MDR
In an MDR setup, after upgrading the primary Manager to 11.1, can I switch over to make the primary active or do I have to first stop the secondary?
Trellix recommends you to suspend the MDR pair, upgrade the individual Managers and then resume the MDR pair.
For details, refer to MDR Manager upgrade.
Do I need to do any specific step after the upgrade to re-establish MDR?
No. It works automatically.
After upgrading the Secondary Manager, do I need to import the database to secondary or will that happen when I re-establish MDR?
If you have suspended the MDR pair before the upgrade, the Manager will synchronize after MDR resumes.
Do I need to reconfigure MDR to get primary and secondary into MDR again?
No. The MDR configuration is retained and will work automatically.
In an MDR setup when will I see Switch Over and Switch Back?
Switch Over: Available only when the Primary Manager is active. Clicking this will request that the Secondary Manager be active.
Switch Back: Available only when the Primary Manager status is in standby mode. Clicking this will switch back from the Secondary Manager and make the Primary Manager active.
In an MDR setup when will I see Suspend MDR and Resume MDR?
Suspend MDR: Available only on the Primary Manager when in the active state. Clicking this will instruct the Secondary Manager not to monitor via MDR Status check and to resume MDR only when indicated.
Resume MDR: Available only when the Primary Manager is in the suspended state. Clicking this will resume MDR mode when the MDR is suspended.
