HP StorageWorks Fabric OS 6.3.3d Release Notes (5697-0493, May 2010 - includes all 6.3.0x versions)

Fixed in Fabric OS 6.3.0d
Workaround prior to upgrade:
Bounce ports to recover. However,
note that this is a disruptive
operation.
After upgrading from Fabric OS 6.2.x to 6.3.x, RSCNs are not sent to
all devices the target is zoned with, so hosts are unable to see the target
until all host ports are bounced.
Effective date
April 2010
