Hello Duncan,
first of all thanks for your answer, for your information I was able to recover and rebult it by recovering from backup, but what I did was to execute b1h_switcher.sh to failover without stopping anything first, and failover took place correctly to secondary, after this I executed again b1h_switcher.sh to failover again to the first server and then it crashed.
If I have a chance I will make some tests again and if it fails I will post it again and we can discuss about it.
Thanks and regards.
