FIN

Any FC-AL PCI loop where A5X00 Storage Arrays are directly connected to i) a host using PCI FC100/P initiator card without hub, or ii) other host (dual host) with FC-AL initiator-card is connected to the same loop may experience the following errors as described in BugId 4243157.
Sample error messages:

UPDATE FOR FIN I0541-2:

The Corrective Action on FIN I0541-1 provides two different options or solutions to the above mentioned problems as follows:

• OPTION-1: The FC100/P card is the only Initiator on any one loop where Sun A5x00 Storage Array are direct connected.
• OPTION-2: A Sun FCAL hub is placed between the FC100/P card(s), and the A5X00 Storage Array. In this case, more than one host-adapter on the same loop, may be used.

Due to resistance from the Field over the cost of implementation, OPTION-2 has been removed from the Corrective Action. This option would have required the customer to purchase and connect a hub to the A5x00 Storage Array. The Corrective Action now recommends only OPTION-1 for avoiding this FC100/P card problem. This restriction is advantageous from high-availability/RAS point of view since having each host on a separate loop removes a single point Of failure (SPOF) in Multi Initiator configurations.
