Open the required ports between all components, including the NAS. The
PowerProtect Data Manager Appliance Security Configuration Guide provides more information and instructions.
For example, Windows file servers require an outbound rule to allow traffic on ports 139 and 445. Modify the firewall to open these ports.
NAS protection engines require time synchronization with
PowerProtect Data Manager Appliance for deployment and operation. Configure an NTP server. In the time configuration options for each ESXi server, enable the NTP client and ensure that the NTP service is running.
Ensure that NFS service is enabled on
PowerScale cluster for protection of CIFS shares. If the NFS service is not enabled, the backup of CIFS shares that are discovered from a
PowerScale appliance fails.
Appliance protection
The following prerequisites apply for
PowerScale appliances:
The
PowerScale OneFS Web Administration Guide and
PowerScale OneFS CLI Administration Guide provide more information and instructions, where not otherwise indicated here.
Create a NAS protection user in the System access zone with the
BackupAdmin role.
The NAS protection user needs read/write Windows ACL NTFS and share permissions.
Supply the NAS protection user credentials as the management credentials when you add the NAS appliance, when you add CIFS shares to a protection policy, and when you set asset level credentials.
Some required paths are not shared by default. Add the
NAS protection engine and
PowerProtect Data Manager Appliance by hostname, FQDN, or IP address as clients, root clients, and read/write clients to the NFS export.
For NFS shares, add clients to the exports for other shares, as required.
Files with restricted permissions provides more information.
For NFS shares, change the global settings to enable NFS export services. Enable NFSv3 or NFSv4, as required.
If you configure NAS appliance protection with multiple DNS servers, ensure that you enable the DNS forward or the DNS server entries are available on
PowerScale SmartConnect.
For SMB shares, configure the following settings in the
PowerScale UI SMB server settings area:
A trial license is provided with the
PowerProtect Data Manager Appliance software. Contact
Customer Support for assistance with a permanent
PowerProtect Data Manager Appliance license.
If you specify a hostname or fully qualified domain name (FQDN) with an underscore (_), the communication happens by IP address, as provided during registration when signing occurs during certificate exchange between
PowerProtect Data Manager Appliance and NAS asset sources.
Before you add a
PowerScale appliance version 9.3 or earlier , enable basic authentication through the appliance console. To enable run the following command in the
PowerScale console.
isi_gconfig -t web-config auth_basic=true
