An engineer is performing failover testing on an FC-attached, dual-controller SC8000 system. The engineer
notes that the customer’s Windows 2008 R2 servers experience I/O errors. The RHEL and ESX servers
experience no problems.
A11 FC HBA timeouts are configured per Dell best practices. The Windows servers that are experiencing
issues have had no OS-level configuration changes related to SAN storage. All servers use the same FC fabric.
What is causing the connectivity loss during failover?
An incorrect OS type was selected when the Windows server objects were created.
The windows Disk TimeoutValue is NOT set correctly.
NPIV is NOT enabled on Storage Center FC local ports.
The FC cables plugged into the Windows servers have RX and TX reversed.
