What is the meaning of MDS HA
today i found i issue
we had to management as HA and two firewall as HA also.
i got an license issue ( to solve that issue we have to replace all MGMT box with new )
to replace HA management we have 2 options.
1. we will put 2 new mgmt box as two new standby MGNT in mds level and after that we will promote one of the new box as primary. ( but we are not recommended on that way TAC engineer said)( he also said the is nothing way to do promote secondary to primary MDS) ( i wanna ask for option 1 so if there is nothing way to promote secondary to primary MDS , why we had deployed management as HA , if primary fail we cant promote secondary to primary, so secondary MDS is necessary cost. other question is can we put more than one standby mds on checkpoint Gaia operation system.
2. is we will export database to new one and then sync to seondary new one
the issue is customer only left total 30GB(total 3TB) space on mgmt we cant delete can log or backup cause it's and critical environment. if we do export command, the space will full or not.
customer also use VSX.
i want to know is what is the recommendation of using export database command . can we done that on 30gb space.
