I installed BES 5.0.3 pair.
The problem is the server can’t make auto failover.
I turned on automatic BlackBerry Enterprise Server failover on BAS
But i see the following:
„Unhealthy Items above the failover threshold line will cause an automatic failover”
„All items above the promotion threshold line must be healthy to allow for an automatic failover”
Can you help me?
Where can i see Unhealthy items?

I've searched but can't find an answer to my quick question, once we have an automatic failover from the primary to the standby the failover mode changes to manual so if there is an issue on the standby the service will not fail back to the primary.
Is there a way to keep the failover mode at automatic?

Hi there; We've a BES 5.0.3 HA implementation in progress, in particular HA BES and HA Attach. (Remote attachment)
We've also got a segmented architecture where the BES servers and ATTACH servers are on two separate subnets (BES SEPARATE FROM ATTACH).
We've tested attachments when moving one of the attach servers to the same subnet as the BES servers which works as promised however when moving to a separate network segment - error message "Attachment Server is Busy" when viewing an attachment on a device.
We have provided connectivity proofs to our contractors including showing that ports 1900 and 2000 have got tcp established to the BES server. We have also manually tested using the tool directly from BES to ATTACH which works perfectly.
We have ensured there are no firewall rules blocking traffic in the way (have tried IP ANY ANY) and ensured windows firewall not enabled (taken care of by actual firewall).
We have run a Wireshark sniff on the packets and seen some strage multicast join packets from each side (from BES and from ATTACH).
Our query is : does anyone know how the HA services work, do the servers use a "multicast join group" request to announce that they're there? If we know how it works perhaps we could find out how to make it work on our required segmented architecture.
We keep getting asked if the ports are open (1900,2000), and have proven that they have.
Thanks in advance.

I have a good question for BlackBerry (aka RIM) Support. If someone decides to use an HA product like NeverFail how does one move the cert from the UDS server on the primary side to the secondary side without having to apply for a second cert whcih would really mess things up?
