System Requirements for OSDP C-Mode

Verify that the following system requirements are ready for the OSDP C-Mode feature:

Note: One single installation of OSDP C-Mode is supported.

• The NFS (Network File System) server must be running on the vServer that replicates the data.

• The vServer must have at least one logical interface (LIF) that has the data-protocol set to NFS.

• On the cluster associated to the storage virtual machine, disable the NFS mount root only and NFS root only by running the command nfs modify.

  For example, on the cluster, type the following command that disables the NFS mount root only and the NFS root only on a storage virtual machine called nfs_vs:

  nfs modify -mount-rootonly disabled -nfs-rootonly disabled -vserver nfs_vs
  

• On the vServer, enable the iSCSI interface for LUN mounts and keep the iSCSI ports accessible for the destination vServer. For indexing purposes, the client or the proxy computer mounts the LUN from this vServer.

• NFS, HTTP, and HTTPS ports for the destination vServer, that is, the vServer to which OSDP C-Mode data is replicated to must be accessible via any firewall configuration.

• Behind a firewall, the NFS service uses a port mapper port, a NFS service port, and a mountd service port. By default, the ports have the following numbers:

  • 111, for the port mapper service,

  • 2049, for the NFS service,

  • 635, for the mountd service.

  If the mountd service port number is different than 635, then OSDP jobs might fail.To verify if the port numbers meet the default list, run the following command on UNIX systems or Cygwin software:

  rpcinfo –p <NFS Server IP \ File Server LIF with NFS>
  

  If the port numbers do not match the list, then contact the file server administrator or the firewall administrator to allow the port numbers for OSDP.

• On the OSDP client computer, you must give read-only permission for the NFS protocol to access the default policy or the policy associated with ‘/'.

• The provisioned volume must use the export policy which gives the OSDP client computer read-only and read/write permissions for the UNIX protocol.

• If you use an agent the indexes and catalogs during the backup operation, for example, a file system agent, then before running the backup operation, make sure that the source computer and the proxy computer are connected to the SVM using SAN connectivity (iSCSI or fibre channel).
