CTA disaster recovery and stub pointing

Hello everyone,

We have the following scenario at a customer site:

HQ-VNX

HQ-CTA

HQ-CTAHA

HQ-Centera

DR-VNX

DR-CTA

DR-CTAHA

DR-Centera,

There is a file system replication from HQ-VNX to DR-VNX, and object replication from HQ-Centera to DR-Centera, as well as regular backups being taken for HQ-CTA and replicated to DR and accessible by DR-CTA.

HQ-CTA is configured properly with HQ-VNX and HQ-Centera, archiving is running fine (Source=VNX, Target=Centera), HQ callback is fine as well.

1- What's the best practice to configure the disaster recover for DR-CTA ? can I test callback from DR if I failed over a VNX filesystem to DR ? Note: I couldn't find a document to explain the DR configuration for CTA, if there is, please attach it.

2- How can I read the contents of the stub file and it's meta data ? I want to know where it points to for further troubleshooting.

Please advise
