Re: HSM with filers?
by SteveRoche＠datalink.com 07 May '01

Tom, This was sent to me some time ago from Darleen Cormier from Netapp. -steve Hi Steve, The reason that neither Veritas Storage Replicator or other HSM packages currently support HSM migration of data to and from NetApp filers is because DataONTAP does NOT support DMAPI protocol. DMAPI means Data Management Application Programming Interface and this along with the X/Open Data Storage Management (XDSM) standard allow HSM functionality across a wide range of operating environments without sacrificing system reliability. Without this, the HSM software has no idea of file attributes or location. This reason I'm giving you all this exciting info (YAWN) is that most, if not all, HSM packages use these protocols. Until NetApp is able to support these protocols, or the 3rd party companies are able to come up with some other way of doing HSM, we will not be able to offer an HSM solution to our customers. Now, Good news/ Bad News. The good news is we are receiving more and more requests for this functionality, and I do know that engineering is looking at possibly adding support for the DMAPI protocol. The bad news is that no date has been set for beginning to implement this. Sorry we can't tell you anything better.

Does anyone know of any HSM products out there that currently work with filers? Thanks, Tom

CIFS plaintext vs encrypted
by Frank Cusack 07 May '01

07 May '01

From http://www.netapp.com/tech_library/3020.html: The NetApp filer requires plaintext password authentication from the client if the /etc/passwd file or NIS is used to provide CIFS client authentication on the filer. If the filer is configured to provide Pass-Through Authentication then any password entry in the /etc/passwd is ignored for NT authenticated CIFS clients. How do I know how my filer is configured? Also, what about NetLogon authentication? cifs testdc does find my domain controller, but does that mean it is in the domain? Also, cifsconfig.cfg: cifs setup -w x.x.x.x -security unix -cp 437 Oooh, I'll bet that means plaintext (against local /etc/passwd). Hope not. I realize my question may be incomplete. :\ thx /fc

dump/restore inode question
by Avi Freedman 05 May '01

05 May '01

Perhaps a stupid question, but if I restore a dump from a tape/file to a volume on a netapp, and there are inode number conflicts (because the existing volume has a bunch o' files), will the files with duplicate inode numbers be blown away? Thanks, Avi

NNTP question
by Avi Freedman 05 May '01

05 May '01

For people running netcaches with NNTP support, I was wondering about how many simultaenous users worth of activity you've been able to support on 600/700-series netcaches. Thanks, Avi

Large volume performance
by Tom McDonald 05 May '01

05 May '01

Hello, We have a need to create a very large volume (800+ GB) on one of our F760 Filers for NFS only use. I plan on creating a volume with 5 RAID groups, each with 14 18-GB disks, that will span across two fibre channel adapters. RAID groups will not span across adaptors. I am wondering what kind of performance should expect as a result of having such a large volume across two adapters. Any thoughts? Thanks, Tom

What you are saying is true, Joe. A customer does not buy Veritas' Storage Migrator and then buy Enigma Data. Enigma Data has Veritas Storage Migrator already integrated into their "stuff". Veritas' package, by itself, is not compatible with filers. -----Original Message----- From: Joe Luchtenberg [mailto:joe.luchtenberg@data-line.com] Sent: Friday, May 04, 2001 8:59 AM To: 'Cormier, Darleen'; 'Tom "Mad Dog" Yergeau'; 'toasters(a)mathworks.com' Subject: RE: HSM with filers?

Re: JNDMP Copy

In addition to the suggestion to make sure ndmpd is on on the filer ("ndmpd on" will do it) try the transfer using paths that look like this: jndmpcopy gvl-netapp1:/vol/vol1/~snapshot/SnapSQL/gvl-triv-sql01/DATA/LOG gvl-netapp1:/vol/vol1/gvl-triv-sql01/TEST Note: All I did was remove the "c:" from the path.

RE: Help With Dump of a Filer 760
by Cormier, Darleen 04 May '01

04 May '01

Hi Irene, Please let me try and answer your question about sequential mode. The NetApp dump and restore utility has no way to control the robotics in a library. We do not have commands which tell the robot arm go to slot 3 and move the tape to drive 2, etc. Normally those types of commands are handled by the backup software packages. When a library is setup to respond to those types of commands, it is called "Random Access Mode". Most libraries by default are set that way. However, many, not all, libraries can also be set in "sequential or stacker mode". This means that the library simply moves from slot one to the next sequential slot. It can't "jump around", it just goes from the top to the bottom. Our dump utility will start at tape one, fill it up, eject the tape, insert next tape, fill it up, etc. When the library is set in sequential mode, we can control those basic functions. That is why it was suggested you set your library in that mode, however, I suggest you check with STK t! o see if your library has that option. Hope this helps. -----Original Message----- From: Reed, Irene [mailto:IReed@tea.state.tx.us] Sent: Wednesday, May 02, 2001 3:19 PM To: 'toasters(a)mathworks.com' Subject: Help With Dump of a Filer 760 We currently own a Filer 760 running ONTAP 6.0.1.R3. Currently we are backing up Unix files via nfs mounts. Soon we plan to put a lot of NT data on the filer that needs to be backed up. Our agency backup software is Legato 6.01 running on AIX 4.3.3. This version of Legato is non NDMP aware so we cannot use it to backup the filer. I am considering buying a StorageTek L20 (10 slots with 1 DLT7000 drive) and attaching it directly to the filer via the onboard scsi adapter. I would like to use dump and restore to carry out the backups so that I do not have to buy another backup software solution. Netapp says this will work if I can put the L20 in sequential mode. Does anyone know what this means? Is anyone backing up a filer in this manner? If yes I would love to hear from you. Also any suggestions would be greatly appreciated.
