Subject Re: XenServer is disconnected after CS hosts shutdown
Date Mon, 20 Jul 2015 13:24:38 GMT
some questions :

can you please tell ...

1. is your NFS storage or your primary Storage Repository  in connected
mode with no red cross mark on them in xencenter.
2. did you change any passwords on the xenservers ?
3. is the cloudstack web ui up , can you login to the cloudstack web page.
4. *are the zone , pod, or clusters in unmanaged or disabled state ? *
*5. is all the hosts in connected state  ? *
*6. did you run  yum update on host reboot on the cs manager vm ? *
*7. system vms are stateless you can kill them and cs will recreate a new
one .. so dont worry :-) *


*thanks *
*prashant *
