NetApp OSSV Notes

So, Open System Snap Vault is NetApp's answer to backing up everything that you can't backup with SMVI (VMware VMs) or Snap Manager for Exchange/SQL Server/SharePoint.  Here's a table a notes about the different backup methods I'm finding out about from NetApp.  Quick overview from NetApp here.  Note, FAQ says that Linux OS backup is not supported.

It's software you install on a physical or virtual machine that does NetApp block level backup of any data (NetApp or otherwise) to a NetApp SnapVault node.

I thought it simply used NDMP protocol, but it seems it sends the data with QSM (Qtree Snap Mirror) and seems to setup the relationship or do the backup management with NDMP:


NDMP port (default value is 10000)
FILESERVER port-10555.
QSMSERVER port-10566.

Components:

• NetApp Host Agent (install this first)
• Host Agent Plugin (comes with Host Agent)
• NetApp OSSV

Host Agent

Windows: agentsetup-2-7-win32.exe

Linux: ./agentsetup-2-7-linux.bin

Unpacking files needed for the installation ...

Beginning the installation ...

Starting agent.

        You may now point your browser to

            http://127.0.0.1:4092/welcome

        to configure the agent software.

This is NTAPagent service (which runs /opt/NTAPagent/ntap_agent) on linux 

or ntap_agent.exe on Windoze

Like this diagram shows, set a password for the "admin" login on the Host Agen application on your backup client.  This is unhelpfully referred to as the Mgt API Password here.










Install Host Agent Plugin

Windows runs this automatically: 

c:\Program Files\netapp\snapvault\manageability\InstallHostAgentPlugins.exe

But for Linux you need to run:

./ossv/manageability/InstallHostAgentPlugins.sh

before you can get DFM to connect to OSSV on your backup client.

OSSV

License OSSV on your SnapVault servers with these generic licenses available from NetApp Now website.

Install OSSV on your backup client

uses port 10000 for NDMP backup between client and NetApp

configure NDMP user/password and SnapVault filers (names separated by commas)

Runs on most OS'es (Windows, Linux, Solaris, etc.) but you can only create luns from Windows OSSV.

Seems to be different versions of OSSV for Windows 2003 and Windows 2008, but same for Host Agent. 

Gotcha: SnapVault relationship wouldn't create on my Linux backup client until:
1.  stop service on linux backup client
service snapvault stop
2. backup and edit /usr/snapvault/config/snapvault.cfg:

changing:

[QSM:Check Access List]
Type= CheckBox
value= TRUE

to:


[QSM:Check Access List]
Type= CheckBox
value= FALSE



3.  And starting service again.  
service snapvault start
This was much easier than getting the syntax for the svsetstanza command.  (^;

NetApp Host Agent is recommended for managing OSSV.
OSSV could not detect NetApp Host Agent on this system.
If you install this software later, you can install OSSV plugins using

Bits & Bobs:

LREP: allows out-of-band data transfers to keep load off normal channel, can be used to transfer data to portable disk for physical transfer to another location.

Enable OSSV compression on SnapVault if required.

DFM setup:

Go to OSSV tab in NetApp Mgt Console on DFM server

Click "Add" 

have NDMP username and password ready

password needs entering as it is shown from the command on the SnapVault server from the ndmpd command:

ndmpd password backup

where NDMP user is called "backup"

CLI snapvault check:
