We have a customer with two sites with Single CM cluster running 4.1.3 and ER 1.3.1a and BW between sites is 1GB.
Site 1 - CM Pub,Sub1 and 2,ER Pub& Sub
Site 2 - CM Sub3 & Sub4, new ER??
At site 1 they already have a ER group/cluster.They can use the same ER group at site 2 even though site 2 is in different area code and different PSAP.
But they already bought the hardware from different vendor and they want to use it for redundancy in case if the WAN is down.
Now my question is at site 2 how should we install the new ER server and have failover option in case WAN is down
1.Install as a new subscriber (This I'm not sure we can install more than subscriber on a ER group/cluster)
2.Install as a new publisher.According to Cisco Doc we can install new ER group if it is differnt PSAP and need to support more devices and make one ER cluster.This part I'm not sure how to configure it two ER groups make it as one ER cluster.
3.Since CM PUB is at site 1 can we install this ER as publisher?, I'm assuming it will work because they have 1GB BW.
Has anyone come across this scenario or implemented similar design?
Please advise and any help will be really apprecaited..
Are you getting this error “Installer User Interface Mode Not Supported. The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The value UI mode identifiers...
The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
