Hello All,
Working on DB2 LUW V10.5.
WE have got add new standby ( auxilary standby) to our existing HADR cluster ( with TSA) .
I can see Multi standby is enabled already ( i.e. "hadr_target_list " already has value on both primary and standby) .
Saying "Multi Standby" is already enabled , we can add or remove additional standby server dynamically.
so currently our system has Primary and one Standby and need to add one new standby.
Way (1)==> wanted to confirm below steps will help to get it done?
- take full online backup on primary
- restore on new Standby ( Auxiliary) and keep in rollforward state
- configure HADR parameters on Auxiliary standby
- configure HADR_TARGET_LIST on primary, principal standby and auxilary standby.
to take 'hadr_target_list' into effect need to stop and start hadr which planning to do as follows -
- stop hadr on Primary [As TSA is enabled, hoping primary will be still responsive and down time requried ]
- start hadr on principal standby as standby
- start hadr on auxilary standby as standby
- start hadr on primary as Primary
so the steps should not need any downtime? please let me know if my assessment will work?
Way (2) ==> Or after just building auxilary standby and updating "hadr_target_list" on all servers ( primary, standby, auxilary) and then just starting hadr on auxilary will help?
Thanks for your time in advance.
Regards
Shashi
