Chapter VII. iSCSI PDU Offload Target
Chelsio T5/T4 Unified Wire For Linux Page 119
WWN=xxxxxx is a 16 character unique
value set for multipath aware iSCSI
initiator host.
When multipath aware initiator host is
accessing the storage Logical Unit
Number( LUN) via multiple iSCSI
session, ScsiID and WWN values must
be set for the TargetDevice. These
values will be returned in Inquiry
response (VPD 0x83).
Multiple TargetDevice key=value pairs
are needed to indicate multiple
devices.
There can be multiple devices for any
particular target. Each device will be
assigned a Logical Unit Number (LUN)
according to the order it is specified
(i.e., the first device specified is
assigned LUN 0, the second one LUN
1, …, and so on and so forth).
NOTE: FILE mode is the most versatile
mode, if in doubt use FILE mode.
*During MPIO i.e. when two iSCSI
targets are using the same
TargetDevice, intermittently it is
observed that LUN shows up twice on
the initiator, to work around this
behavior, try using the same
TargetAlias on both the targets.
ACL_Enable
“Yes”
“No”
“No”
No
Defines if Chelsio’sAccess Control List
(ACL) method will be enforced on the
target:
Yes: ACL is enforced on the target
No: ACL is not enforced on the target
ACL
[iname=<name1
>][;<sip=<sip
1>][;dip=<dip

_list:permiss
ions>]
Yes
The ACL specifies which initiators and
how they are allowed to access the
LUNs on the target.
iname=<Initiator Name> specifies
one or more initiator names, the name
must be a fully qualified iSCSI initiator
name.
sip=<Source IP address> specifies
one or more IP addresses the initiators
are connecting from.
Dip=<Destination IP address>
specifies one or more IP addresses
that the iSCSI target is listening on
(i.e., the target portal IP addresses).
NOTE: when configuring an ACL at
least one of the above three must be
provided:
 iname, and/or
