11.0 HP StoreVirtual Storage User Guide (AX696-96275, December 2013)

Prerequisites
• Each server must have an iSCSI initiator installed.
• The initiator node name, or iqn string, for the iSCSI initiator. See “iSCSI and CHAP
terminology” (page 243).
• To use iSCSI VIP load balancing, you must use a compliant iSCSI initiator. Verify the initiator
compliance by going to the HP StoreVirtual 4000 Storage Compatibility Matrix at:
http://www.hp.com/go/StoreVirtualcompatibility
CAUTION: Using a noncompliant iSCSI initiator with load balancing can compromise volume
availability during iSCSI failover events.
Characteristics of iSCSI server connections
For detailed information about using iSCSI with HP StoreVirtual Storage, including load balancing
and CHAP authentication, see “HP StoreVirtual Storage using iSCSI and Fibre Channel” (page
241).

Description and requirementsItem
Name of the server that is displayed in the CMC. The server
name is case sensitive and cannot be changed after the
server is created.
Name
Optional: Description of the server.Description
If you are using application-managed snapshots, you must
assign a controlling server IP address to each server you
Controlling Server IP Address
create in the CMC. See “Using Controlling IP addresses”
(page 200).
Allows the server to connect to the client using an iSCSI
initiator.
Allow access via iSCSI
The name, or iqn string, of the iSCSI initiator. Open the
iSCSI initiator and look for the string there. You can copy
the string and paste it into the field.
Initiator Node Name
Configures iSCSI load balancing for the server connections.Enable load balancing
Enables initiators to log on to a volume without
authenticating their identity.
CHAP not required
Requires initiators to authenticate before they can log on
to a volume.
CHAP required
Adding an iSCSI server connection
1. In the navigation window, log in to the management group.
2. Click Management Group Tasks, and select New Server.
3. On the iSCSI tab, enter a name and optional description for the server connection.
4. If you are taking application-managed snapshots, enter the Controlling Server IP Address.
5. Select Allow access via iSCSI.
6. If you want to use iSCSI load balancing and your initiator is compliant, select Enable load
balancing.
