I received the following email alert and found one of the servers used in LabManager disabled. Any ideas what I should be looking for or doing to correct this. The Managed Server 'server name' attached to VMware Lab Manager at x.x.x.x has been disabled as COW disk size of one of the deployed VMs on this Managed Server could not be updated.
I received this error again now on a different host.
Last week on Tuesday the LabManager environment was upgraded to 2.5.3 and the hosts were upgraded to ESX 3.5 Update 1. Previously the hosts were on 3.0.2 and LabManager was version 2.5.
When this error occurs and I go into the LM console and click on Servers the host that I received the warning on is set to disallow deployments. I can go back in and set it to allow deployments (enable). I am just not sure why this is occurring. I have never seen this error before and have not found any information in the forums or anywhere else on this.
Any help is appreciated.
Hi, Aaron-- In 2.5.3, we collect new information about the disks in the trees to help manage the disk chain. When we can't get the information for disks on a machine on a given host, we prevent deployments onto that host until we can; that is what you are seeing. The issue should go away once all the hosts are enabled after upgrade.
As Steve mentioned, LM is trying get disk information of all the deployed VMs and its failing for some VMs.
Can you try the following:
Make sure that the agent is upgraded correctly on all the hosts i.e. 2.5.3.666 agent is installed. You can verify this by going to the servers page and checking the Lab Manager Agent Version
Make sure that the managed server is reachable
Undeploying / Redeploying the VM should resolve the issue for that particular VM
