Enabling path failover for the sg interface
Through a collaboration effort that is named join driver, control path failover is supported through the sg interface, by using the latest lin_tape driver version on RHEL over Intel only.
Note: It is important to review hardware and software requirements before path failover is enabled. See Path failover and load balancing.
To enable it, the lin_tape_as_sfmp parameter must be set at /etc/modprobe.d/lin_tape.conf as follows:
options lin_tape alternate_pathing=1 options lin_tape lin_tape_as_sfmp=1
If lin_tape is already installed, follow the Uninstallation procedure.
Follow the Installation procedure by using
-with sfmp at rpmbuild.
