2 You can use the Discovery Domains feature to group certain Initiators
with Targets with specific access:
a
Go to iSNS Server Properties
→ Discovery Domains tab→ click
Create
→ enter a name for the Discovery domain→ select Add.
b
The Add registered Initiator or Target to Discovery Domain screen
appears. Select the specific Initiators and Targets that you want to
configure and click OK.
3 You can configure multiple Discovery Domains in the iSCSI network.
The domains are listed in the Discovery Domain Sets tab. The Discovery
Domain Sets tab displays Default DD and Default DDS options. You can
create any number of groups as required.
Best Practices for Efficient Storage Management
Storage Manager for SANs
Storage Manager for SANs is a Microsoft Management Console snap-in that
system administrators can use to create and manage the logical unit numbers
(LUNs) that are used to allocate space on storage arrays in both Fibre
Channel and iSCSI environments. Storage Manager for SANs is deployed
through a conventional snap-in and can be used on storage area network
(SAN) based storage arrays that support Virtual Disk Server (VDS) using a
hardware VDS provider. Due to hardware, protocol, transport layer and
security differences, configuration and LUN management differ for the two
types (iSCSI and Fibre Channel) of supported environments. This feature
works with any type of Host Bus Adapter (HBA) or switches on the SAN. For a
list of VDS providers that have passed the Hardware Compatibility Tests
(HCT), see the Microsoft storage website on www.microsoft.com/storage.
LUN Management for iSCSI Subsystems
For iSCSI, a LUN is assigned to a Target—a logical entity that contains one or
more LUNs. A server accesses the LUN by logging on to the Target using the
server's iSCSI Initiator. To log on to a Target, the Initiator connects to portals
on the Target; a subsystem has one or more portals, which are associated with
Targets. If a server's Initiator is logged on to a Target, and a new LUN is
assigned to the Target, the server can immediately access the LUN.
