RE: [Xen-API] xe vm-list on slave server hang after unplugging master server network cable

[Anthony Xu <anthony@xxxxxxxxx>]

Hi Dave,

Will typing xe pool-recover-slaves in the new master make other servers
slaves to this new master? 

Then we don't need to type Xe pool-emergency-reset-master on each slave.

Thanks,
Anthony
