18 HP StorageWorks Director release notes
Full Volatility
Full Volatility is an optional feature of firmware 06.00.00 and later that is enabled
with a feature key. The Full Volatility feature is designed to support high-security
environments, which require that customer data not be retained by the edge switch
or director after power off.
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 non-volatile
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.
Route management—Preferred Path
Preferred Path can be configured using either CLI or HAFM 08.02.00.
Preferred Path allows you to influence the route of data traffic when it traverses
multiple switches or directors in a fabric. If more than one interswitch link (ISL)
connects switches in a fabric, you can specify an ISL preference for a particular
flow. The data path consists of the source port of the switch or director being
configured, the exit port of that switch or director, and the domain ID of the
destination switch or director. Each switch or director must be configured for its
