NAME

iscsi-swp - Utility to get/set software write protect on an iSCSI LUN

SYNOPSIS

iscsi-swp [ OPTIONS ] <ISCSI-PORTAL>

iscsi-ls [-i --initiator-name=<IQN>] [-s --swp {on|off}] [-d --debug=<INTEGER>] [-? --help] [--usage]

DESCRIPTION

iscsi-swp is a utility to get or set the software write protect on an iSCSI LUN.

ISCSI PORTAL URL FORMAT

iSCSI portal format is 'iscsi://[<username>[%<password>]@]<host>[:<port>]'

Username and password are only required if the target requires CHAP authentication. Optionally you can specify the username and password via the environment variables LIBISCSI_CHAP_USERNAME and LIBISCSI_CHAP_PASSWORD.

Host can be specified either as a hostname, an IPv4 address or an IPv6 address. Examples:

	iscsi://192.0.2.1
	iscsi://[2001:DB8::1]:3261
	iscsi://ronnie%password@iscsi.example.com

Port is the TCP port on the target to connect to. Default is 3260.

OPTIONS

-i --initiator-name=<IQN>

This specifies the initiator-name that iscsi-ls will use when logging in to the target.

The default name is 'iqn.2007-10.com.github:sahlberg:libiscsi:iscsi-ls' but you can use this argument to override this. This is mainly needed for cases where the target is configured with access-control to only allow discovery logins from known initiator-names.

-s --swp {on|off}

By default iscsi-swp will only print the current setting of the software write protect bit. By using this argument iscsi-swp will also try to set/clear the flag on the target LUN.
