Serving Storage to the iSCSI Initiators from the SR2122 over IP

iSCSI SR2122 Storage Router: Getting Started Guide
Each line will show the Linux host number, channel number, target id number, and logical unit
number, as well as the IP address, TCP port, and iSCSI TargetName. If an iSCSI session
exists, but no LUNs have yet been found for a target, the LUN number field will contain a
question mark. If a TCP connection is not currently established, the IP address and port
number will both appear as question marks.
Kernel Upgrades
Because the driver contains a Linux kernel module, the driver must be rebuilt and reinstalled if
you make any changes to your Linux kernel. To remove, rebuild, and reinstall the driver, do the
following while logged in as root:
make remove
make clean
make
make install
Configuring hp StorageWorks Secure Path for Windows with the SR2122 Storage
Router
Note:
HP Storageworks for Windows is supported with SR2122s in Standalone Mode only. SR2122
HA environments are not supported.
Note:
Note: Only the HSG80 and HSV110 controllers are supported with Secure Path.
With Secure Path configured on a server directly connected to a fibre channel SAN, a LUN is
presented to the server's multiple fibre channel host bus adapters to insure failover capabilities.
With Secure Path running on an iSCSI client the controllers do not detect the iSCSI client NIC
card, but instead, only sees the FC port of the SR2122 itself. With this in mind a pair of
SR2122s are used with each SR2122 connected to a separate FC fabric which in turn is
connected to two out of the four controller ports. Storage is now presented to the two FC ports
of the SR2122 pair.
As mentioned earlier in this guide, normally the storage is presented to a server, but with
iSCSI initiators we must first get the FC storage to the SR2122 pair, then present that storage
to the iSCSI client over IP.
