HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 22

The feature configures a switch or director so that no frame data is stored after a power
off. Without Full Volatility, if the switch or director experiences a fault condition, a dump
of the embedded memory space is captured into nonvolatile memory. This dump retains
the last 30 frames transmitted from and last four frames transmitted to the embedded port.
With Full Volatility installed, this dump does not occur when a fault condition occurs.
Although this limits the amount of diagnostic information available for potential problem
resolution, the vast majority of problems are typically resolved without the dump files.
Contact your sales representative to purchase a feature key for Full Volatility.
CLI threshold alerts
With firmware 06.00.00 and later, the CLI allows you to set and monitor Throughput
Threshold Alerts (TTAs).
CLI show.eventLog command
With firmware 06.00.00 and later, the CLI show.eventLog command has been
enhanced. The command now displays a Link Incident log and Event log.
MIHPTO value
With firmware 06.00.00 and later, the internal Missing Interrupt Handler Primary Time
Out (MIHPTO) value has been changed from 15 seconds to 3 minutes.
EWS enhancements
With firmware 06.00.00 and later, EWS enhancements include support for managing
the SANtegrity Binding feature and Enterprise Fabric mode, and providing the Link
Incident log and the Open Trunking log.
Preferred Path support
With firmware 07.00.00 and later, this allows users who are not using HAFM to
configure preferred data paths through the EWS interface. A preferred path is an ISL
data path between multiple fabric elements (directors and switches) that users can
configure using the source and exit ports of the origination fabric element, and the
domain ID of the destination fabric element.
Configuration Backup
With firmware 07.00.00 and later, this allows users to save switch configuration settings
to a standard XML format file, compatible with both HAFM and the Configuration
Backup and Restore (CBR) utility. Customers can easily save configuration settings when
switch configuration is accidentally modified or at hardware failure. A restore function is
not yet available in EWS, but is planned for a future release. In the interim, you can use
the complimentary CBR utility to restore configurations settings.
