Citrix XenServer 6.2 How do I resolve pool issues?

Question

Virtualization

Good afternoon.
There is a pool of 2 servers.
It has a shared datastore connected via iSCSI. Everything was running fine.
It was necessary to import the virtual machine there and when importing, it so happened that the connection with my computer was interrupted.
The car appeared there, but accordingly the curve, the icon is yellow. It was impossible to start it or do anything with it (even delete it
) . She's not on the list either. Everything is kind of OK. But the icon of the second server (slave) turned red (see screenshot). After some time, master followed in his footsteps. XEN-HOST3 server faild errors began to appear in the logs. The pool is working.
Was Enabled ON - disabled and rebooted both pools.
Indicated to the master that he is a master, to the slave that he is a slave.
Did n't help.
Tell me where to drip .... or at least what logs to see.
I looked in /val/log and did not see any crime.
