How to increase the persistent disk of the DB VM

Hi,

We have configured the persistent disk for the DB as below in our deployment manifest but when i increase it to higher value I m getting the below error.

  • name: db

instances: 1

azs: [AZ1]

networks:

  • name: PCF-CC-XX

static_ips:
- XX
stemcell: xenial

vm_type: large.disk

persistent_disk_type: 153600

Error:

                L Error: Instance group 'db' references an unknown disk type '253600'

Task 765 | 11:21:08 | Error: Instance group ‘db’ references an unknown disk type ‘253600’

Task 765 Started Wed Mar 18 11:21:08 UTC 2020
Task 765 Finished Wed Mar 18 11:21:08 UTC 2020
Task 765 Duration 00:00:00
Task 765 error

Updating deployment:
Expected task ‘765’ to succeed but state is ‘error’

Ignore this issue. I gave the wrong properties that are not in cloud_config
