Looking for procedure for data mover failover

take a look at server_standby command. For example:



EXAMPLE #1

To create a standby relationship between server_2 (primary) and server_3
(standby), type:

$ server_standby server_2 -create mover=server_3
server_2 : server_3 is rebooting as standby

Before any other actions can take place, the reboot must be complete.

EXAMPLE #2

To activate the server_3 (standby) to take over for server_2 (primary),
type:

$ server_standby server_2 -activate mover
server_2 :
server_2 : going offline
server_3 : going active
replace in progress ...done
failover activity complete
commit in progress (not interruptible)...done

server_2 : renamed as server_2.faulted.server_3
server_3 : renamed as server_2


EXAMPLE #3

To restore server_3 as the standby Data Mover and server_2.faulted.server_3
as the primary, type:

$ server_standby server_2 -restore mover
server_2 :
server_2 : going standby
server_2.faulted.server_3 : going active
replace in progress ...done
failover activity complete
commit in progress (not interruptible)...done

server_2 : renamed as server_3
server_2.faulted.server_3 : renamed as server_2

EXAMPLE #4

To verify readiness of the standby Data Mover, type:

$ server_standby server_2 -verify mover
server_2 : ok
