Hi folks,
Short description of my environment: Data ONTAP 8.3.1, two clusters: clus1, clus2 (different physical locations)
In my environment I've got couple SVMs serving CIFS-only or CIFS/NFS data. Each primary_SVM (clus1) has it's secondary_SVM created on clus2 (different location) to which all volumes are replicating (via snapmirror). No customer access to secondary_SVMs. Both SVM subtypes are default. This configuration was created while those clusters were on ONTAP 8.2 (No "SVM_DR" available at that time). All volumes are being replicated, however secondary_SVM has no replication of CIFS shares or NFS export-policies. Please correct me if I'm wrong, but I understand such configuration as volume-level disaster recovery setup.
Lately a new SVM has been created, and since ONTAP version (8.3.1) gives us the possibility to create SVM DR relationship, the new_SVM (SVM subtype: default) in clus1 has it's new_SVM_DR (SVM subtype:dp-destination) on clus2. In this configuration all CIFS share information is also replicated to my DR site (clus2).
Now time for main main questions:
1. Is there any way I can transition/modify my old_secondary_SVMs (subtype: default) to DR_secondary_SVMs (subtype:dp-destination)? I would like to replicate CIFS shares information, and hopefully export policies for volumes and qtrees. What I would love is to avoid a need for data baseline transfers.
If there only way is a need to destory SVM_secondary and create a new one as subtype:dp-destination, but I can still keep the volumes on clus2 - I'll be able to resync volumes snapmirror without going through baseline again - that would be great!
2. My DR plan assumes: SVM_DR has a seperate CIFS server with seperate objet / different name joined to the same domain. During DR we would only create a DNS alias SVM_name (-alias->) SVM_DR_name. In such configuration we should set Identity-preserve to false - correct? How can I secure my NFS shares / export-policy information to DR site then? According to what I read, export-policy is only replicated if identity-preserve=true is set, but that would affect my CIFS config during DR.
Thanks in advance.
