How to find the status of a PME redundant system in XenCenter

Issue
What command gives information about the status of a PME system installed on redundant servers using everRun from Stratus Technologies (Marathon).  The information indicates which server is the master and whether both servers are online or not.

Product Line
everRun, XenCenter, eAC
Power Monitoring Expert (PME)

Environment
XenCenter

Cause
A power monitoring system, PME, is installed on two servers to account for redundancy.  For some reason the redundancy is not working; for example one of the servers could have gone offline.

Resolution
*Warning: Installation and maintenance of XenCenter should only be performed by qualified, competent personnel that have appropriate training and experience. Failure to follow the instructions will result in permanent damage to the system.

1. Open XenCenter
2. Go to 'Console' tab
3. At the prompt, type ev host-list and press 'Enter' to run the command


Below is an example:

[root@ION2 log]# ev host-list

               host-name ( RO): ION1
               host-role ( RO): Slave
        name-description ( RO): Default install of XenServer
