NDMP backups with EMC Celerra DART 6

Question

Hello Everyone,
We recently upgraded from DART 5.x to 6.x on EMC Celerra NS480. &nbsp;All our NDMP backups are failing. &nbsp;Any thoughts on changes in this new DART version that are affecting this? We are running NBU 7.0 with Solaris master server and combination of Windows and Solaris media servers. &nbsp;All NDMP backups fail with error 99. &nbsp;Very little info on NBU side.
I was getting this error on Celerra:
"1356152802: NDMP: 6: Thread ndmp859 filterDialect could not be set - prereqs not met [pax_cmd_thread::setFilterDialect]
1356152802: NDMP: 3: Thread ndmp859 &lt; Failed to get CIFS names for automaticTempNDMPCkpt914-50-1356152792 &gt;
1356152802: NDMP: 3: Thread ndmp859 Cannot get CIFS names for source(/root_vdm_3/root_vdm_3/opcifs_d2)/ckpt
&nbsp;

1356152802: NDMP: 3: Thread ndmp859 Failed to start pax threads
"
&nbsp;
But now it appears I have regressed and only get this error on Celerra:
&nbsp;
"2012-12-27 18:55:07: NDMP: 6: Active NDMP backup/restore streams: 1, system configured concurrent streams: 4, maximum concurrent sessions supported: 4.

2012-12-27 18:55:07: NDMP: 6: Cleanup: Active NDMP backup/restore sessions back to: 0, system configured concurrent streams: 4, maximum concurrent sessions allowed: 4.
"
&nbsp;
Any thoughts or pointing in a direction for help is appreciated.
&nbsp;
Thank you

By googling, there may be something wrong on Celerra, but it is hard to point out.
You should open a case with EMC or post in EMC forum. They will provide various possible causes.

Have you tried to verify connectivity between Media server and Celerra with:
tpautoconf -verify &lt;celerra_host&gt;
Other than that - my only thought is to log a call with EMC...

Thanks for the response Marianne. &nbsp;Here is the output of tpautoconf:
&nbsp;
&nbsp;
C:\Program Files\VERITAS\Volmgr\bin&gt;tpautoconf -verify server_2
Connecting to host "server_2" as user "ndmp"...
Waiting for connect notification message...
Opening session--attempting with NDMP protocol version 4...
Opening session--successful with NDMP protocol version 4
&nbsp; host supports TEXT authentication
&nbsp; host supports MD5 authentication
Getting MD5 challenge from host...
Logging in using MD5 method...
Host info is:
&nbsp; host name "server_2"
&nbsp; os type "DartOS"
&nbsp; os version "EMC Celerra File Server.T.6.0.61.0"
&nbsp; host id "abc1997"
Login was successful
Host supports LOCAL backup/restore
Host supports 3-way backup/restore
&nbsp;
Looks pretty good here. &nbsp;I was also thinking that after the code upgrade on the EMC, it was restarted. &nbsp;Maybe that affected the SCSI paths for the tape drives but they don't appear to have changed. &nbsp;Pat on EMC looks same as what is configured on NBU side.
&nbsp;
Unfortunately, the customer does not have a valid EMC support contract at the moment. &nbsp;I'm performing CIFS level backups at the moment until I can sort through this NDMP trouble and the support contract is renewed.

Please post output of :
C:\Program Files\VERITAS\Volmgr\bin&gt;tpconfig -dnh
C:\Program Files\VERITAS\Volmgr\bin&gt;tpautoconf -probe server_2
C:\Program Files\VERITAS\Netbackup\bin\admincmd\bpstulist -label &lt;NDMP_stu&gt; -U
&nbsp;
I had Status Code 99 in a NBU 6.5 version and solved it re-creating the NDMP Storage Unit (my customer made the first one that I removed).
