Table 33 iSCSI Advanced configuration and parameter definitions
Target iqn.<yyyy-mm>.<tld.domain.host.Target#>[:<identifier>]
Identifies the iSCSI Qualified Name, which is globally unique as required by the iSCSI standard.
iqn. followed by a single dot “.”
<yyyy-mm.> is the date (year and month) at which the domain is valid followed by a single dot “.”
<tld.domain.> Reversed domain name followed by a single dot “.”
<host.>Host name is assigned on Maintenance->Network page, followed by a dot “.”
<Target#> is set to numerically enumerate each iSCSI target definition. (e.g. Target0, Target1 etc)
The optional <identifier> - permitted by RFC3720, but is not used
IncomingUser <username> <password>
Used to set the <username> and <password> to authenticate iSCSI initiators during discovery sessions, using
CHAP.
Several entries can be specified for each target discovery. If no IncomingUser is specified, any initiator may open
a discovery session.
Note: RFC 3720 requires <password> to be 12 characters long. This is enforced by Microsoft’s® Initiator.
OutgoingUser <username> <password>
Used to set the <username> and <password> to authenticate the target to initiators during discovery sessions
using CHAP. Only one outgoing <username>/<password> combination may be specified.
Note: RFC 3720 requires <password> to be 12 characters long. This is enforced by Microsoft’s® Initiator.
Alias <string>
May be set to a “friendly” human-readable name or description that is communicated to the initiator at Login.
An initiator may elect to display this value when listing connected targets.
NOTE: As an additional feature, this string is appended to the target name.
MaxConnections <value>
Default 1
Sets the maximum number of connections an initiator may make with a each iSCSI target entity. 1 is the only
valid value
InitialR2T <Yes|No>
"No" — default: Indicates the initiator may include BurstLength bytes together immediately following an iSCSI
command. This setting may reduce protocol handshakes, and thus improve system performance.
"Yes" — Indicates the initiator has to wait for the target to solicit SCSI data before sending it.
ImmediateData <Yes|No>
"Yes" — default: Indicates the initiator may combine iSCSI command and data information and send in the same
packet. This setting may reduce protocol handshakes, and thus improve system performance.
"No" — Indicates the initiator may not combine command and data information in the same packet.
MaxRecvDataSegmentLength <value>
Default: 262144, sets the maximum data segment length that the target can receive.
Note: The <value> should be set to multiples of PAGE_SIZE. The maximum supported value is 64 * 4096 =
262144.
MaxXmitDataSegmentLength <value>
Default: 262144, sets the maximum data segment length that the target can send.
Note: The actual value is reduced to match the MaxXmitDataSegmentLength and the
MaxRecvDataSegmentLength negotiated with each initiator during login. The <value> should be set to multiples
of PAGE_SIZE.
The maximum supported value is 64 * 4096 = 262144.
#MaxBurstLength <value>
Default: 262144, Sets the maximum amount of data the initiator may send in a single burst.
