have you tried this command:

/nas/sbin/server_user server_2 -passwd ndmp

Thanks dynamox for your response.

I  reset ndmp account on data mover 2 &3

I need to update the password to backup admin to configure on netbackup side?

I noticed server_log msg it says

2011-03-21 16:22:33: NDMP: 3:  md5 auth failed

When did you changed the param? Have you reboot DMs after that? Do you still have ndmp_md5 at the end of the line in password file for user used in NDMP config?

this param set long back.

yes i see _md5 in password file..

still i notice md5 authentication failed in server log..still working on this issue.

Any idea why i get this message?

delete the ndmp user with

# /nas/sbin/server_user server_2 -delete user_name

recreate it with

# /nas/sbin/server_user server_2 -add -md5 -passwd user_name

verify it working, using ftp and the newly created user against an IP interface of the datamover

Hi Peter,

Thanks for your help.I have recreated this user ndmp on celerra on both datamovers.

ftp connection from control station to data mover ok.

On media server i tried to verify this command

# tpautoconf -verify sggs-0100
Connecting to host "sggs-0100" as user "ndmp"...
Waiting for connect notification message...
Opening session--attempting with NDMP protocol version 4...

Still host authentication fails?Any idea how to verify ..
