Verify that you have set the sn_itom_pattern.clear_hpe_serial_numbers
MID Server property to true and run HPE BladeSystem discovery. For more information, see [Populate only the serial number for HPE BladeSystem](https://www.servicenow.com/docs/lFBbH0aBBJ5EubFQr38YjA "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).").

Role required: admin

## About this task

After setting the sn_itom_pattern.clear_hpe_serial_numbers
MID Server property to true and running HPE BladeSystem discovery, new CI records are created with only the serial number value. You can run the Clear HPE Blade Serial Numbers
scheduled script to delete existing records with UUID-formatted serial numbers. The script affects the HPE BladeSystem Enclosure \[cmdb_ci_hpe_bladesystem_enclosure\], HPE BladeSystem Blade \[cmdb_ci_hpe_bladesystem_blade\], and
Serial Number \[cmdb_serial_number\] tables.

2. In the Name column, search for <kbd class="ph userinput">Clear HPE Blade Serial Numbers</kbd>.
3. Select Clear HPE Blade Serial Numbers.
