Whilst attemping to install the Dell ESXi Agent and upgrade the ESXi revision on a new VMware host, I hit the following issue. Dell Agent - Error encountered: Description - I/O Error (17) on file /var/tmp: [Errno 17] File exists: '/var/tmp' Message - Unable to create, write or read a file as expected.I/O Error (17) on file /var/tmp: [Errno 17] File exists: '/var/tmp' ESXi upgrade with Update Manager - The host returns esxupdate error codes: 10.
In ESXi 4.0 the Advanced Software Setting UserVars.CIMOEMProvidersEnabled is used to enable an agent such as the Dell OpenManage offline bundle for ESXi which provides hardware management for Dell PowerEdge servers. This is supplied as a vSphere Installation Bundle (VIB) and Alan Renouf has a great post on his blog on how to install a VIB like this one via PowerCLI. Whilst testing out getting the same Dell Agent installed into ESXi 4.
