Serving Storage to the iSCSI Initiators from the SR2122 over IP

during driver installation to minimize that problem. The files can be used to automatically
activate certain system features after the iSCSI devices are present. Please refer to the
instructions at the beginning of the actiscsi.vbs file for detailed installation information and
procedural steps.
Once the iSCSI driver is installed, the IP host will proceed with a discovery process for iSCSI
storage devices as follows:
1. The iSCSI driver requests available iSCSI targets from the SR2122.
2. The SR2122 sends available iSCSI target names to the IP host.
3. The IP host logs in to the iSCSI targets.
4. The SR2122 accepts the IP host login and sends target identifiers.
5. The IP host queries targets for device information.
6. Targets respond with device information.
7. The IP host creates a table of internal devices.
The HP StorageWorks iSCSI Driver for Microsoft Windows 2000 and Windows 2003 uses
Windows 2000 network services to connect to iSCSI remote target nodes that are defined
using the iSCSI control panel applet.
Using the “Status” button of the iSCSI Configuration Control applet can retrieve status of the
iSCSI connections to the remote target nodes and targets. Each responding remote target will
show up with its IP address, connect state, and target name or alias.
The possible connect states are:
Enter Window’s Disk Management application and it should now report new disks and ask to
write a signature. At this point you would treat these drives as you would any locally attached
disk (create partition, format, etc.).
Table 5: Possible Connect States
NOTINIT
TCP connection CLOSED, iSCSI not initialized
UP
TCP connection ESTABLISHED, iSCSI not initialized
DOWN
TCP connection CLOSED, iSCSI down
LOGIN
TCP connection ESTABLISHED, proceeding with iSCSI login sequence
ACTIVE
TCP connection ESTABLISHED, iSCSI active
BREAK
TCP connection CLOSING, iSCSI going down
WAIT
TCP connection ESTABLISHED, iSCSI waiting for previous targets to
complete login sequence
DISABLED
TCP connection permanently CLOSED until after a reboot. This state is
entered if the user chooses to immediately disable all connections to an IP
address being removed with the iSCSI control panel applet.
HELD
TCP connection CLOSED because of certain types of login failures. Login
attempts will resume after receiving notification that new targets are present
or by using the Relogin button on the iSCSI control panel applet.
