Lost with NDMP
Hello, I am working on tests with various software backup systems to attempt
to backup our netapp fas270 filer. I recently acquired netbackup 5.1 from our main site and put on a test lan to attempt to do a tape backup from the filer to the netbackup server attached tape drives. I attempted with ndmp and figured out (I think) the authentication process because when I use the ndmp_auth program on the server it replies succesfully and a "success connect" shows up in the filers messages file. But everytime I attempt to run a test backup job, it fails with the response of something like "Connection refused". I'm writing this from home so am relying mostly on memory. Is there something I'm missing? Do I have to tell the filer to share the selected backup volumes to ndmp or something or another? Network connections are 1gig fastether server is dell 2850 with w2k3 Nothing shows up in filer /etc/messages for failures.nor the w2k3 event logs. I have the iscsi license for the filer and was thinking of going that route by loading the microsoft iscsi driver on the server. Sadly though I'm about as lost on this method as well but am eager to hear feedback, positive or negative. Thanks for any help Syd |

Check you're options: ndmpd.access all ndmpd.authtype challenge ndmpd.connectlog.enabled off ndmpd.enable off ndmpd.ignore_ctime.enabled off ndmpd.offset_map.enable on ndmpd.password_length 16 ndmpd.preferred_interface disable (value might be overwritten in takeover) NBU can't do challenge for authtype, or at least not pre-6 that I know of. Also, if you have something other than 'all' in access you need to make sure one of them is the NDMP client. ~F |

All of the options have been checked and there is no challenge set for authtype and "all" is in place for access. As I mentioned, when testing for login with the command prompt on the netbackup server, the filer accepts the session. It just fails with trying a manual backup. Syd |

Syd It sounds like it should work then, but I've not yet done any testing with 7.x and there's alot of new stuff in it. Looking on NOW very quickly I found: Empty the old configuration file for NetBackup on the Backup Master; it can be found under /usr/openv/volmgr/database/.namespaces.chksum. May want to try that and see if it helps. If you can capture actual settings and messages that may help here as well. ~F |
