TDP for VE file level restore for Linux

Using TDP for VE, you can mount a Virtual Server filesystems, or disks directly on a Data Mover Server, and also map shares (SMB for Windows and NFS for Linux). This operation is done using the Web interface from TDP for VE, also available as plugin the the Vsphere Web interface: https://datamover:9081/TsmVMwareUI

I've a Windows 2008R2 data mover installed with TDP for VE
Windows Data Mover is also configured as Mount Point Server for Windows servers (for file level restore).

To be able to use file level restore on Linux servers, I've installed CentOS 7 x64.

Requisites:

linux package lsscsi
linux package iscsiadm
TSM client for linux 7.1.1 (same version as running on DataMover)

Configure the Linux Mount Point Server

Use the same TSM ba client package than on main proxy !

Configure the TSM client acceptor, and also start the required services iscsi and nfs-server

After mount operation on the DataMover node

The mount operation is done directly from Web Interface https://datamover:9081/TsmVMwareUI, select Restore, Restore Points, and select your linux VM to mount. You have to choose in the mount wizard, the Windows primary Mount Proxy Node pair.
