In an SRDF environment, when the status of an RDF device changes Potential Data N/A (for example, an R2 device becoming read/write enabled due to a Unavailability split command), the storage system issues a Unit Attention. If this occurs when a UNISYS Dorado host is starting up and bringing the path to the storage system online, the host generates a ABNORM error and fails to start.

In an SRDF environment, the output from the A7,RASN inline command does not show all ports and all groups. This is due to the system incorrectly updating the information it holds on paths. This has the potential to cause problems when deleting groups as that action can cause paths that are still operational to be reset.

Microsoft 2012 (Win8) ODX Support
Due to the increase in track size (from 64K to 128K) in HYPERMAX OS VMAX3 Family arrays, Windows 2012 issues ODX extents 5977.497.471 that do not align on these boundaries. As a result, offload copies are failing with a check condition resulting in the host being forced to perform a software copy. As a result, you may experience a longer then expected time for the copy request to complete.

Ports on the 16 Gb/s Fibre Channel front-end I/O module may take longer than expected to recover if a link bounce occurs during active I/O. This issue may occur if the I/O module is running any of its supported speeds (4, 8, 16 Gb/s) and applies to SRDF and host I/O traffic.
