# Populate only the serial number for HPE BladeSystem discovery

# Populate only the serial number for HPE BladeSystem {#ariaid-title1}

Release version: Australia  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
You can exclude the universally unique identifier (UUID) from the Serial number field for discovered HPE BladeSystem Enclosure and HPE BladeSystem Blade configuration items (CIs).

## Before you begin

Verify that you have at least version 1.35.1 of Discovery and Service Mapping Patterns.

Role required: discovery_admin

## About this task

By default, Discovery populates the Serial number field for HPE BladeSystem Enclosure \[cmdb_ci_hpe_bladesystem_enclosure\] and HPE BladeSystem Blade \[cmdb_ci_hpe_bladesystem_blade\] CIs in the
format serial_number::UUID. The sn_itom_pattern.clear_hpe_serial_numbers
MID Server property controls this behavior. When set to true, Discovery populates the field with only the serial number value. The default value is false.

## Procedure

1. Navigate to AllMID ServerProperties.
2. In the Name column, search for <kbd class="ph userinput">sn_itom_pattern.clear_hpe_serial_numbers</kbd>.
3. Select the sn_itom_pattern.clear_hpe_serial_numbers MID Server property.
4. In the Value field, enter <kbd class="ph userinput">true</kbd>.  
   To revert to the default behavior, set the value to <kbd class="ph userinput">false</kbd>.
5. Select Update.

## What to do next

Run Discovery again to apply the change.

To delete existing CI records with the serial_number::UUID serial number format, run the Clear HPE Blade Serial Numbers scheduled job. For more information, see [Clear UUID serial numbers from existing HPE BladeSystem CIs](https://www.servicenow.com/docs/OxKF54FdUWf4kMMD6oeGLA "Delete records with UUID-formatted serial numbers from HPE BladeSystem discovery tables.").
