Thanks all, I didn't think that was possible but had to verify. I checked every config option when checking the reports output and SRM gives you a lot of options, just SerNo is not one of them. Appreciate it!
So we have this project where we want to clean up our relationship between SRM and ServiceNow and we need to be able to correlate each Isilon node with a serial number and validate that info. Basically we want to see if SRM and ServiceNow are reporting the same data.  I've poked around SRM and I can get a lot of data but I simply cannot find where I can get a complete list of the nodes in the cluster and the associated Serial Numbers. Anyone done something similar before? Or does this require a license?
SRM reports, any way to drill down for Serial Numbers on Isilon
