iSCSi node SettingS
From the Storage tab, click iSCSI Target > iSCSI > Node > Settings to
display the iSCSI Node Settings menu used for iSCSI target configuration.
The configuration settings are described in the table below.
Menu Description
Node Name
This is the target name used by an initiator when
logging on for iSCSI connection. A unique Node Name
is generated automatically, however it can be changed
here.
Node Alias
Name used for easy identification of the DataGuard
Appliance on the network.
MaxBurst-
Length
This is the maximum data payload in a sequence of
Data-In or solicited Data-Out PDUs, in bytes, kilobytes
or megabytes. A data sequence consists of one or
more consecutive sequence of Data-In or Data-Out
PDUs terminated with a Data-In or Data-Out PDU with
the F bit set to one (finish flag). A Data-Out sequence
is sent either unsolicited or in response to an request
to transmit (R2T). This value is set when the initiator
session is negotiated at login.
TimeToWait
The default time to wait is the minimum time, in seconds,
to wait before attempting an explicit or implicit logout,
or active iSCSI task reassignment after an unexpected
connection termination or connection reset. The default
is 2 seconds. If this is set to 0, an attempt to reconnect
will happen immediately.
DefTimeTo
Retain
This is the maximum time, in seconds after an initial wait
(TimeToWait), before an active iSCSI task reassignment
is possible after an unexpected connection termination
or reset. The default is 20.
Enable Header
Digest
When enabled, this increases data integrity by
performing a checksum of each iSCSI Protocol PDU’s
header. Enabling this can affect iSCSI performance.
Enable Data
Digest
When enabled, this increases data integrity by
performing a checksum of each iSCSI Protocol PDU’s
data part. Enabling this can affect iSCSI performance.
Enable
Uni-directional
CHAP
Authentication
This must first be enabled to use uni-directional CHAP
for initiator authentication.
Enable
Bi-directional
CHAP
Authentication
This must first be enabled to use bi-directional CHAP for
mutual initiator/target authentication.
NOP-IN
Allows the initiator to issue a request for response from
the target without requesting any other actions. This is
used to ensure the connection is still alive or that the
target is responsive.
Menu Description
Port ID
The Port Identifier is a Fibre Channel address identifier
assigned to a node port or node loop port during fabric
login.
iSNS Enable
Check to toggle on iSNS protocol support.
Server IP
Address
The iSNS server responds to iSNS protocol queries and
requests made by iSNS clients. Enter the IP address of a
functioning iSNS server in the Server IP Address field.
iSNS Port
[1~65535]
Choose the TCP port used for iSNS communications. The
default iSNS protocol port is 3205.
iSCSi port view
To display the read-only iSCSI Port settings, go to Storage > iSCSI
Target > Port.
iSnS port SettingS
The Internet Storage Name Service protocol is used for automatic
discovery of iSCSI devices as well as state change notification. iSNS
servers can also store mappings of Fibre Channel devices to proxy
iSCSI device images on the network. Use the iSNS Port Settings menu
to enable iSNS and configure iSNS server IP and port settings.
Various iSCSI information can be viewed by clicking on the menus tabs
and expanding the View menu. Some tabbed menus include Settings
configuration menus.
iSCSI Session
From the Storage tab, click iSCSI Target > Session tab to display any
active iSCSI sessions.
