NDMP and Security
by Sean Hinchey 25 Aug '99

25 Aug '99

We have a UNIX machine running Netbackup. It is initiating backups to locally attached tapes drives on our filer. Can anyone explain how the filer knows it's supposed to allow the UNIX host to initiate backups? I would assume the machine/userid pair would need to be in the hosts.equiv before this would work. However, backups are working without this entry. How does security work with NDMP? -Sean ----- End Included Message -----

Hello Joe Spainhour, I owuld like to process an RMA for a motherboard replacement on the F330 that was experiencing SIO errors. If could can please provide me with the serial number to the filer and verify the shipping address I will process the RMA. I look forward to your response.

what's a good NFS write speed in MB/sec?
by Matt Harrington 25 Aug '99

25 Aug '99

I'm evaluating a NAS filer similar to the ones sold by NetApp and Auspex. This particular model is made by Nitech in Irvine, CA. These NFS vendors speak about benchmarks in ops/sec. It's more intuitive for me to think of benchmarks in terms of MB/sec throughputs for a large file write or read. My quick-and-dirty tests show that I can write at 1.8 MByte/sec over a 100Mbit network using NFS v3. I can FTP at about 7 MByte/sec. My question is: do these numbers seem reasonable? If not, what aspects of NFS should I tweak? ---matt p.s. methods: to make a 100MB file: dd if=/dev/zero of=/tmp/bigfile bs=1024 count=102400 time cp /tmp/bigfile /home/bigfile (where /home is the NFS server).

Netapp CIFS as part of DFS tree?
by Brian Tao 25 Aug '99

25 Aug '99

I got this question from one of our NT guys... can a CIFS-enabled Netapp participate in an NT DFS tree? From what I understand, NT's DFS looks and acts like UNIX-style directory mounts (i.e., instead of assigning a drive letter to a shared drive, the drive appears under an existing directory). -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

RE: Copying small directory on netapp
by Muhlestein, Mark 24 Aug '99

You can use 'scopy.exe' from the NT side. If you run it as Administrator it should preserve all UNIX and NT metadata, including symlinks, DOS bits, UNIX permissions, etc. Mark Muhlestein -- mmm(a)netapp.com -----Original Message----- From: Stephen C. Losen [mailto:scl@sasha.acc.virginia.edu] Sent: Tuesday, August 24, 1999 8:23 AM To: toasters(a)mathworks.com Subject: Copying small directory on netapp We are using our netapps for home directories in a mixed NFS and CIFS environment. We have a prototype new user directory that we set up with some unix "dot" files, a public_html directory, etc. Most of our CIFS users never touch unix, so from CIFS we make the unix dot files hidden. We do this in the hope that they won't delete them and then later on give unix a try and have problems when their account doesn't behave as documented. We use the netapp dump program to dump the prototype directory to a disk file. We create new accounts from unix. We make a new user directory and populate it with netapp restore. Then we chown all the files to the new user. This works great because it preserves the "hidden" attribute on all the "dot" files. Unfortunately, the netapp dump utility writes all the inode information for the entire filesystem to the dump file. So our little prototype directory, which tars into a file of about 20K, dumps into a 2.5M file. This really slows down bulk user adds, because it takes several seconds for each restore to run. Not a surprise when you have to rsh over 2.5M. We added 4700 accounts for our new incoming students and it took about a day -- almost all of the time taken up by restore. And yes, we dump once to file, and do multiple restores from it. I suppose I could build a very small and empty netapp filesystem and put the prototype in there and dump it. That would certainly reduce the size of the dump, but that's an impractial waste of resources. So here are my questions: 1) Is there some way other than dump/restore to copy a directory on a netapp that preserves all NFS and CIFS attributes? 2) We are running 5.2.2P1 and I don't see any dump flags that avoid including all the inode info in the dump. Am I missing something? 3) Is there a way from unix to set the CIFS hidden attribute? If so, I would just use tar and set the attribute.

Any CIFS client can be a destination in an NT DFS setup because of the way it works. If a path is to be rerouted, the client gets a special error, then asks the server for the new path. The client then issues a separate connection to the destination share, which can be on any CIFS server anywhere, including the filer.

This is an error in a pretty fundamental part. Basically, the message means that the PCI/ISA bridge chip (SIO - Intel 82378ZB) has a problem. Since this is just about the very first test in a filer at power-on, it could be indicative of a number things, such as clocks, interrupts, or PCI operation. There is no workaround. I think you'll have to RMA your motherboard. rgl R. Guy Lauterbach Manager, Firmware & Diagnostics Network Appliance, Inc.

No autosupport mail on reboot
by Graham C. Knight 24 Aug '99

24 Aug '99

Has anyone encountered this type of problem? After upgrading to 5.2.3 none of our systems send autosupport mail on reboot. I can issue an "options autosupport.doit test" command and autosupport mail is sent, but nothing on reboot. There is nothing in the messages file that indicates an error, also there is no message that autosupport has been sent. Here's what the autosupport lines in rc look like: autosupport.mailhost mailhost options autosupport.to autosupport@netapp.com,nac-admin@ast.lmco.com options autosupport.from nac-admin-reply(a)ast.lmco.com I don't see a whole lot of ways to debug this problem. Any tips would be greatly appreciated. Thx, Graham

SIO error on boot up.

We are getting SIO errors on an F330 while it is doing its POST. It then halts while trying to load the OS. Any ideas on this? Joseph

RE: Netapp CIFS as part of DFS tree?

We here at SAS do this all the time. You can do DFS mapping via the command line. Something like: dfscmd /map \\sashq\u\userid \\netapp_name\share_name\userid And the user will just need to go down to \\sashq\u\userid. They do not need to know where this area resids. MS DFS hides this from the user (Just like AFS/DFS does in the Unix world) Regards, Dawn -----Original Message----- From: Brian Tao [mailto:taob@risc.org] Sent: Tuesday, August 24, 1999 11:08 AM To: toasters(a)mathworks.com Subject: Netapp CIFS as part of DFS tree?
