Using MegaRAID Drivers on SGI InfiniteStorage Servers
To avoid I/O timeouts with certain workloads, the megaraid_sas driver needs to have the
poll_mode_io variable set to 1. For Novell operating systems, the file
/etc/modprobe.conf.local needs the following line added:
options megaraid_sas poll_mode_io=1
This modification will be made on systems shipped from the factory, but if a system is installed
or upgraded in the field, this change will have to be made after installation/upgrade.
