Adding an asset on a remote network

I saw an interesting question about discovering assets:

"I'm trying to discover a new chassis. I have three Proxy Controllers and all of them can ping the chassis, but only one has the firewall access to communicate with it. None of the Proxy Controllers has a direct connection to the network with the chassis, so that network isn't in the network list. How do I get the discovery job to route correctly?"

There is a solution in the discovery profile here. The discovery profile has a field for the target host or IP address, and a dropdown for the network. When you put the profile together, you supply the asset's IP address, and then select a network that has a route to the network with the chassis on it. Run that and you'll be able to discover the asset.

How To: Discover an Oracle SPARC T5 Server

When you're deploying new hardware, it's helpful to have as specific a plan as possible. For instance, it's good to know how to run a discovery in Ops Center, but if you have a guide that specifically explains how to discover the type of hardware that you're installing, that makes your job even simpler.

With that in mind, we put together a How-To that explains how to discover new Oracle SPARC T5 servers. It walks you through creating IPMI and SSH credentials, creating a discovery profile, and running it to discover the new system or systems. It also gives you pointers to the asset management and hardware management chapters in the feature guide, which provide a broader range of information about discovering and managing hardware.

Discovery question

I got a question about discovering operating systems:

"My operating systems are configured not to allow root SSH access. How can I discover these OSes with Ops Center?"

When you're creating a discovery profile, you provide credentials for each protocol being used to access the asset. So, for an Oracle Solaris OS, you provide SSH credentials. If root SSH access is allowed by the system, you can provide root credentials.

However, if root SSH access is not allowed, you can provide one username and password to use for logging in, and then the root credentials to use for managing the asset.

Here's what it looks like in the UI:

The first set is used to log in, and the second set is used to perform tasks that require root access, such as installing or uninstalling Agent Controllers.

Discovering Assets on Multiple Subnets

I saw this question recently, about making discovery work:

"I am attempting to discover a group of ILOMs which seem to be on a different subnet than their hosts. When I try to discover the ILOMs, Ops Center can't find them. Is it a requirement that the ILOM and its host should be on the same subnet?"

The short answer is no, related assets don't have to be on the same subnet for you to discover them. The correlation between related assets doesn't depend on them being on the same subnet.

What's likely going on, if you're running into similar issues, is that the subnet where you're trying to discover systems needs to be associated with a Proxy Controller that can reach it. You can go here to see how to associate a network with a Proxy Controller. Once the network is associated with a Proxy Controller, you should be able to discover and manage assets on it.

Discovery methods

In Ops Center, asset discovery is a process in which the software determines what assets exist in your environment. You can't monitor an asset, or do anything to it through Ops Center, until it's discovered. I've seen a couple of questions about how to discover various types of asset, so I thought I'd explain the discovery methods and what they each do.

Find Assets - This discovery method searches for service tags on all known networks. Service tags are small files on some hardware and operating systems that provide basic identification info. Once a service tag has been found, you provide credentials to manage the asset. This method can discover assets quickly, but only if the target assets have service tags.

Add Assets with discovery profile - This method lets you specify targets by providing IP addresses, IP ranges, or hostnames, as well as the credentials needed to connect to and manage these assets. You can create discovery profiles for any type of asset.

Declare asset - This method lets you specify the details of a server, with or without a configured service processor. You can then use Ops Center to install a new operating system or configure the SP. This method works well for new hardware.

These methods are all discussed in more detail in the Asset Management chapter of the Feature Reference guide.
