Host Z (not shown) can be added to this configuration. SANsurfer FC HBA
Manager supports up to 30 hosts. The only limiting factor is that the
SANsurfer FC HBA Manager Agent must be run on each host in turn.
The RAID system offers eight LUNs, numbered 0–7. The RAID system
typically has its left and right controllers operating in an active/active
manner, with half the LUNs available on each controller.
Both hosts X and Y can recognize both targets on both adapters. In
SANsurfer FC HBA Manager, each target device is configured with one
adapter as its preferred path and (optionally) one adapter as its alternate
path. Ensure that both controllers are configured as enabled and not
masked on a target level.
On host X, the LUN mask for both controllers is set to enable LUNs 0–3 and
disable all other LUNs. This LUN mask must be consistent for both the left
and right controllers so that LUN alternates in the RAID system function
correctly. On host Y, the LUN mask for both controllers is set to enable
LUNs 4–7 and disable all other LUNs.
The two alternate systems function independently, based on the
configuration, operation of the RAID subsystem’s LUN alternate, and type of
failure that occurs. If access to a target controller is lost, RAID subsystem
LUN failover handles the recovery. If access to a target controller is available
on an alternate path, adapter failover handles the recovery.
