How to delete a DataDomain storage system in NetWorker 8.2.3.

Jump to solution

Hi,

I'm trying to delete a DataDomain device (DDOS 5.6.2) from NetWorker (release 8.2.3).

I receive the error message "A device exists on the DDR.

When I check devices, there is no device for the DD device to be deleted.

Additional information: Several VLANs and several EBRs are used. Using the "new device wizard", I've created three Data Domain Devices to support the different EBRs in the different VLANs. Unfortunately, I've to delete two of those devices, because the devices hostname do not fulfill the requirements for DNS.

With kind regards

Michael

It seems to be related somehow to integration with VC - not sure if there is some extra dependency as I do not run such setup.  Best bet is to open a ticket with support.  Not sure if you could remove it by forcing it with nsradmin (for example, while NSR is down), but you may try that as well.

This makes sense as you should not be able to delete the whole DD.

Go to "Devices" (2 steps up), then select your DD device here.

  Unmount the media

  Delete the device

Hi Bingo,

and that's what's confusing me. There is no related device under "Devices". The NetWorker Device should be "Data Domain Systems name"_"Storage_Path". But there is no such entry. I've created a screenshots during the Device Creation:

The device from step "Adding Data Domain Device" is not listed under "Devices", as far as I remember I've deleted it already. The device is also not listed in nsradmin.

I thought that my problem is maybe caused, by the fact, that I've used the "New device Wizard" to create a new Data Domain System with a different IP of an existing one (to support EBRs in different VLANs).

Any further idea?

Thanks and regards

Michael

I also have DDs defined on each VLAN and could remove it in the past (didn't try with version you have) so that should not be an issue.  I wonder if some device leftover exists...  if this is on Linux, can you do following on backup server:

grep "evice access" -A1 /nsr/res/nsrdb/*/*

So, you are looking at the value of device access information and you wish to see if any is defined for DD VLAN path you have or wish to remove.  As this line is usually long and therefore escaped to new line, I used -A1 to list line below the one where I found the string I'm grepping.

Hi Hrvoje,

grep "evice access" -A1 /nsr/res/nsrdb/*/* didn't contain the device I want to delete.

I did also run grep -i DataDomainSystem-to-be-deleted -A1 /nsr/res/nsrdb/*/*
Output:

/nsr/res/nsrdb/09/27008f19000000002fd766580a4e605f:hosts: DataDomainSystem-to-be-deleted;

/nsr/res/nsrdb/09/27008f19000000002fd766580a4e605f-inuse filecopy streams: 0;

/nsr/res/nsrdb/09/27008f19000000002fd766580a4e605f:name: DataDomainSystem-to-be-deleted;

/nsr/res/nsrdb/09/27008f19000000002fd766580a4e605f-OS version: Data Domain OS 5.6.2.0-543944;

Maybe also interesting to know, when I run the "new device wizard" to add a new DD device, only one device is listed (the one I didn't delete):

Thanks and regards

Hi Hrvoje,

how could someone know all those details about NetWorker? You're right, stopping NetWorker on the NetWorker server, specifying the resource database manual (nsradmin -d /nsr/res/nsrdb) and afterwards deleting the DataDomain devices using nsradmin works. I'm happy and impressed.

Thanks a lot

Michael

Deleting a resource is not an issue - finding the right one is often more critical.

But beware of dependencies as NW will not be active to assist you.

BTW - I just verified with NW 8.2.4.1 that you can in fact successfully delete a DD from the NW Admin GUI.
