This accepts the syntax '-m session -r <n> -o new' and creates a new
session based on the session selected via the '-r' option, by setting
the 'multiple' flag in the session_rec_t.
Example:
# iscsiadm -m session
tcp: [4] <portal> <target>
# iscsiadm -m session -r 4 -o new
Logging in to [iface: iface0, target: <target>, portal: <portal>] (multiple)
Login to [iface: iface0, target: <target>, portal: <portal>] successful.
# iscsiadm -m session
tcp: [4] <portal> <target>
tcp: [5] <portal> <target>

In discovery mode, if the \fIrecid\fR and new operation is passed in, but the
\fI--discover\fR argument is not, then iscsiadm will only create a discovery
record (it will not perform discovery). If the \fI--discover\fR argument is
passed in with the portal and discovery type, then iscsiadm will create the
discovery record if needed, and it will create records for portals returned by
the target that do not yet have a node DB record.
