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

1>][;lun=<lun

_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
