IETADM

NAME

ietadm − iSCSI Enterprise Target Administration Utility.

SYNOPSIS

ietadm −−op [operation] −−tid=[id] [−−sid [id]] [−−params [key=value,...]]

DESCRIPTION

ietadm is used to monitor and modify in real-time the iSCSI Enterprise Target targets and volumes.

USAGE

You’ll have to get target ids from /proc/net/iet/volumes and sessions ids from /proc/net/iet/session. Some usage examples can be :

ietadm −−op show −−tid=1

display status of target 1 (see /proc/net/iet/volumes to get the matching target name)

ietadm −−op new −−tid=2

create dynamically a new target, numbered 2. CAUTION : the target will disappear if you restart ietd, you’ll have to edit /etc/ietd.conf to make it permanent!

ERROR MESSAGES

ietadm misses error messages. Look carefully the STDERR output : in case of error it will send a 3 number error code, ending with −1, for instance :

ietd_request 203 3 −1

OPTIONS

−−op new −−tid=[id] −−params Name=[name]

add a new target with [id]. [id] must not be zero.

−−op delete −−tid=[id]

delete specific target with [id]. The target must have no active sessions.

−−op show −−tid=[id]

show target parameters of target with [id].

−−op show −−tid=[id] −−sid=[sid]

show iSCSI parameters in effect for session [sid]. If [sid] is "0" (zero), the configured parameters will be displayed.

−−op new −−tid=[id] −−lun=[lun] −−params Path=[path]

add a new logical unit with [lun] to specific target with [id]. The logical unit is offered to the initiators. [path] must be block device files (including LVM and RAID devices) or regular files.

−−op delete −−tid=[id] −−lun=[lun]

delete specific logical unit with [lun] that the target with [id] has.

−−op delete −−tid=[id] −−sid=[sid] −−cid=[cid]

delete specific connection with [cid] in a session with [sid] that the target with [id] has. If the session has no connections after the operation, the session will be deleted automatically.

−−op delete

stop all activity.

−−op update −−tid=[id] −−params=key1=value1,key2=value2,...

change iSCSI IET target parameters of specific target with [id]. You can use parameters in ietd.conf as a key.

−−op new −−tid=[id] −−user −−params=[user]=[name],Password=[pass]

add a new account with [pass] for specific target. [user] could be [IncomingUser] or [OutgoingUser]. If you don’t specify a target (omit −−tid option), you add a new account for discovery sessions.

−−op delete −−tid=[id] −−user −−params=[user]=[name]

delete specific account having [name] of specific target. [user] could be [IncomingUser] or [OutgoingUser]. If you don’t specify a target (omit −−tid option), you delete the account for discovery sessions.

−−version

display version and exit

−−help

display a list of available options and exits

KNOWN ISSUES

	•		ietdadm doesn’t return any human-readable error message, only error codes.
	•		ietadm doesn’t modify or read the /etc/ietd.conf ietd configuration file.
	•		ietadm can’t use target names or aliases, only the tid found in /proc/net/iet/volumes.
	•		/proc/net/iet/session may list inactive sessions if the initiator doesn’t logout properly.
