Unable to "see" a Sun StorEdge 3510 FC Disk Array disks from 2 hosts simultaneously

        Hi managers,

        I have a Sun StorEdge 3510 FC Disk Array (3510) with 2 RAID controllers.

        The 3510 has default SFP configuration -- only 4 slots have SFPs in them.
        The 3510 was connected to only one Sun host and the host was "seeing" and working with all 3510's disks without any problem.

        Since I need the 3510 to be used by more than one Sun host, i connected another host to it.
        The first host is connected to FC0's SFP and the second one is connected to FC1's SFP. They are on different 3510's RAID controllers in the default SFP configuration.
        The first host continue working without problems with 3510's disks.
        The second host shows the attachment to the 3510 with the appropriate kernel messages, but it can't "see" any one of the 3510 disks.

        On the 3510 there is no WWN filtering set!

        Could someone help me with this issue ?

        Thanks in advance!

                Vladimir
