HP-UX 11i: measurably better TCO!
 Advisory Information

RELEASE DATE: 21 April 2004

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 is sufficient.


This problem may occur on all V5.1A and V5.1B HP Tru64 UNIX systems running  running emx drivers prior to Version 2.12.


RESOLUTIONbr> AAn ERP containing the latest version of the emx driver (V2.14) is available from the following locations:
