7.10 MSA2000fc G1 incorrect MSA cabling between MSA2212fc
controllers and SAN switches with zoned SAN switch.
The MSA controller and SAN switch cabling diagram as shown in (page 18) is only functional
for MSA2000fc G2 or G3 product families. This cabling does not work as expected by HP SFS
with MSA2000fc G1 (MSA2212fc) in the event of controller failure because:
• MSA2000fc G1 (MSA2212fc) does not support Unified LUN Presentation (ULP). The 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 configuration, see
Figure 7-1 “MSA2000fc G1 cabling” below.
Figure 7-1 MSA2000fc G1 cabling
Although HP recommends using HP StorageWorks 2012fc Modular Smart Array User Guide as a
reference for MSA cabling, there are some instances where this guide does not provide the correct
MSA cabling for failover configuration. If you are using MSA2000fc G1 (MSA2212 fc) with SFS
G3, verify that cabling between zoned SAN switch and MSA controllers is crossed as
recommended for controller failover configuration.
If assistance is needed, contact HP support.
7.11 Standby server does not take over neighboring resources
When the operator simulates a PSU failure by powering off an OSS node, losing the operating
system and iLO2 on that node, the standby server does not take over the neighboring resources
due to incomplete stonith operation (destination iLO2 is unreachable). This is the limitation of
Heartbeat. To workaround this issue, reboot the remaining peer to bring up the resources.
