This issue has been solved. See solution.

Hello Everyone,

We recently upgraded from DART 5.x to 6.x on EMC Celerra NS480.  All our NDMP backups are failing.  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.  All NDMP backups fail with error 99.  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 < Failed to get CIFS names for automaticTempNDMPCkpt914-50-1356152792 >

1356152802: NDMP: 3: Thread ndmp859 Cannot get CIFS names for source(/root_vdm_3/root_vdm_3/opcifs_d2)/ckpt
 
(/root_vdm_3/root_vdm_3/automaticNDMPCkpts/automaticTempNDMPCkpt914-50-1356                          152792).
1356152802: NDMP: 3: Thread ndmp859 Failed to start pax threads
"
 
But now it appears I have regressed and only get this error on Celerra:
 
"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: 3: Session 086 (thread ndmp086) NdmpdMover::connect: connect error: Connection refused
2012-12-27 18:55:07: NDMP: 3: Session 086 (thread ndmp086) Invalid state to stop mover (0).
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.
"
 
Any thoughts or pointing in a direction for help is appreciated.
 
Thank you

Have you tried to verify connectivity between Media server and Celerra with:

tpautoconf -verify <celerra_host>

Other than that - my only thought is to log a call with EMC...

Thanks for the response Marianne.  Here is the output of tpautoconf:

 

 

C:\Program Files\VERITAS\Volmgr\bin>tpautoconf -verify server_2
Connecting to host "server_2" as user "ndmp"...
Waiting for connect notification message...

Host info is:
  host name "server_2"
  os type "DartOS"
  os version "EMC Celerra File Server.T.6.0.61.0"
  host id "abc1997"
Login was successful
Host supports LOCAL backup/restore
Host supports 3-way backup/restore
 
Looks pretty good here.  I was also thinking that after the code upgrade on the EMC, it was restarted.  Maybe that affected the SCSI paths for the tape drives but they don't appear to have changed.  Pat on EMC looks same as what is configured on NBU side.
 
Unfortunately, the customer does not have a valid EMC support contract at the moment.  I'm performing CIFS level backups at the moment until I can sort through this NDMP trouble and the support contract is renewed.

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.

Please post output of :

C:\Program Files\VERITAS\Volmgr\bin>tpconfig -dnh

C:\Program Files\VERITAS\Volmgr\bin>tpautoconf -probe server_2

C:\Program Files\VERITAS\Netbackup\bin\admincmd\bpstulist -label <NDMP_stu> -U

 

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).
