Applies to

  • Active IQ Unified Manager (AIQUM)
  • OnCommand Unified Manager (OCUM)
  • OnCommand Workflow Automation (WFA)

Answer

  1. Unified Manager (UM) must be connected to WFA server from the UM Web UI
  2. A SnapMirror license is required for SnapMirror protection
  3. A SnapVault license is required for backup SnapVault protection
  4. The following ports need to be open for NDMP communication
Port Endpoints

10000

  • UM server <-> source cluster management LIF
  • UM server <-> destination cluster management LIF
11104, 11105, 18600 - 18699 Intercluster (IC) LIFs between clusters
  • Note: You can reduce the port range by using the option ndmpd.data_port_range for IC LIFs

vserver services ndmp modify -vserver * -data-port-range 18600-18699

  1. Vserver scoped needs to be enabled with the NDMP allowed protocols verification
  2. Create a Vserver NDMP password
  3. Cluster and vserver peers must be intact and running 
  4. Both source and destination clusters must be added to the UM server and have successful inventory without any errors
  5. Users/Permissions involved to setup the protection relationship are:
    • UM: admin with OnCommand Administrator
    • Cluster:  Local Cluster Admin Account
      • A remote(domain,ldap,saml) user will not work due to not being able to generate an ndmp password for the account on the cluster
  6. Collect the following information before creating 'SnapMirror' or 'SnapVault' relationships on a source volume:
    • Source volume type should be read-write
    • Destination cluster name
    • Destination Vserver name
    • Destination aggregate
