The second command ("-m discovery") works. "-m discoverydb" doesn't
OK, that raises another question: what's the difference between
"discovery" mode and "discoverydb" mode? I'd been under the impression
that "discoverydb" was a synonym for "discovery" (or vice versa).
Apparently not.
The iscsiadm manpage is less than clear on this distinction:
-m, --mode op
specify the mode. op must be one of discoverydb, node, fw, host
iface or session.
If no other options are specified: for discoverydb and node, all
of their respective records are displayed; for session, all
active sessions and connections are displayed; for fw, all boot
firmware values are displayed; for host, all iSCSI hosts are
displayed; and for iface, all ifaces setup in /etc/iscsi/ifaces
are displayed.
... unless it's been updated since. Working from
iscsi-initiator-utils-6.2.0.871-0.20.el5_5
