Notes

_____________________________________________________________

In order to upgrade a High Availability

system with a minimal loss of service we

first need to SPLIT the two cores so we

can login to the Standby side.

Once the SPLIT command has been

issued you will see the Standby system

initialise offering the overlays to login to.

(When the two cores are synchronised

the standby will be running background

tests and the overlays/login will not be

available although you can login with

PDT).

The ACTIVE core is still processing

calls for the system but will no longer try

to synchronise with the standby system.

At this point if we were carrying out an

upgrade we would now install the

upgrade to the Standby system and

check its validity before bringing it into

service.
