DUMPAAEnable Version B.11.23.0609 Release Notes

Important Information on A-A Dump Devices

Path Failover Time

Path failure is detected and Path Failover is attempted at fixed time intervals. This time

interval is set as part of the Secure Path Active-Active configuration. The default time

interval is 10 minutes.

The autopath display command can be used to find the current time interval that is displayed

as Path Verification Period. The current time interval can be changed using:

autopath set -a <ArrayID> -p <interval>

The dump will fail if a crash takes place after the failure of the A-A device’s actual path and

before the detection of the path failure by Secure Path (before the time interval elapses). See

T2 and T5 in “Scenario for Path Failover” on page 6.

A-A Dump devices after Secure Path Active-Active Removal

On Secure Path Active-Active removal, high-availability features are no longer available. All

A-A dump devices configured as full devices that have changed paths (on path failover) will be

automatically configured back to the original user-specified path.

NOTE The user-specified path is configured irrespective of the status of the path

(Active/Failed).

Duplicate Device Removal on Secure Path Active-Active Load

A dump device configured through multiple hardware paths in /stand/system is detected as

duplicate devices and are consolidated into a single device entry during Secure Path

Active-Active discover in the boot sequence.

Secure Path Active-Active can be set to discover devices on boot using the following command:

autopath discover ON

Duplicate Device Removal on Secure Path Active-Active Discover

Active-Active devices that are configured through multiple paths will be consolidated to one

dump device on manual Secure Path Active-Active discover (autopath discover).

Dump Device Removal on LUN Collision

In the event of a LUN collision of a dump A-A device, the device is removed automatically

from the dump device table. The removal of the A-A dump device is recorded in syslog.
