Warning in /var/log/vmkwarning file on ESX Server:

[nics30]

I have ESX3.5 U2 set up with SAN, I am getting a warning message in the /var/log/vmkwarning file which says the following:

vmkernel WARNING: Scsi id: 550: supports ANSI version 'SCSI-2' (0x2). In order be used with ESX a device must support the SCSI 3 protocol.

Is this something I should be concerned with and action?
