na_macstream utility from Network Appliance
by Allen, Pat 08 May '01

08 May '01

Hi all, Does anybody have any experience running the na_macstream utility that is supposed to convert all the DAVE Macintosh Client resource.frk files after upgrading to 6.0.1R3? I upgraded this morning and immediately ran the utility as instructed. Whenever it finds the resource.frk file, it gives me an error message that says that it can't delete the files under that directory name. A couple of questions: 1. Is this error message common? (I'm running in verbose mode.) 2. Are the resource.frk directories necessary after running the na_macstream utility? Thanks! --- Pat Allen (pat(a)mbari.org) Monterey Bay Aquarium Research Institute (MBARI) 7700 Sandholdt Rd, Moss Landing, CA 95039 (voice) 831-775-1724; (fax) 831-775-1620

Michael, Perl runs on Win32 as well... check out ActiveState.com. I've taken many Perl scripts & ported them over without any significant difficulties. The resource kits for NT/W2K are your valuable friends in these efforts as well. -----Original Message----- From: Honeycutt, Michael [mailto:MichaelHoneycutt@NC.SLR.com] Sent: Tuesday, May 08, 2001 7:43 AM To: 'toasters(a)mathworks.com' Subject: Quota Notifier Does anyone know of a program or tool that I could use to report to my users when they are close to their quota limit? These are NT clients, so I need something that will run from a windows platform. I have seen the perl scripts on the NOW site, but I am not familiar enough with Sun to make those scripts run correctly. Thanks. Michael Honeycutt MCSE/A+ NT/Exchange Engineer IBM Global Services

RE: Maximum volume size
by Wedge, Cliff 07 May '01

What docs are you reading? Thanks, Cliff Cliff Wedge Technical Publications Manager Hardware Group Network Appliance 408.822.6839 cliff.wedge(a)netapp.com -----Original Message----- From: Leigh David Heyman [mailto:leigh@ai.mit.edu] Sent: Monday, May 07, 2001 1:56 PM To: toasters(a)mathworks.com Subject: Maximum volume size So, I've been through some docs, and they seem to say that the maximum "recommended" size of a single volume is 250G. With 36G drives this equates to basically 1 volume per shelf???!?! Is this correct, or has the documentation in this regard not been updated? Does anyon know what this "recommendation" is based on? It doesn't seem very efficient. -Leigh ----------------------------- A nasty looking dwarf throws a knife at you.

Backup trouble - "Compression page" support
by Jered Heeschen 07 May '01

07 May '01

I connected a Magstar 3590 tape drive to the external SCSI port on an F760 running DataONTAP 6.02, and have been having trouble getting the filer to do more than recogize the tape's existence. The drive is recognized when I execute "mt -f nrst0a status", and shows up as I'd expect in "sysconfig -t", but any other tape operation fails. When I execute any "mt" command (including "status") I get the follownig error on the console: " [...:tape_admin:error]: tape 0.0: doesn't support compression page". I've tried mt with rewind and offline, and both fail. Attempting a dump yields a message that the tape is not writeable or is broken, and requests a new one. I've tried this with two different 3590 drives, two different SCSI cables, and three different tapes. I've also cycled through the different tape deivces (rst0a, urst0h, nrst0l, etc.) with no change. Anyone have an idea of what else I could try to get the tape drive and the F760 to get along? Jered Heeschen heeschen(a)us.ibm.com

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

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

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
