Failover MDM
Hi,
Any idea how to enable the failover MDM ? I saw the mdm_failover binary on MDM server, managed to bring it up but when I did a simulation with secondary MDM goes down, the failover didn't do anything. Can't find the manual either for mdm_failover.

Hi,
If the goal is to switch the MDM to the Secondary MDM, you can do this through the CLI:
If you are talking about MDM_failover explicitly, then that is a little more involved given additional standby or tie-breaker MDMs that can be configured and this is a good manual that discusses that scenario:

That might be due to the credentials associated with your account. Send me a direct message offline and I can send it to you.

Hi,
Unfortunately No
I don't get the documentation that I need yet

Hi,
Finally I can get the documentation and start configuring as stated. However, in all my MDMs server I've already run the script but when I tried to shutdown one of the MDM, the service doesn't seems to run. Not even trying to change the cluster to single mode. It just won't do anything.
Anything that I miss maybe?
Regards,Dondy

Since you tried this before specifying the failover MDMs I would suggest deleting the service, see bottom of page 3, and than attempt to rerun the command. Make sure that you are enter the IPs correctly in the CLI too. If you have a single IP per MDM it should look like this.
[mdm1_ip]+[mdm2_ip]
If you have multiple IPs per it should look like
[mdm1_ip1,mdm1_ip2]+[mdm2_ip1,mdm2_ip2]

[root@scaleio-01 bin]# scli --query_cluster
Mode: Cluster, Cluster State: Degraded, Tie-Breaker State: Connected
Primary MDM IP: 10.211.55.30
Secondary MDM IP: 10.211.55.33
Tie-Breaker IP: 10.211.55.32
Management IP: 10.211.55.30, 10.211.55.33
Name: N/A
[root@scaleio-01 bin]#
State Degraded is because I turn off the secondary MDM to simulate crash.

Hi,
Thanks for the reply.
Yes, I meant the mdm_failover explicitly. However, I can't access link that you've given me
