Systems using emx drivers prior to Version 2.11 will hang if the SAN
configuration change notification messages are missed by the driver.
This situation can occur when a SAN configuration change occurs and HP
Tru64 UNIX attempts to process the fabric notification event. The
problem within the emx driver may result in HP Tru64 UNIX missing the
notification and causing the system to hang and log a long continuous
stream of fabric sequence timeouts to binary.errlog.
If the system is configured with the MSA1000 or XP Storage
Controllers, there is an additional problem that is fixed with
Version 2.12 of the emx driver. Customers running these
configurations should upgrade to emx driver Version 2.12. If you are
not running this configuration, then running emx driver Version 2.11
