# Populate only the serial number for HPE BladeSystem

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 1.35.0 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 **All** > **MID Server** > **Properties**.

2.  In the **Name** column, search for `sn_itom_pattern.clear_hpe_serial_numbers`.

3.  Select the **sn\_itom\_pattern.clear\_hpe\_serial\_numbers** MID Server property.

4.  In the **Value** field, enter `true`.

    To revert to the default behavior, set the value to `false`.

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.
