HI Jiang,
Are you using the driver from the SANLink3 F2 downloads page? This is known to not work correctly with Sequoia.
With a beta driver I have connected a SANLink3 F2 to an E5800f and can see the LUNs presented, create an HFS+ filesystem on them and can copy files.
If the SFP link light keep flashing then the FC is not connecting. Normally this means that there is some issue with the fibe cables or the SFPs on both sides have no compatible speeds. If you are using the driver from the downloads page on Sequoia, it's probably the driver.
A simple component test is to connect both SFPs to the SANLink and connect the FC cable between then, the link lights of both FC ports should be solid green.
This tests the driver, both SFPs and the cable.
For information about the beta driver, please email the support alias at support@promise.com.
