When using the Qlogic failover-driver we have to manually distribute active paths from the HBA driver-side (using SanSurfer - a Qlogic-utility for managing driver behavior) matching active path on our disk systems (DS4800 (IBM) and ST6580 (SUN)). This gives us some headache when thinking about administrating a lot of lun's from different disk enclosures.
The RDAC-driver do this automatically each time it's loading (it is embedded in the ramdisk image linux uses when booting), and we just need to manage active paths from the disk enclosure-side.
It might be an ASL issue, as the devices are UNCLAIMED when using the RDAC driver and CLAIMED otherwise.
