Overview iSCSI protocol The HP iSCSI protocol transports block-level storage requests over TCP connections. Using the iSCSI protocol, systems can connect to remote storage and use it as a physical disk although the remote storage provider or target may actually be providing virtual physical disks. HP Accelerated iSCSI supports all targets that are certified and supported by Microsoft iSCSI Software Initiator.

Go to the HP website (http://www.hp.com). 2. Click Software & Driver Downloads from the left menu bar. 3.
2. Select Enable iSCSI Device to enable iSCSI on the multifunction adapter. iSCSI cannot be enabled on the device if the adapter is in an Automatic, 802.3ad Dynamic with Fault Tolerance, or SwitchAssisted Load Balancing with Fault Tolerance (SLB) team. 3. (Optional steps). Type a user-defined MAC address for the iSCSI device in the Locally Administered Address box. The default MAC address is used if an address is not entered.
4. Click iSCSI IP Settings. The iSCSI IP Settings window appears so that you can specify how the IP Address is obtained. 5. On the iSCSI IP Settings window, select one of the following: a. Obtain an IP Address automatically. This is the default. If this option is selected, DHCP is used to acquire an IP configuration for the iSCSI device. b. Use the following IP address. This option allows you to specify the IP configuration for the iSCSI device.
iSCSI Devices tab The iSCSI Devices tab lists all HP ProLiant Gigabit Ethernet Multifunction server adapters that are iSCSI enabled. A sample iSCSI Devices tab for Windows Server 2003 is shown below. If you upgrade the Network Configuration Utility (NCU) to version 8.20 or later, the following team types are converted to the Transmit Load Balancing (TLB) team type if they include an iSCSI-enabled adapter. • Automatic • 802.
1. Select an HP Multifunction Adapter in the NCU Main window or the iSCSI Devices tab and click VLAN (802.1Q) to display the VLAN tab. Alternatively, hold down the Alt key and enter v to display the VLAN tab. The iSCSI VLAN/QOS (802.1p/Q) window displays the following information: o iSCSI VLAN Id. Shows the identifier value used for the iSCSI VLAN device. o iSCSI VLAN Name. Shows the descriptive name for the VLAN ID.
2. To create an iSCSI VLAN, click Add to open the VLAN Properties dialog box. Only one VLAN can be created per iSCSI device. a. In the VLAN Name box, type a descriptive name. b. Click VLAN Id and select an identifier value. c. Click OK. 3. To modify an existing iSCSI VLAN, select the VLAN Id or Name and click Edit to open the VLAN Properties dialog box. 4. To delete an existing iSCSI VLAN, select the VLAN Id or Name and click Remove. 5. Click OK to save all changes.
2. Select the Information tab to display the Multifunction Adapter Properties Information window. The Detailed iSCSI Information window displays the following: • Current MAC Address. The current MAC address for the iSCSI device. • iSCSI Driver Name. The name of the driver for the iSCSI device. • iSCSI Driver Version. The version of the driver for the iSCSI device. • Default Gateway. The default route for the iSCSI device. • Subnet Mask. The subnet mask (dotted decimal) for the iSCSI device.
iSCSI Statistics tab To view the iSCSI statistics for the selected adapter: 1. Select an HP Multifunction Adapter in the NCU Main window and click Properties to display the Multifunction Adapter Properties Settings tab.
