We have two site: A and B. In each of them there are two hyper-v 2008 r2 clusters – cluster LAN and cluster DMZ.
Veeam server is on the cluster LAN in site A. Version of Veeam B&R is 18.104.22.168 (with patch 3).
There is Cisco ASA between clusters and sites. But all necessary ports are open for the Veeam.
Sometimes there is a replication error of the two machines:
- Code: Select all
Unable to subscribe to guest processing components: RPC function call failed. Function name: [IsSnapshotInProgress]. Target machine: [172.17.65.32]. RPC error:The RPC server is unavailable. Code: 1722. Unable to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Veeam application-aware processing). Details: Failed to prepare guests for volume snapshot. Unable to allocate processing resources. Error: Unable to allocate resources for taskId: '04f68c28-abcc-4ace-8885-909564413ab9'
Look at the pictures (ASA):
Where: 10.1.32.23 – VEEAM server, 172.17.65.32, 172.17.65.31 – replicated virtual machines (Win2008 r2).
So Veeam uses strange ports that are not in the documentation - 23834, 1071, 20688, 1056.
Does anybody met with same problem?
