Product Description

User Notification of Failover

The MPE System Logs will contain Type 111 log records (subsystem 900) to

document the failover event. Log entries are also created as a result of HAFO

activities including configuration, path verification and path switching. In

addition, the following console error message will be displayed upon failover

and every five minutes thereafter. The repeating message can be turned off with

an MPE "reply" ([CTRL] [A] REPLY or :REPLY).

HIGH AVAILABILITY FAILOVER IS STARTED FOR Ldev# IN DISK ARRAY. NO DATA LOSS

OR CORRUPTION. SYSTEM OPERATION WILL CONTINUE.PLEASE PLACE SERVICE CALL SOON.

ACKNOWLEDGE HAFO FAILOVER IN DISK ARRAY FOR Ldev# (Y/N)?

After a HAFO event, system I/O activity resumes via the alternate data path.

There are no limits to the kinds of normal I/O that can be processed on the

alternate data path. However, throughput may be affected since I/O is shared

with bus activities from other Ldevs configured for that bus.

For additional information, see the Chapter 6, "Recovering From a Failover."
