vCenter reports no utilization on server, but VMs still run. Can't snapshot.
I have the distinct feeling rebooting the ESXi server will fix this, but right now we have seen/are seeing this:
1. vCenter reported it couldn't talk to blade 1 in our IBM blade center. But VMs never went down.
2.There are no active errors showing in vCenter for the blade.
3. Under the Virtual machines Tab, it shows Host CPU and Host mem and Guest Mem as zeros... it sees no activity.
4. Vmware snapshots (note, these are initiated by the n-series/netapp storage) fail with errors such as:
2009-11-20 00:15:25,830 WARN - VMware Task "CreateSnapshot_Task" for
entity "server1.domain.COM" failed with the following error: The
operation is not allowed in the current state.
2009-11-20 00:15:25,830
ERROR - VM "server1.domain.COM" will not be backed up since vmware snapshot create operation failed.
and
The operation is not allowed in the current state, under the Tasks and Events tab.
I'm just noting what we are seeing/doing. After we contact IBM support, we are just going to try to Vmotion the VMs off the weird blade and reboot it.
Our system is composed of IBM n-series storage (IBM branded NetApp), an IBM H chassis (BladeCenter-H), several blades HS22 (Type 7870), and Cisco ethernet switches.We use NFS for the storage. We still have a very very light load on this whole system because we keep seeing random bugs like this.
Are these just typical vCenter type bugs not to worry about? Reboot and you are fine type stuff, sort of like things you typically see in the windows world? Or something more sinister is lurking?
