information. The Linux path failover driver and the HP-UX operating system have built-in load balancing
and when a tape drive is opened the operating system selects the best path based on the current path
loading.
The Linux advanced path failover driver has a command for requesting a partition path to be preferred.
That setting will only persist until the next reboot because the hardware configuration can change when
the server reboots. The driver is unable to detect whether the hardware is the same as the previous boot
so the preferred setting is not retained across reboots. You can use a boot time script to set the preferred
path at each boot when the hardware configuration is stable. For persistent path binding, use Linux udev
rules to create persistent paths.
After the host has been configured and booted, install the drivers necessary for the host operating
system.
