XenServer server availability

Summary

A pool master has detected that the server cannot be contacted and managed.

Causes

A server can be unavailable for many reasons, including:

• The server may be in the maintenance mode.

• A network connectivity problem may exist between the pool master and a pool member.

• The server may have been shut down or has stopped responding.

Resolutions

Consider the following solutions to make the server available:

• Check whether the server unavailability has been planned.

• Check whether you can ping the server.

• Check whether the server has been shut down and start it.

• Check whether the server has stopped responding and reboot it.

• Check your network configuration.

Additional

The pool master has detected that the pool member server cannot be contacted and therefore cannot be managed. Along with the pool member server affected, this alert also lists VMs that were running on the server at the time of last successful check.
