Discovering and adding PowerScale configured with SmartConnect and multiple access zones

For NAS, PowerProtect Data Manager supports multiple access zone and SmartConnect zone names with PowerScale. These zone name allows you to protect PowerScale NAS assets across all zones and use the SmartConnect zone names for backup and recovery.

SmartConnect acts as a DNS delegation server to return IP addresses for SmartConnect zones, generally for load-balancing connections to the PowerScale cluster. See the PowerScale OneFS Web Administration Guide for more information about SmartConnect and its configuration detail.

From 19.12, PowerProtect Data Manager discovers and adds shares or exports from all the access zones in the PowerScale appliance.

PowerScale appliance added as asset source

You can add a PowerScale appliance with the management node IP. See Add a NAS appliance for more information. In PowerProtect Data Manager 19.11 and earlier, only system zone shares were discovered. In PowerProtect Data Manager 19.12 or later, shares and exports from both system and nonsystem access zones are discovered and added to the Assets page.
NOTE:
  • You can identify whether the zone is a system or a nonsystem zone from the Zone/Server Name/IP column on the NAS tab of the Infrastructure > Assets page.
  • After making any configuration changes in PowerScale or NAS appliances, run a discovery in PowerProtect Data Manager to view the recent status of assets.
  • Along with these asset source entries, entries added in previous releases are also listed on the Asset Source page. If there are duplicate entries, you can delete the duplicates.

PowerScale shares added as asset sources

PowerScale shares can be added as generic asset sources in PowerProtect Data Manager. See Add a NAS share for more information. You can add generic shares with the management node IP (system zone shares or exports), zone IP, or SmartConnect zone name. In PowerProtect Data Manager 19.12 or later, existing shares that are added with the management node IP remain generic PowerScale shares and are not added as assets. However, shares that are added with the zone IP or SmartConnect zone name are added as assets.
NOTE:
  • You can view zone names of discovered NAS assets under the Zone/Server Name/IP column on the NAS tab of the Infrastructure > Assets page.
  • You can add shares with a SmartConnect zone name, regardless of their NFS or CIFS type.
  • If you want to add a system zone share as a generic asset source from PowerScale, add those with the management node IP to prevent the mount operation for that share from failing.
  • Access zone names greater than 255 bytes cannot be protected by PowerProtect Data Manager DNAS due to PowerScale limitations.
