NAS device validations
When adding or editing a NAS device, the Device Validation window is displayed. For more information, see Add a NAS device and Manage your NAS device.
The Device Validation window contains basic validations and vendor-specific validations.
Vendor-specific validations are supported for Dell EMC Isilon.
The following are the basic validations.
|Share mount successful||Validate the share mount. Only applicable for SMB.|
|Network Connection||Connection to the NAS device.|
Isilon Cloudpool's Hierarchical Storage Management (HSM) provides the ability to convert regular files into small size stub files also known as SmartLink files. This helps reduce the TCO on the primary NAS filer, as the original regular file is moved to cold storage or a cheaper secondary storage tier.
For a user, this file appears to be on disk and is available for use, but is actually stored on different storage. If stub files are not identified during backup, they are treated as regular files and get backed up. This adds additional cost for the customer, whenever Druva retrieves data from the Isilon secondary tier to the primary tier. For more information, see Dell EMC Isilon documentation.
If the following validations are successful, then the stub files are identified and skipped. Otherwise, they are processed as regular files.
|Minimum NAS proxy version is 5.0.2||Agent on the proxy with the minimum supported version.|
|Connection to OneFS via the URL and port succeeded||Network connection to OneFS with the given endpoint details.|
Credentials are valid
Same credentials must be used for both share mounting and OneFS.
Supported OneFS version
Version 8.2.2 and above.
Credentials have all the required privileges
The system zone user must have the following privileges:
While using a custom zone, create a new user in the custom zone with the same name which exists in the system zone, and provide the following read-only privileges:
|Active SnapshotIQ licence detected||Users must have the active SnapshotIQ license.|
|Successfully able to access snapshot||Users must have access to the snapshot created on the Isilon device.|
For a Full scan backup, Isilon snapshots created by Druva will be deleted automatically after 180 days. Otherwise, they will be deleted after 31 days. For this to happen, you must enable the autodelete of snapshots from the:
- Isilon UI (SnapshotIQ tab)
- command-line interface using the following command:
isi snapshot settings modify --autodelete enable
Isilon backup validations
Dell EMC Isilon supports the following permissions related to snapshot accessibility for both SMB and NFS:
- Root directory accessible
- Sub-directories accessible
At least one of these permissions must be enabled.
If both the permissions are enabled, then the default permission used is Sub-directories accessible.
Note: The Root directory accessible permission will only work if /ifs (ifs share) is accessible to the user.
