If you are not using an access list to restrict access, did you choose End Devices > iSCSI, select the Targets tab and check the Initiator Access All check box in Fabric Manager or use the all-initiator-permit CLI option to insure all initiators have access? • If restricting access to a particular interface(s), did you specify the correct Gigabit Ethernet interface(s)? Useful Show Commands to Debug Static iSCSI Configuration The show commands in this section are used to debug static iSCSI configuration. The following command output indicates correctly established iSCSI sessions. Run these commands on your switch and compare the output with these samples to help identify possible issues.
