rebuild the kernel to ensure that any changes to the driver are picked up.
Use the following command:
# /sbin/new-kernel-pkg --mkinitrd --depmod --install `uname -r`
- Reboot the host.
Note: Emulex provides utilities that can be used to set the driver options without rebooting the host. Refer to the
Emulex website (http://www.emulex.com/downloads/emulex.html) for details. If you use the Emulex utilities, you should still follow the steps above to update the configuration file and build a new kernel so that the options are in effect after the next reboot.
