Planning server connections to management groups
Add each server connection that needs access to a volume to the management group containing
the volume. After you add a server connection to a management group, you can assign the server
connection to one or more volumes or snapshots. For more information, see

Planning iSCSI server connections to management groups
NOTE:
A server connection can be configured for both iSCSI and Fibre Channel connectivity.
However, there must be only one connection to a volume by a server.
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 235)
.
•
To use iSCSI VIP load balancing, you must use a compliant iSCSI initiator. Verify the initiator
compliance by going to the HP LeftHand 4000 Storage Compatibility Matrix at:
http://www.hp.com/go/LeftHandcompatibility
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 LeftHand Storage, including load balancing
and CHAP authentication, see

Description and requirements
Item
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
Not used for the Application Aware Snapshot Manager
on Windows.
Controlling Server IP Address
Required for the Application Aware Snapshot Manager
on VMware. IP address of the Microsoft Windows server
that is hosting the vCenter Server.
Optional for using VSS on Windows servers.
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
