Configuring the SR2122 iSCSI Storage Router in a SAN
13iSCSI SR2122 Storage Router: Getting Started Guide
Configuring the SR2122 iSCSI Storage Router in a SAN
Configuring the SR2122 in a SAN takes on five distinct steps or sections:
■ Setup/configuration of the SR2122 itself
■ Adding the SR2122 to a SAN – standalone or clustered
■ Serving storage to the SR2122 from the storage arrays over Fibre Channel
■ Serving storage to the iSCSI Initiators from the SR2122 over IP.
■ Setup/configuration of the iSCSI Initiators
SR2122 Setup
The SR2122 can be configured either as a standalone or clustered device. In Standalone Mode,
as the name implies, the SR2122 does not have failover capabilities to other SR2122s. In
Clustered Mode up to four SR2122s can be used as failover when presenting storage to iSCSI
Initiators.
Note: A Standalone SR2122 can be added to a SR2122 Cluster without re-initializing the
standalone router to preserve its configuration.
For further SR2122 configuration details, please read “HP StorageWorks iSCSI storage router
2122 User Guide PN: 304835-002” Chapter 5 – Configuring the Storage Router.
Whether adding SR2122’s in Standalone or Cluster modes its important to know the WWPN
of the fibre channel ports as they are needed for configuring both SAN zoning and Selective
Storage Presentation (SSP).
To find the WWPN of a FC ports using the SR2122’s CLI enter:
