RE: move data within CIFS
by Knut Kristan Weber 29 Feb '08

29 Feb '08

Hi again, of course robocopy is exactly the wrong tool. Using robocopy on any server will grant that all the data is transferred via LAN. And it has a lot of options like purge and mir, but it can never move data within a partition without really transferring them. A move within the same drive letter on a windows server will take less than a second because only the MFT is changed and no block of real data transfered.

ndmpcopy would certainly work and be faster than a cifs file copy.

Knut, I think you will find you can use wildcards with the mv command (mv /vol/vol1/data1/sub1/* /vol/vol1/data1 ß that would take EVERYTHING under sub1 and drop it under data1) Of course, as Michael mentioned this should be tested first either with the simlautor, or on a test vol. Good luck. Brett.

> Have you tried qtree snapmirror? > Not sure if this will help, since it's the same volume. Hi thanks, Michail, a snapmirror would leave the structure in whole as it is. Also snap restore is no solution: If restore_as_path is specified, the path must be a full path to a filename, and must be in the same volume as the volume used for the restore. Files other than normal files and LUNs are not restored. This includes directories (and their contents), and files with NT streams. So you cannot restore directory X as directory Y.

in-line tape copy possible ?
by George Kahler 28 Feb '08

28 Feb '08

Hello, I haven't checked with Netapp yet, but would anyone here know if it is possible to have a ndmp backup going to two tape drives , thus creating a duplicate copy ? I have a dual port HBA for the tape drive(s) on a FAS3040 head with DOT 7.2.2. The drives are IBM LTO3s and the backup software is NetBackup version 6.0MP4. I would like to add a second tape drive on the the HBA and do the in-line tape copy rather then duplicating the data at a later time. Thanks, George Kahler York University

RE: autosupport stops functioning
by Webster, Stetson 28 Feb '08

As a former TSE myself, I can think of some possible situations where a customer can have this feeling while the TSE has a legitimate request. For example, you must be absolutely sure that the problem is in fact occuring during the Perfstat and packet trace, or it's irrelevant. Ideally you would have control to duplicate the problem at will and then capture it. If not, we have to be 100 % sure of what we are looking at (and for). I don't know what the situation was and can't speak definitively for it. All I'm saying is that sometimes context and sequence can be the only difference in an otherwise complete duplicate request for output. If I gave it some more thought, I'd probably think of more similar examples, but I think this is a good illustration. I hope this helps. Cheers .....

Changing Disk Ownership
by Michail Michalakis 28 Feb '08

28 Feb '08

PLEASE HELP *** I'm in the process of planning to change the disk ownership from hardware to software for various reasons. I've found alot of documentation for doing this on single node system, but none for a Cluster Environment. Has anyone done this on a FAS3050C or does anyone know the procedure? the part of booting into maitence mode and disk upgrade_ownership I understand. My concern is do I uncable the two node or what?
