2.2
Configure iSR6250 Management Port IP Address
To set the IP address of the management port for each blade:
1. Connect the router’s Management Port (10/100 Ethernet) to your workstation using a switch or hub. As
an alternative, you may connect your workstation directly to the router using an Ethernet crossover
cable. For a serial console, use the following settings:
‰ Bits per second: 115200
‰ Data bits: 8
‰ Parity: None
‰ Flow control: None
The iSR6250 management port’s default IP address is 10.0.0.1 subnet 255.0.0.0. Make sure
the workstation connected to the iSR6250 router has Ethernet address 10.0.0.x, where x is other
than 1 and subnet mask is 255.0.0.0.
2. From the workstation, open a command window and using a telnet session connect to iSR6250 using
IP address 10.0.0.1.
3. Login as guest and use the password password. This will take you to a Command Line Interface
(CLI) prompt.
4. Select the blade you want to configure by entering one of the following CLI commands:
blade r1 (for blade 1)
or
blade r2 (for blade 2)
SN0051420-00 A

Install SANsurfer Router Manager
5. Enter the following CLI commands (for blade 2) at the prompt iSR6250 (admin)#>:
admin start (default password is config)
set mgmt
6. Select the mode. QLogic recommends using a static address. Select Option 0 and enter the IP
address, subnet information, and gateway, if applicable.
You will lose the connectivity of the telnet session at this time. If you want to continue using the CLI,
restart the telnet session with the IP address you just assigned to the management port.
You now have the management port configured with the appropriate IP address.
7. Connect the management port cable to your Ethernet network.
8. Connect GE1, GE2, 10GbE1, 10GbE2, FC1, and FC2 cables.
If necessary, repeat these procedures to configure the second blade.
2.3
Install SANsurfer Router Manager
Install the SANsurfer router management software on your workstation. The default password is
config.
1. Connect to the iSR6250 router.
2. Configure the iSCSI ports for your blade(s): IP address, subnet mask, and gateway.
2.4
Enable Virtual Port Groups
Each iSR6250 router blade has one Virtual Port Group (VPG) enabled by default, which gives the
iSCSI hosts access to 256 LUNs per EMC array. If you want the iSCSI hosts to access more than 256
distinct LUNs from a single EMC Array, you must enable and configure additional VPGs. Each configured
VPG gives the iSCSI hosts access to an additional 256 LUNs from each EMC array.
VPG 1 is the primary virtual port group and cannot be disabled. Enabling extra virtual port groups
creates additional logical FC HBA initiator ports on the fabric. You can register these additional ports and
assign them to their own Storage Groups in your EMC Storage Array.
With all four VPGs enabled, a single iSR6250 blade can access up to 1024 LUNs from a single EMC
array, using four Storage Groups. You can easily configure additional VPGs at a later date; therefore, you
do not need to initially configure more VPGs than necessary. QLogic recommends that you enable the
same virtual port groups on each blade. For more details about Virtual Port Groups, refer to the
“Configuration” chapter of the iSR6250 Installation Guide.

Verify Access to LUNs
Verify that the iSR6250 has access to LUNs on the storage array(s) by expanding any Virtual Port
Group and FC Target WWPN under the FC Discovered Targets tree of the appropriate iSR6250 blade.
Figure 2-13. Select FC Target Device
NOTE:
After modifying LUN Presentation / Storage Group on your EMC Storage Array, you might need to
disable, then re-enable the blade FC ports for the router to discover the access changes.
To view the LUNs, select the device (as shown in Figure 2-12 or enter the show luns command in the
CLI.
2.11
Discover iSR6250 iSCSI Ports
Use the iSCSI software on host machine(s) to discover one of the iSR6250 iSCSI ports on each of the
iSR6250 blades. This creates initiator entries in the iSR6250. The iSCSI hosts should show a logged
out status.
To verify a successful discovery, you can use either the iSR6250 CLI commands or the SANsurfer
Router Manager.

Configure Per-LUN Host Access
The iSR6250 allows multiple iSCSI initiators to connect to a single FC target through a given VPG.
Controlling individual LUN access for each iSCSI host requires LUN mapping devices connected through
the iSR6250.
To allow the iSCSI host access to each LUN, you must configure the iSR6250 using either the
SANsurfer Router Manager or the CLI. If you do not want to control per-LUN Host access, but want to view
all LUNs on all iSCSI hosts, you can disable the LUN masking feature of the iSR6250. For details, see
section 4 of the iSR6150 Installation Guide.

Upon logging into a Fibre Channel target WWPN, an iSR6250 blade will present an iSCSI target for
iSCSI initiators to connect to. This target is defined by its iSCSI Qualified Name (IQN) string. To connect
iSCSI initiators to Fibre Channel targets through the iSR6250 correctly, it is important to understand the
composition of the iSCSI target IQN string.
The following example shows the anatomy of a sample IQN string from an iSR6250 router blade:
Notice that the IQN string does not contain any information about which iSR6250 physical iSCSI port
you are connecting to. The iSCSI host and the iSR6250 handles iSCSI load balancing and failover. If you
are using PowerPath® or other multi-pathing software, make sure the iSCSI hosts log into the iSCSI target
for both Storage Processors on the Storage Array.

To display the complete list of IQN strings the iSR6250 presents, use the show presented_targets
CLI command. In the following example, the iSR6250 blade 1 is connected to two Fibre Channel port
WWPNs with three Virtual Port Groups enabled.

Table 3-1. Frequently Asked Questions (FAQs)
Question
Answer
I’m using a serial port to connect to the iSR6250, but
either the console will not come up, or the console displays unusual characters.
Make sure you are using a regular RJ45 patch cable with
the correct RJ45-to-serial port adapter (not a null modem
cable). Verify that your serial port is set to 115200 baud,
8 bit data, no parity, and no flow control.
I’ve connected the FC ports of the iSR6250 to the target.
The target is online, but no LUNs are displayed.
Make sure you have configured your storage to present
LUNs to the iSR6250 Fibre Channel ports that are connected to the array.
The iSCSI initiator does not discover any targets when
the iSR6250 iSCSI port is discovered.
Verify that the iSR6250 has an online Fibre Channel target. You can do this using the SANsurfer Router Manager or by entering the show targets CLI command.
The router will present online Fibre Channel targets only
to iSCSI initiators.
When trying to login to an iSCSI target, a login failure or
session status related error message displays.
Make sure you are connecting through the right adapter
on your initiator. In the Microsoft® iSCSI initiator, click
Advanced after you select a target and click Login. Be
sure to specify both the adapter and the source IP. If the
login still fails, verify that the iSR6250 has connectivity to
the initiator port using the ping utility on the iSR6250.
