This issue has been solved. See solution.

Hi ALL,

Nice to see you all !!

I am back from my vacations.

Can anybody tell me:

  1. How to create disk volume on storage server?
  2. Difference between disk pool and disk volume?
  3. Are disk volumes directories on storage server? like /tmp or /backup,manually created

1.  See the details in the admin guide (part I)

2. Disk pools are just a 'collection' of disk volumes, for example a disk pool may contain two volumes of 250GB each, giving a total available storage size of 500GB

3.  They need to be manually created, and should by filesystems, not directories.

Is it pure co-incedence that all of these users seem to have the same type of queries/doubts, theoretical questions?

 @ Martin:Thanks for the reply.

I first log in to my storage server.

I have total 2 TB space.

Now how much disk volume i can create manually and the command to create it?

A disk pool can represent one or more volumes. If a disk pool represents more
than one volume, NetBackup selects a volume for a backup based on: available
capacity and predicted size of the backup. NetBackup tries to write backup data
to a single volume. If necessary, backup images span volumes in a disk pool unless
the storage implementation does not support volume spanning. Backup images
do not span across multiple disk pools.
 
I just wanna know steps so that I can create disk volumes on my windows and unix storage server.

It's in the manual ...

http://www.symantec.com/docs/DOC5149

NetBackup_75_AdvDisk_Guide_20120309.pdf 

(Apologies, thought it was in admin guide, but that points you to the advanced disk guide)

Chapter 3 , page 15

To configure advanced disk pool is on page 36 - you need to read through from the beginning of the chapter though.

I am not sure why you are unable to look in the manuals yourself, it took me less than 5 minutes to find it.

I have read this.But it is not clear.

I have a Data domain st. server.open storage.And i want to create disk volume on it.

Just guide me with simple steps to create disk volume on it so that i can understand.

To create disk volumes is outside of NBU.

You need to use OS disk management tools or Storage Foundation.

Go speak to your OS System Administrators.

Once a drive letter (Windows) or a mount point (Unix/Linux) is assigned to the volume, you can start reading in NBU manuals how to use/configure these volumes into disk pools.

To create disk volumes is NOT part of NBU. Same as NBU unable to create tape devices.
ALL devices (disk and tape) need to usable at OS level before configuring them in NBU.

Thanks in advance

HI,

Apologies, I have no idea - I don't think I've ever logged onto a DataDomain in my life ....

You need to spearate the issues into the correct support forums ...

Connect forum - NetBackup issues only

EMC forum - data domain issues

@Martin:Can you please provide me the disk volume creation on storage server if it is not data domain.

As Marianne has correctly pointed out you use the OS dsk management tools or perhaps VCS as it is commonly used.

The most basic way to create a volume that can be configured as advanced disk, is to create a filesystem.

The requirements for Advanced Disk are listed in the Hardware Compatibility List:

AdvancedDisk Arrays

NetBackup 7.x offers advanced data protection functionality with any disk array that can be mounted as local disk to a NetBackup Media Server. Enterprise Disk Option licensing is available for disk-based arrays or appliances (e.g., VTL or OST) that provide deduplication and/or replication functionality.
 
Please note the following for AdvancedDisk array support:
1. An AdvancedDisk array is used by NetBackup as a backup destination, not a backup data source.
2. It is intended that AdvancedDisk features will work with any mounted file system or NFS. The storage must be seen as local disk by the NetBackup Media Server.
Common file systems available on NetBackup Media Server-supported operating systems are supported. CIFS-connected storage is supported with NetBackup 7.0.1 and later.
3. If using Veritas Storage Foundation, please refer to the Veritas Storage Foundation Hardware Compatibility List <http://www.symantec.com/docs/TECH47620> for a list of supported disk arrays.
4. Connection method of the disk array (parallel SCSI, Fibre Channel, iSCSI, etc) is not a determining factor for support, only that the storage is seen as local disk by the NetBackup Media Server.
5. AdvancedDisk functionality is subject to all functional limitations as imposed either by the operating system or by the underlying file system.
6. For UNIX NetBackup Media Servers, AdvancedDisk requires that all LSUs (Logical Storage Units) are active mount points within the UNIX host. Using the NFS automount feature is not recommended with AdvancedDisk.
7. Access to NFS storage requires NetBackup daemons to run as root. The NFS server exporting the file system must be configured to allow root access to the file system.
8. To ensure support, the disk array must be combined with interconnect hardware that is supported by the disk array manufacturer and the operating system vendor.
Refer to the respective vendor's support lists for this information.
9. When installing and configuring HBA drivers it is recommended that the array vendor-qualified HBA drivers be used as opposed to the general HBA drivers that are
released for each operating system. These array vendor-qualified HBA drivers are typically found in a separate section of the HBA vendor or array vendor's website, often separated by array model.
10. Performance may vary depending on the array hardware used.
