Vault Recovery

[Phin_Wells]

I have one mailbox and one journal Vault server in each of our two datacentres, both are on physical hardware rather than VMware. We run an active passive configuration; so currently the mbx and journal vault servers are live in datcentre 1. We'll use USL to failover the services for both Vault servers to the other datacentre; this has been tested and is working as we expect it to. However this failover assumes the source servers, so the servers currently in datacentre 1 are online. what is the recovery procedure if we lose the two servers in datacentre 1 ?  

All our indexes and partitions are hosted on netapps that are replicated and the SQL dbs are mirrored so we can recover all the user data.

Thanks

Hi Phin

Do you use DNS-aliasses for the EV-servers?

Seeing you use USL you should.

Switch the aliasses, then do USL

example:

EV1 = server1

EV2 = server2

EV3 = server3

EV4 = server4

EV1 and 2 in DC1 which failes

Set alias EV1 to Server3

Set alias EV2 to Server4

make sure data is replicated etc.

USL on EV1 (then running on server3)

I think....

Hi,

Thansk for this; is this failover step still valid if the live nodes become unavailable? So in a DR scenario where you lost connectivity to a datacentre would the USL procedure of flipping the DNS names then running the USL process work?
