Non-existent VLUN

Problem

This error occurs if the 3PAR host exists with the correct host name that the OpenStack Block Storage drivers expect but the volume was created in a different domain.

HTTPNotFound: Not found (HTTP 404) NON_EXISTENT_VLUN - VLUN 'osv-DqT7CE3mSrWi4gZJmHAP-Q' was not found.

Solution

The hpe3par_domain configuration items either need to be updated to use the domain the 3PAR host currently resides in, or the 3PAR host needs to be moved to the domain that the volume was created in.
