DP 6.2 backup to HP D2D Nas mode - Cannot Write to Device

Hi,

 

We Use HP DP6.2 on Windows 2008R2 server to backup all of our servers and Desktop.

The backup Device is HP D2D configure in NAS mode, so in DP6.2 we create File librairy Device, to configure we follow the instruction in the "hp_D2D_NAS_integration_w_Dataprotector" guide.

Sometimes in certain backup Job we get an error "Cannot Write to Device - Network Name is unvailable"

with the unc path to the D2D Nas folder (\\192.168.10.20\Windows_XP\51acf8a154ff32a85507285012d.fd)

If i check after the backup for this file, i could find it on the NAS.

but the backup was failed.

And other backup job successfull

 

Backup Log:

Re: DP 6.2 backup to HP D2D Nas mode - Cannot Write to Device

Hi,

 

can you please translate the french error messages to english?

Which patches are installed on the system. How many concurrent backusp are running? Is the error always for the same Writer or will it change from backup to backup?

 

Best regards

Daniel

Hi,

 

The translation is something like :

Major] From: BSM@backup_server"D2D_Windows_XP_Writer3" Time: 03/07/2012 19:54:14

[90:51] \\192.168.10.20\Windows_XP\51acf8a154ff32a85507285012d.fd

Cannot write to device ([64] Specify network Name unavailable. )

 

[Major] From: BSM@backup_server "D2D_Windows_XP_Writer3" Time: 03/07/2012 19:54:16

[90:51] \\192.168.10.20\Windows_XP\51acf8a154ff32a85507285012d.fd

Cannot write to device ([6] invalid Handle )

 

There was no Patch on the Manager.

The Probleme Occurs on different Jobs and different Writer.

There was only one job ate the Time that use this Writer.

Re: DP 6.2 backup to HP D2D Nas mode - Cannot Write to Device

Could you please provide information on the D2D model and installed firmware? How many different media agents are writing to the same device? Is that client really Windows XP? Have you configured multiple media agents to write to the same share/directory in the share?

 

Regards,

Sebastian

Re: DP 6.2 backup to HP D2D Nas mode - Cannot Write to Device

Hi,

 

The D2D is a 4112 G2, with 2.2.14e Firmware Version. (the last i think)

The Data protector server is the only media agent that's write on the D2D.

and i've configured 4 writer on this Share for simultaneous write, and yes the client are Windows XP.

But this problem sometimes Occur on another Windows 2003 servers backup jobs.

 

Regards,

 

Frederic.

Ok, just make sure you've followed the integration white paper and check if the CIFS timeout might be your issue.

HP D2D Backup Systems default Windows CIFS timeout value too low for some NAS backup operations to complete

Hi Sebastian,

 

thanks for your answer, i'll  create the registry key for the CIFS Timeout and check the backup job during the next days.
