NetBackup Accelerator

Hi All,

i am unable to enable accelerator feature for ms-windows policy - wehn i try i get the message - "To use the accelerator, select storage units from supported storage server: PureDisk Deduplication (PDDO), Media Server Deduplication (MSDP), Symantec clouds, and other qualified storage servers"
- policy storage type is PureDisk"

NetBackup 7.5.0.6

Policy storage - PureDisk

i wondered if anyone has had this problem, i have so far carried out the following:-

1 - checked license info and can see listed - Feature ID      = 88 Accelerator +

2 - have updated the device mappings file and running on version 1.119

3 - have tried creating the policy from the EMM server - but still get the same error.

i have followed these ref docs - http://www.symantec.com/business/support/index?page=content&id=TECH189730 and http://www.symantec.com/business/support/index?page=content&pmv=print&impressions=&viewlocale=&id=HOWTO68476 and still no joy

i plan to upgrade to 7.6 but my current version should enable me to us this feature

Many thanks for any assistance...

Tracy

It should - your Storage Servers have upgraded but not your disk pools

So just use:

nbdevconfig -changedp -stype PureDisk -dp [disk pool name] -setattribute OptimizedImage

And you should get the last flag set as required - then your policy should work!!

Fingers crossed!

Exactly what "PureDisk" are you using and where is it located?

In the policy are you selecting that specific storage unit or a storage lifecycle policy?

Show us a little more detail of what you have and what you are doing

Thanks

Hi Mark

thanks for your response

apologies if i was not clear - i have created a test policy to see how this works - i am selecting a storage unit with MSDP installed which is a disk on a media server running 7.5.0.6

the policy is a ms-windows policy running a full backup with client side dedupe disabled as the dedupe will occur on the MSDP on the media server

when i tick the 'use accelerator' option i get the message described in the above post

Regards

Tracy

A few more questions...

Are you all on Windows?

Are you using the Windows or Java Console to set this up?

Do you have NBAC enabled?

Was the Media Server with the MSDP pool upgraded from an earlier version of NetBackup (7.0 / 6.5)?

I asked about if you were using STU Group as this can also cause issue - such as this : http://www.symantec.com/docs/TECH209889

 

Tracy_Fry

yes - all on windows

i'm using the windows console

don't have NBAC enabled

the media server with MSDP was upgraded  - we started with 6.5 but have upgraded as new releases came out

i have tried the suggestion in http://www.symantec.com/docs/TECH209889 and i still get the same error trying to enable the accelerator

OK - I have had this happen to me and the Storage unit needed upgrading (just via a command line)

I will dig through my notes to try and find the command for you... bear with me

Can you show me the output if this please:

nbdevquery -liststs -stype PureDisk -U

My thought is that the disk pool / storage server has not got the optimised image flag as it has been upgraded from 6.5

If the above command does not show this line:

Flag          OptimisedImage

as the last line then that would cause the failure

To fix that run the following commands:

nbdevconfig -changests -storage_server [storage server name] -stype PureDisk -setattribute OptimizedImage
 
 
nbdevconfig -changedp -stype PureDisk -dp [disk pool name] -setattribute OptimizedImage

You should then be able to use it in your policy - hope this is the reason!

Try it against the disk pool too:

nbdevquery -listdp -stype PureDisk -U

Just in case it is the disk pool that doesn't have the flag

ok so have run it against the disk pool and get the following

should the flag be set here as well?

It should - your Storage Servers have upgraded but not your disk pools

So just use:

nbdevconfig -changedp -stype PureDisk -dp [disk pool name] -setattribute OptimizedImage

And you should get the last flag set as required - then your policy should work!!

Fingers crossed!

Good Morning Mark,

That did it! - I ran nbdevconfig -changedp -stype PureDisk -dp [disk pool name] -setattribute OptimizedImage and the OptimizedImage flag is now present and i am able to enable the accelerator feature.

Thank you very much for your help,

i had searched a lot of symantec documentation and could not find any reference to this at all

Have a great weekend

Tracy

Some additional information for this solution. This worked when i used the admin console from the media server where the device_mappings.txt was located here - installpath\VERITAS\NetBackup\var\global\device_mappings.txt

In order to make this work from my machine i had to copy the device_mappings.txt file to the same location - see the following tech note - http://www.symantec.com/business/support/index?page=content&id=TECH189730

Glad you are sorted - had this happen to me on one site .. first the accelerator option was greyed out as we had a dodgy license key, once we got a new key it didn't work for a very similar reason to yourself ... just had to dig through all of my notes / e-mails to jog my grey matter of what the commands were

 

Tracy_Fry

Yes, I had to get an updated license key as well! Let's hope the results are worth it....

Thanks again.
