How to check that which storage connected either FC or iscsi

Question

How do i check that, which type of storage are connected with my linux(Redhat) system. I want to find that either ISCSI or FC storage connect ?

Do you have `iscsiadm`? `lscpi`? What linux distribution? What sort of storage system are you running? — jesse_b, Jan 31 '19 at 18:00

Run lsscsi -t. For FC devices, the 3rd column will say fc:<port name>,<port id>. For iSCSI devices, it should display the iSCSI target name (e.g. iqn.2001-04.com.example:sda.sdb.sdc), although this could vary depending on whether you're using a hardware or software implementation of iSCSI.

For example, this is a FibreChannel LUN:

[0:0:0:0]    disk    fc:0x500507680c258479,0x0b0801  /dev/sdb

And this would be an iSCSI LUN:

[2:0:0:0]    disk    iqn.2001-04.com.example:sda.sdb.sdc,t,0x1 /dev/sda

for FC try

systool -c fc_host -v

which give a report for all FC card, and a more details for connected one.

You are seen by SAN with the wwid given by port_name

if no FC present (*)

Error opening class fc_host

(*) note that not present and unconnected are different thing.
