## NAME
       iscsi_discovery - discover iSCSI targets

## SYNOPSIS
       **iscsi**___**discovery** _<IP>_ [**-p** _<port>_] [**-d**] [ **-t** _<tcp|iser>_ [**-f**] ] [**-m**] [**-l**]


## DESCRIPTION
       Perform  send-targets  discovery to the specified IP. If a discovery record is generated, try
       to login to the portal using the preferred transport (-t flag specifies the requested  trans‐
       port type, TCP is the default).  If login using a certain transport succeeds, mark the portal
       for automatic login (unless -m flag is used), and disconnect (unless -l flag is used).

       For iSCSI discovery to work, open-iscsi services must be running. i.e. iscsid should  be  up,
       and the iSCSI modules loaded. This is best accomplished by the init.d startup script.


       **[-p=]**_port-number_
              set the port number (default is 3260).

       **[-d]**   print debugging information.

       **[-t=]**_transport-type_
              set transport (default is tcp).

       **[-f]**   force  specific transport - disable the fallback to tcp (default is fallback enabled).
              force the transport specified by the argument of the -t flag.


       **[-m]**   manual startup - will set manual startup (default is automatic startup).

       **[-l]**   login - login to the new discovered nodes (default is false).
