Serving Fibre Channel Storage to the SR2122
16 iSCSI SR2122 Storage Router: Getting Started Guide
Serving Fibre Channel Storage to the SR2122
Once the SR2122 is properly configured, connected and zoned within the SAN, the next step is
to present storage to the router.
Where normally the storage is presented to a server, we must first get the FC storage to the
SR2122, then we have to present that storage to the iSCSI Initiators over IP.
As previously mentioned, the SR2122 FC ports look like a typical Fibre Channel Host Bus
Adapter to the storage array. Depending on the storage array it’s now a matter of creating
LUNs and presenting them to the SR2122’s FC port. This section describes how to serve
storage from each supported storage array – MSA1000, RA/MA8000, ESA/EMA12000,
Enterprise Storage Array, VA and XP – to the SR2122.
The assumption is the reader is not only experienced in the initial setup of these storage arrays
but also in the creation of storage volumes or LUNs. This section describes the presentation of
these LUNs to the SR2122. If not, if is suggested to read the configuration/user/reference
guides for the storage array in question.
Please read “HP StorageWorks SAN Design Reference Guide – September 2003 Part Number:
AA-RMPNJ-TE” for the latest HP storage configurations and rules.
Presenting MSA1000 LUNs to the SR2122
MSA1000 storage volumes must be pre-configured before the LUN(s) can be detected and
recognized by the SR2122. The MSA1000 can be configured either through its serial port or
through the Array Configuration Utility.
Whatever method is chosen we must now use the MSA1000’s selective storage presentation
(SSP) commands to restrict access to volumes that are to be served to the SR2122.
Without HP Secure Path, the MSA1000 is supported with the SR2122 accessing only one
MSA controller port. This restriction disables controller failover protection.
First, the Show Connection command will determine if the MSA1000 storage array is aware of
the SR2122 FC port(s).
MSA1000> show connection
Connection Name: “”
Host WWNN = 10000002-3d071bc0
Host WWPN = 28000002-3d071bc0
Profile Name = Default Profile
Unit Offset = 0
Controller 1 Port 1 Status = Online
Next, to enable an ACL, the MSA1000 Volume Unit must be assigned to the SR2122's FC port
WWPN. For example, a Show Unit command may display:
MSA1000> sho units
Unit 1:
In PDLA mode, Unit 1 is Lun 2; In VSA mode, Unit 1 is Lun 1.
Unit Identifier:
Volume Status: VOLUME OK
5 Disk(s) used by lun 1:
