Question
A customer has two IP Replicated VNX systems: VNXA is the Primary system; VNXB is the DR system. VNXA is configured with VDMs containing CIFS servers, has secmap cache disabled, and runs a primary Usermapper. VNXB is configured as a DR target system and runs a secondary Usermapper. During failover testing, VNXA is failed over and shut down to simulate a site outage. The small number of Linux users that access the CIFS data via NFS find that they no longer have the same permissions as when accessing from the primary site. Additionally, the UID ownership of many files has changed. What could be the cause of the change in permissions?
Options
- ALDAP requires re-configuration and resynchronization when failing over sites.
- BThe ID mappings of the Primary and secondary Usermapper do not match.
- CThe DR site must be promoted to become a primary Usermapper on failover
- DDNS has not yet re-synchronized to reflect the new CIFS server addresses.
