Logging on from the iSCSI Initiator Computer
For an iSCSI initiator node to access the volumes in a target node, it must log in to that target
node. After you create a volume, an iSCSI initiator, a network portal, and iSCSI target nodes, you
can log on to the xStack Storage Array from the iSCSI initiator computer. For example, using the
DSN-3200:
1.
Use an Ethernet RJ-45 cable to connect the appropriate xStack Storage Array Ethernet port
to the NIC in the iSCSI initiator computer or to your Ethernet switch.
2.
Configure the iSCSI initiator for use with the xStack Storage Array. This step varies according
to the operating system used with the iSCSI initiator. For more information, please refer to
the instructions for your iSCSI initiator software.
3.
Use the initiator software to Log In to the xStack Storage Array. The software should confirm
the log in with a response such as “Connected” and the initiator computer should be able to
see the volumes on the xStack Storage Array.
The log in process is begun by the initiator when it sends a log in request packet which includes
the world-wide unique name of the target node. The xStack Storage Array will accept the log in if
all of the following conditions are met:
The initiator’s name is in the list of allowed initiators for that target node.
The initiator connected to the xStack Storage Array using an xStack Storage Array IP address
and port number in the list of allowed network portals for that target node.
The CHAP secret (if CHAP is enabled) for the target node matches the one given by the
initiator. In addition, if CHAP is enabled and the initiator was given a password (on the
xStack Storage Array), the xStack Storage Array uses the CHAP protocol to validate that
password with the initiator.
In addition, a set of configuration parameters are negotiated between the initiator and target
during log in. A description of all the configuration parameters is beyond the scope of this
document. For more information, refer to the iSCSI IETF specification.
5.4.7
Changing the iSCSI Port Number
The iSCSI port number is the TCP/IP port number on which the iSCSI target is listening. The
standard port number for iSCSI is 3260, but some targets may allow the port number to be
customized. The following procedure describes how to change the iSCSI port number.
Changing this parameter is not recommended.
1.
Click the
xStack Storage
icon on the
Physical Resources
tab.
2.
Perform one of the following steps:
–
On the
File
menu, click
Change iSCSI Port Number
.
–
Right-click and click
Change iSCSI Port Number
