DataDomain Device dimounted randomly
Hi,
We have experienced a fialure with our DataDomain 670. This night some device in Networker were dismounted, without any apparent cause.
We remount these devices without problem and the backup run good. But why were these device dismounted?
We are using Networker 7.6.4.1 and DD has OS 5.0.2.
Anyone has an idea?
Thanks for the help.
Regards,
Greg

Hi,
Please provide the daemon logs from NetWorker server. Also try to restart the NetWorker Services and rename tmp folder.

Hi,
We already have restarted Networker server after to renaming tmp and jobdb folder.
Here you will find the daemon.raw for the restart.
You can see at 9/13/2012 3:35:03 PM the first error of this kind.
We have active the RMAN Backup of our SAP system yesterday. Before that, we never see these errors.
Thanks for your help.

You should also examine the operating system log(s) on your NetWorker storage node, as well as the logs inside the DDR ('log view ... ').

Do you have AMM enabled for that device?

Hi Hrvoje,
As we use a DataDomain, I'm not sure to understand well your question. Were can I see that?
Thanks a lot.

In properties for device - in NetWorker (eg. using NMC), check if auto media management for that specific device is enabled. In the past, with NFS or CIFS based devices, something like that used to happen and then enabling AMM did the trick.

Which DD 5.1 did you go to? I have two DD890 landing at the DC and O also decided to go with DD 5.1 (since 5.2 still didn't get GA status though I have been told it is stable).

OS: 5.1.1.0-291218
And we have two DD670 in our DC.
EMC guys told us not to update to 5.2 yet as this version seems to be a bit too new

Hi,
Finally, it's seem that Auto Media Managment has to be used too with DataDomain Device. It works perfectly and The EMC support told me they are gone to update the documentation.
