# iscsi\_discovery(8)

discover iSCSI targets

## 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 transport 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).
