Why is the serial number of a blade appended with uuid in the pattern of UCS-HD (Step 15)?
$cmdb_ci_ucs_blade.blade_serial_number + "::" + $cmdb_ci_ucs_blade.uuid
This is as designed and has been implemented to ensure maintaining unique identifiers for the CIs and avoiding duplicates.
If you need to use the partial values you can use blade_serial_number and uuid individually.
This could potentially cause issues with Data Imports and Asset Management. In case of further issues please open a support case.
