CM Interchange / Reload

CM Interchange / Reload

CM Interchange / Reload

My virtual CM interchanged and then 1 of the 2 servers reloaded causing a failover to ESS. The links from this location didn't have any outage, but within the farm and storage arrays I feel something caused this. The other teams are combating this theory. Where can I see in the CM logs what the RC was of the interchange? Not sure why after the interchange to serverB that server B then reloaded. Running 6.3.15

From Linux bash - start_date_time-end_date_time one hour window example below

sudo logc -t 20190222:1700-20190222:1800 lxsys | less

below is for matching logfile names 2019-0222*.log and looks for IPSI failures over LAN to CM servers
egrep -i pcd.*sanity /var/log/ecs/2019-0222*.log | less

CM measurements at CM Command: prompt

RE: CM Interchange / Reload

check with your vmware admins if they are doing snapshots that would be the exact outcome

RE: CM Interchange / Reload

We had something similar to this last year. The information below lead to our answer.
Avaya PSN020151u discusses Heart beat timeout, duplication link, snapshots, vMotion. It's a good read. We experienced the heartbeat time out caused by an attempted unmounting of the iso used to build the original OVA. This is the vmware KB link https://kb.vmware.com/articleview?docid=2144053.
