One note about discovery of ESXi 5.0 servers with Dell OpenManage EssentialsPosted: October 31, 2012
Even though we’re using the Dell Management Plug-in for vCenter, we use Dell’s OpenManage Essentials (OME) for physical boxes. I want to be able to view ESXi server info from OME, as well, though. After initial configuration, my ESXi servers were showing up as “Unknown” even though they were correctly categorized as “VMware ESX Servers” in OME. This irritated me because I had finally configured my physical servers to show nice green check marks to show all was well but I couldn’t get my ESXi boxes to play nicely. As the ESXi boxes sat as unknown, they also did not have detailed hardware inventories available.
Now, I’ve been unimpressed by Dell’s hardware management platform so far even though the idea of it promises to be a big time saver and monitoring tool. When I have it configured, not only will I get SNMP hardware monitoring, but I should be able to upgrade firmwares and BIOSs remotely. Mostly, I’ve been dissatisfied by the lack of clear and organized configuration steps for, what I consider to be, a pretty standard data center: mostly virtualized with a few physical servers scattered about. As a note, I haven’t yet configured Dell’s management and monitoring stack to keep track of our remote office hardware, but it’s on the list of things to do.
Real quick, let me show you what I’ve come up with.
The OMSA VIB can then be queried, and thus the server inventoried, using WS-MAN, or Web Services Management. When working within OME, right click on your discovery range and select WS-Man Credentials. You’ll input your ESXi root credentials here. The key options are highlighted in the screenshot below – the most important being that you increase the timeout value to 10 seconds – up from the default of 4 seconds. ESXi seems to take a while to respond to these queries so you need to increase it. As of summer 2012, Dell didn’t have a ship date for an update that set this timeout to 10 seconds as a default.
After making this change, my ESXi servers show up with nice little green check marks and a full hardware inventory.
Before I go, I should mention that there was a lot more configuration to be done that led me to this point. I may just make documentation of my own – I’ve been taking Microsoft OneNote screenshots and notes along the way so I just might do that and share it with y’all. Let me know if this was helpful.
