The product Securepath, version A.3.0F.02F.00F or higher, is also required to be
installed along with this product on the system, for enabling these features.

Summary of Change
Summary
DUMPAAEnable provides the following features:
• Active path configuration:
An Active-Active device can be configured as a dump device through any of the paths
to the device. If the path through which dump configuration is being attempted is
currently offline, then an alternate active path will be used for configuration. The
alternate path that is used for configuration can be displayed with the help of the
new option, -l, to crashconf (1M). If all the paths to the device are offline, then
configuration will fail.
• Failover/Path change:
If the path that was used for dump configuration goes offline, then an alternate
active path will be automatically configured for dump. The current active path
configured for dump can be displayed with the help of the -l option to crashconf
(1M).
• Duplicate device identification:
An Active-Active device will have multiple device special files (/dev/dsk/c#t#d#
files), one corresponding to each path to that device. Re-configuration of an existing
Active-Active dump device through an alternate device special file will be detected
and the configuration will fail.
• Display live and configured path:
The new option, -l, added to crashconf (1M) can be used to display both the user
configured path and the current active path configured for dump.
• LUN Collision:
Dump devices under LUN collision are removed from the dump device list to avoid
dump corruption.
Impact
Installing this product without the SecurePath Version A.3.0F.02F.00F will have no
effect. Along with Securepath, this product increases the availability of dump.
Compatibility
This product has no impact to compatibility. A new option has been added to crashconf
(1M) to return additional information pertinent for Active-Active devices.
