This issue has been solved. See solution.

Thank you for response,now I got basic understanding on AIR

I have another question,these days I am hearing much about OST/OST Device,What is this OST? 

With my basic knowledge I understood that it is some thing related to storage technology,in our organization We are using 3 types of storage

1)San based

2)HP MDS6000 enclosures

3)Pure disk appliance,they say that they are using this PD apliance as OST device for other media server

Are all this 3 types are called OST?

What is criteria to call something OST?

Symantec OpenStorage allows storage partners to deliver backup and recovery solutions with tighter integration with NetBackup. When Partners become members of the Symantec Technology Enabled Program (STEP), they gain access to the OpenStorage API. Partners write code for a plug-in that can be installed on the media server platform(s) of their choice (e.g., Windows, Solaris, HP-UX, IBM AIX, and Linux).
OpenStorage API separates backup business logic from storage device implementation
OpenStorage supports any connectivity, any protocol (FC, TCP/IP, combination), and any file system format
Collaborate with Symantec engineers to expose the most important features for customers

n recent years many intelligent storage devices targeted at backup and recovery have been introduced to the market. Examples include Data Domain, the Quantum DXI Series and Falconstor. These devices include advanced capabilities such as deduplication, replication, creating copies and writing directly to tape. The challenge has been that there was no way to coordinate these activities with the backup and recovery software. The appliance could make a copy to tape but the backup software was unaware of it. This meant that the backup catalog was incomplete. In addition the backup software had no way to manage the device or tell it to perform certain functions such as making a copy. Symantec developed OST to address these issues.
 
OST stands for OpenStorage Technology and at a high level it is an API that allows NetBackup Media servers to take advantage of intelligent disk devices as well as cloud storage solutions. Storage vendors that participate in Symantecs STEP (Symantec Technology Enabled Program) are given access to the OST Software Developers Kit allowing them to create plug-ins that more tightly integrate their devices with NetBackup. The OST plug-ins are provided either directly from Symantec or from the storage manufacturer and installed on NetBackup Media Servers.
 
The vision for OST was announced in 2006 and made available in NetBackup 6.5. Most recently Symantec included OST functionality in Backup Exec 2010  calling the capability simply Symantec OST. Although both features are called OST there are separate Hardware Compatibility Lists for OST support in Backup Exec and NetBackup.
 
The OST API is protocol independent, meaning the hardware providers can utilize OST over whatever protocols are best suited for their devices including Fibre Channel, TCP/IP or SCSI.
 
The OST API provides 4 key features but the hardware vendors are not required to support all of them but rather just select the ones most suited for their devices.
 
OpenStorage Features
 
Direct Copy to dedicated tape drives
Direct Copy to shared tape drives
Optimized Duplication
Optimized Synthetics
One manufacturer that has strongly embraced OST is Quantum with their latest DXI Series appliances supporting both Optimized Duplication and Direct Copy to Shared Tape Drives. Using these features Quantum is able to replicate between DXI appliances or backup directly from a DXI to a tape library all while keeping NetBackup aware and the catalog consistent.
 
Depending on the intelligent storage device in use OST may also provide better performance than a standard Fibre Channel or NFS/CIFS interface. The OST API allows the vendors to coordinate communication and data transmission between the media server and the storage device in a way that traditional access methods cannot. The storage manufacturers can also leverage this technology for load balancing.
 
The list of manufacturers supporting OST continues to grow as do the ways in which they are taking advantage of it. As to how you get OST there are a number of pieces involved.
 
 
 
NetBackup includes OST as part of the Enterprise Disk Option and is licensed based on the Front End Capacity.
Backup Exec includes OST as part of their Deduplication Option licensed per media server.
The storage manufacturers typically offer OST support as an additional cost item.
 
The following link will take you to the Symantec OST page where you can also find the NetBackup Hardware compatibility list including OST supported devices and the specific features supported by each.

Do we have to create storage server type as open storage to use OST?

We are using Hp MDS6000 enclosure as storage box for backups writing to MSDP and replicate data using AIR to another MDS6000.In this scenario is that storage box OST device?

You may have configured the Hp MDS6000 as MSDP (Media Server Dedupe) storage?

This is currently the only STU (apart from PureDisk) that is supported with AIR.

Supported OST devices are listed in the NetBackup 7 Hardware Compatibility List (HCL):    http://www.symantec.com/docs/TECH76495

 

Supporting Storage Foundation and VCS on Unix and Windows as well as NetBackup on Unix and Windows

Yes, they have configured MDS6000 as MSDP storage.

MDS storage box has 120TB RAW ,they have raid10 on that and only 50TB is usable,30Tb they are using for dedupe and 5TB as advanced disk and rest is available
