Iscsi enterprise target administration utility.
ietadm --op [operation] --tid=[id] [--sid [id]] [--params [key=value,...]]
ietadm is used to monitor and modify in real-time the iSCSI Enterprise Target targets and volumes.
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. \s-1CAUTION\s0 : the target will disappear if you restart ietd, you'll have to edit /etc/ietd.conf to make it permanent!
ietadm misses error messages. Look carefully at the \s-1STDERR\s0 output : in case of error it will send a 3 number error code, ending with -1, for instance :
ietd_request 203 3 -1
--op new --tid=[id] --params Name=[name]
add a new target with [id]. If [id] is zero, the lowest free [id] is allocated automatically to the new target.
--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 \*(L"0\*(R" (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 \s-1LVM\s0 and \s-1RAID\s0 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 \s-1IET\s0 target parameters of specific target with [id]. You can use parameters in ietd.conf as a key.
--op update --tid=[id] --redirect=[destination]
set a temporary target redirection for target [id]. [destination] MUST be in the form <ip address>:port where :port is optional and if not specified port 3260 is assumed. IPv6 addresses must be surrounded by square brackets, e.g. [<ipv6 address>]:port. If the destination is empty then any existing redirection is cleared.
--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 show --tid=[id] --user
show a list of CHAP accounts. If --tid is omitted or [id] is \*(L"0\*(R" (zero), discovery accounts are displayed.
--op show --tid=[id] --user --params=[user]=[name]
show CHAP account information for the account specified by [name]. [user] can be [IncomingUser] or [OutgoingUser]. If --tid is omitted or [id] is \*(L"0\*(R" (zero), [name] is supposed to be a discovery account name.
--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
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.
