Calling System Center Orchestrator Runbooks from vRealize Orchestrator

Sometimes you end up having to put in place an implementation that’s pretty crazy to get something (non-production) over the line. This was the case recently where I used vRealize Orchestrator (vRO) to call System Center Orchestrator (SCORCH) Runbooks. That is, using Orchestrator to call Orchestrator…

yo dawg...

A lot of the credit for figuring out how to do this goes to Laurie Rhodes and their blog post about calling SCORCH runbooks via REST using Powershell. It was my starting point for this piece of work and I was able to adapt the core pieces of this for my scenario.

vRO Configuration

Assuming there’s existing SCORCH and vRO instances, the first task is to add the SCORCH server as a REST host in vRO. This can be achieved by running the “Add a REST Host” workflow that comes with vRO. The “Orchestrator Web Service” runs on port 81, so that will affect the settings for the host.

vRA 8 – GetDiskInfo: ERROR: Partition name buffer too small

After spending a lot of time looking at the web interface for vRealize Automation 8 (vRA 8), I decided to look under the hook a bit. One of the first things I looked at was the logs. It seems one of the primary logs that vRA 8 uses is /var/log/vmware-vmsvc.log Upon viewing this log, I was greeted with the following spam:

[2019-12-05T11:47:54.126Z] [ warning] [guestinfo] GetDiskInfo: ERROR: Partition name buffer too small
[2019-12-05T11:47:54.126Z] [ warning] [guestinfo] Failed to get disk info.

[2019-12-05T11:48:54.128Z] [ warning] [guestinfo] Failed to get disk info.

As shown by the timestamps, this error will repeat every 30 seconds, resulting in this log being totally flooded with this error. I also confirmed this error was happening in another instance than my own. Upon googling the message, I found a Github issue entry that referenced this and how it can be caused by the very long paths with Kubernetes. vRA 8 uses Kubernetes heavily. The code fix that resolved this issue appears to have been folded into the v11.0.1 release of the open-vm-tools. When checking the version on the vRA 8 appliance, we can see the following:

That explains that

When checking the package info via yum, the versions available range from 10.2.0 to 10.3.10 from the repositories that vRA is configured to use. So it appears updating isn’t an option at this time.
