4 Verifying cabling between MSA2212fc G1 controller
ports and zoned SAN switch for MSAs connected to HP
SFS G3 servers
This section describes how to verify the cabling between MSA2212fc G1 controller ports and the
zoned SAN switch for MSAs connected to SFS G3 servers so they work even under single controller
failure in any of the controller pairs.
The MSA controller and the SAN switch cabling diagram as shown in the HP Scalable File Share
User Guide G3.2-0, Section 1.3.1 Hardware Configuration, Figure 1-2 Server Pairs is only functional
for MSA2000fcG2 or G3 product families. This cabling does not work as expected by HP SFS
G3 with MSA2000fc G1 (MSA2212fc) in the event of single controller failure in any of the controller
pairs because:
• MSA2000fc G1 (MSA2212fc) does not support ULP. LUNs are mapped to the WWNs of the
owning controller.
• The WWNs failover in crossed mode. Controller A port 0 fails over to controller B port 1 and
vice versa. The port carries the LUN along with it.
For HP SFS G3 controller failover with MSA2000fc G1 (MSA2212fc), the cabling must be crossed.
Connect A0 and B1 to one zoned SAN switch. Connect B0 and A1 to another zoned SAN switch.
For this controller failover cabling configuration, see Figure 3 (page 12).

Although HP recommends using the HP StorageWorks 2012fc Modular Smart Array User Guide
as a reference for MSA cabling, instances of incorrect cabling between s SAN switch and
MSA2000fc G1 controllers (MSA2212 fc) have occurred. If you are using MSA2000fc G1
(MSA2212 fc) with HP SFS G3, and cabling between zoned SAN switches and MSA2212fc
controllers is not crossed for controller failover configuration, contact HP SWD support to correct
your cabling.
