Failover is automatic and will allow applications to continue uninterrupted.
In the event of failover, repeated warnings appear on the system
console indicating a failover event has occurred. The warning specifies
which high availability array ldev has experienced a failover event.
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)?
The warning message will be displayed on the console every five minutes until
the operator does a [CTRL-A] reply. In addition to the console warning
message, a failover generates entries in the I/O and system logs.
The HAFO console message allows you to monitor the failure event. There is also
a new command HASTAT, that allows you to display status for all HAFO
configured ldevs at anytime. HASTAT displays the following information:
LDEV # of arrays configured for failover
Primary and alternate path information
Status of primary and alternate data path for doing I/O (failover
and possible cause of data path failure)
 |
NOTE: The HASTAT command only reports on ldevs that are in the
HAFOCONF file in the group from which the system was booted.
