Alas the NDMP standard describes that error as:
NDMP_XDR_DECODE_ERR (Generic Error)
Error decoding message.
Not exactly helpful! You could perhaps look in the path
/vol/mediavol/.snapshot/hourly.0/
(or the /vol/mediavol path) and make sure that there are no files with corrupt
file names, or non-printing characters in the file names. Though I guess you
may be using it as FCP, I'm not clear. Also there sound to be issues if the
number of files is very large.
There are plenty of examples of this error if you Google, one might match. A
useful piece of advice in one was to look at the filer's log:
/vol/vol0/etc/messages

Subject: [Veritas-bu] NDMP backup failure.
Hello..
We are recieving the below error message while trying to backup NDMP host. We
have been backing up our SAN (Netapp) data using NDMP since an year. But this
error is seen from past 3 days.
30/04/2010 18:02:30 - mounting T1W3FR
30/04/2010 18:03:07 - mounted; mount time: 00:00:37
30/04/2010 18:03:07 - positioning T1W3FR to file 1
30/04/2010 18:03:10 - positioned T1W3FR; position time: 00:00:03
30/04/2010 18:03:10 - begin writing

ndmp_message_process_one_failed, status = NDMP_XDR_DECODE_ERR
30/04/2010 18:04:27 - Error ndmpagent(pid=4260) NDMP backup failed, path =
/vol/mediavol/.snapshot/hourly.0/
30/04/2010 18:04:56 - end writing; write time: 00:01:46
NDMP backup failure(99)
I also ran tpautoconf command and recieved the following output.
Connecting to host "san1" as user "svcSanBackup"...
Waiting for connect notification message...
Opening session--attempting with NDMP protocol version 4...

Inquiry result is "ADIC Scalar i500 520G520G.GS003 "
We recently enable SMB and signing on SAN. Would this cause any issues?
