Requires Access To:
VMHA audit on Cisco UCS ESXi hardware returns the Serial number of the chassis, not the blade
Cisco devices have multiple AssetTag identifiers in the idetifier data exposed through the VMWare API
Solution / Workaround:
A patch was developed that is compatible with 2017.2.x and 2017.3.x versions of ISM (it will be baked into 2018.1.x and later) which allows the VMHA audit to be configured to return the First, Last, or All (concatenated) Asset Tags found in the audit. For Cisco UCS devices with this problem, using the "ALL" setting is appropriate.
Please download the patch and follow the instructions in the zip file to apply it to the Gateway machine.
