Are vfilers supported with SnapProtect?

Hi there,

We are experiencing some problems when using SnapProtect with vfilers.

We are trying to backup a NFS ESX Datastore which is served through a vfiler. SnapProtect creates the required snapshots on primary storage fine. On a second step, SnapProtect talks to DFM to archive that snapshot to secondary storage, but the operation fails, probably because SnapProtect treats de vfiler as a physical FAS although there are some operations that cannot be performed against the vfiler.

Do we have any official statement about what is supported/unsupported with SnapProtect and vfilers?



Are vfilers supported with SnapProtect?

SnapProtect supports vFilers as sources and pFilers as destinations for replication. SnapProtect does not support the configuration of vFilers as replication targets.

Re: Are vfilers supported with SnapProtect?

Note that SnapVault and SnapDiff – both components used by SnapProtect – currently have limited support for vFilers. At present, SnapDiff API does not support vFilers; SnapVault does not support vFiler as a backup destination.

Both limitations will be addressed in RR.1.

Are vfilers supported with SnapProtect?

Thanks for your anwsers.

I will try to be more specific.

I was talking about using a vfiler as the snapvault source. According to the documentation it's supported and should be working... but the truth is that we are finding problems to make it work. Has anyone tested this configuration?, are there any special considerations when dealing with vfilers?... we just added them to SnapProtect as any other physical array... 

Here's a description of the problem we are experiencing:

When getting to do the secondary snapshot (snapvault), SnapProtect talks to the DFM and according to the DFM logs, it lists all the hosts using API host-list-info-iter-start, this list includes physical filers and virtual filers (vfilers). For each of these hosts SP tries to get a list of interfaces using the API netif-ip-interface-list-info, which uses a snmpwalk. The problem is that vfilers don't implement SNMP so the call to that API fails when trying to run the query against a vfiler. SP outputs an error similar to "DFM error: SNMP walk failed" and the secondary snap job fails.

That's why I am asking if we need to make any special configuration for vfilers or we can treat them just as standard arrays...

Is this an issue of SnapProtect not making the proper API calls to the DFM when dealing with vfilers as primary storage?

Thanks for your help!

Can you describe what systems you have defined in Array Management (in SnapProtect) as well as in Host Storage Systems in Protection Manager?  I want to know where you have vfilers listed vs the physical host.

Are vfilers supported with SnapProtect?


It seems I'm not authorized to upload any screenshots to the communities so I will try to explain it with omly text:

I have used ComCell Console > Control Panel > Array Management to configure physical systems, vfilers and DFM in SnapProtect:

  • For Physical System and vfiler I used "File Server" type and marked the checkbox "Primary"
  • For DFM I used "Data Fabric Manager" type

So in the Array Management window I have IP address and login information for DFM, Physical System and Vfiler.

The following is the output from a "dfm hosts list". The one in bold and underlined is the vfiler that I'm trying to backup.
