NDMP ClusterAwareBackup to Tape Netapp cdot

[Marcel123]

Hello ,

so we searching after upgrading to 7.7.3 a Solution we has open Tickets against support but now for more than 1 Month and nothing helps ...

The Setup 

Inventory

Netbackup 7.7.3 on Redhat Linux 6.

Netapp 4 Node Cluster.

svm on the cluster for cifs/nfs.

I500 Tape LiB with Lto6

data(svm)

cluster(cluster svm)

nbu1 (master)

nbu2-7(media)

Config

NDMP  Credentials stored for :

cluster

data

SLP:

cdot Snapshot and than  BackupFromSnapshot to Tape

Policie :

BackupNDMP

Included the data svm as NDMP Node and the Volume that we want save.

Problem:

The backup Run's, after the Tape Backup is finished we get an error :

10/27/2016 08:58:27 - Info bptm (pid=10930) EXITING with status 23 <----------
10/27/2016 08:58:27 - Critical bpbrm (pid=10922) unexpected termination of client data

I we look in the the bptm log :

So we found out that we can disable the NDMP Mover than the backup run once.

After that the backup run once, the next backup get the error (these error come also if the mover is enabled.) :

Only one NDMP backup of a snapshot per backup ID is allowed  (1567)

So now im lost.

I has to  change the names so it's posible that nothing changed alll...

So any help would be very welcome .

I do not have 1st-hand experience - just bookmarks for the day I may need to.

Please compare your config with these TNs:

http://www.veritas.com/docs/000025335 

This one seems to be for pre-7.7:

Been awhile since I have worked with NetApp, but the first thing I notice is this line:

<8> retry_getaddrinfo_for_real: [vnet_addrinfo.c:1108] getaddrinfo() failed RV=-2 NAME=cluster SVC=0 errno=2

which seem to indicate a name resolution problem.

Another thing that used to be an issue was that the tape drive order on the filer changed unless you used the Netapp version of persistent binding. Was some entries in the rc file back then.

NetBackup status code: 1567
Message: Only one NDMP backup of a snapshot per backup ID is allowed
Explanation: A backup policy of type NDMP refers to an SLP that contains more
than one Backup From Snapshot operation.
Recommended Action: Do one of the following:
¦ Modify the SLP so that it contains only one Backup From Snapshot operation.
¦ Modify the backup policy so that it uses a different SLP.

Thanks all for the posts.

So i found out after DebugLevel 9 that the Cluster-node that served the data build up active an NDMP Sesssion with the Master Server.

These Connection was frobidden in the Firewall.  So for all reading this, it is really nessary that all node managment lifs can comminicate with your master   / media server.

It is not sufficiant that only the cluster lif can communicate with the master.
