Who to buy additional drives from?
by David L Kindred (Dave) 16 Apr '03

16 Apr '03

I need to add some drives to the DS14 on our F810, but had a couple of questions. Since the Filer has performed so well, I haven't had much need to deal with it, which is good, but it also means I'm not as familiar with it as I'd like. It seems I only have time to learn about the things that break :( I have been able to find answers to the technical questions on NOW, so I don't have to act stupid about those. I do have one non-technical questions left though: When the time comes to buy the drives should I go back to the VAR we bought the system from, or direct to NetApp, or should I consider some other source? We are maintaining NetApp support, so we would need an "approved" vendor, etc. Thanks. -- David L.

RE: Reassigning low UIDs
by Ben Rockwood 16 Apr '03

16 Apr '03

The generally accepted low bound is 500. Which goes for both UIDs and GIDs. As for re-assigning, sounds like a job for PERL or some expertly crafted "find" commands. You could create an index in a 2-dimensional array (or just a flat file) mapping new to old UID and then just spider the mount points in question. Just make sure you heavily test it prior to unlessing it. benr. -----Original Message----- From: Jim Davis [mailto:jdavis@cs.arizona.edu] Sent: Wed 4/16/2003 10:43 AM To: toasters(a)mathworks.com Cc: Subject: Reassigning low UIDs Our Unix-side password files go back to the days of SunOS 3.x (if not before), so we have some users with UIDs less than 100. Nowadays this causes problems with NFS on, eg, Linux boxes that seem to assume any UID under at least 1000 is fair game for placeholder accounts. After struggling with this for a while it looks like it's time for a wholesale UID reassignment for those users. - what's a "safe" lower bound for UIDs? 1000? 10000? We'd rather not have to do this more than once! - is there some slick way to reassign UIDs en masse on a filer? We could run 'chown -R ...' on the admin host, but is there a better way?

tmp files

I use a SRM product to manage our storage and have noticed an abundant amount of Microsoft temp files which start with ~. I know these are created as a backup 'till the file is saved but we have way to many.... any ideas. Thanks Steve

RE: CIFS in Workgroup mode

If you are running with ONTAP 6.1.1 or later you can create up to 96 local users in workgroup mode and use NTFS security with NTLM authentication. Even without local users you can use UNIX-style security if you are willing to use /etc/passwd accounts (which unfortunately implies the use of plaintext passwords over the wire during CIFS login). However, it is true that for the very best available CIFS security (which uses Kerberos authentication) you do have to have the filer installed in a Win2k domain. Mark

Alan, You hit the nail right on the head as we say here in the States.... We recently met with a Novell SE and he espoused the same things you did. You've been there and done this??? Option 2 gets my vote.... however I've been asked to conduct an experiment with Option 1 in our lab. Yes Option 1 implies that every packet that comes from the Filer is dissassembled on the Novell gateway machine and reassembled outbound in the format defined. (NCP, HTTP, FTP and yes CIFS and NFS!!!) Sigh.... Onward....

Yes. We have FC7, FC9 and DS14 on the same loop. The rules are - the shelves must be linked in order of oldest to newest - FC7 -> FC9 -> DS14. You cannot have more than 56 disks on one loop.

"df" output on filers running 6.3.1R1D1
by Carl R. Friend 16 Apr '03

16 Apr '03

G'day. Does anyone here happen to run ONTAP 6.3.1R1D1 on a filer with more than two volumes on it? If so, what order does a "df" command on the console report them in? We just upgraded a two-volume filer to 6.3.1R1D1 and the reporting order reversed itself from vol0, vol1 to vol1, vol0. This, in turn, goofed up the SNMP monitoring bits by reversing the index-to-volume numbers.

RE: CIFS in Workgroup mode
by Alan McLachlan 16 Apr '03

Robert, One problem is that in workgroup mode NTFS security isn't available. In fact, no real security is available... There appear to be two options to using a filer in a Novell environment: 1) The "gateway" Novell server approach. This involves using a Novell server running Novell NFS Services (with lots of CPU and RAM) with a direct back-to-back link to the filer to act as an I/O path. Clients and application hosts only see the Novell server, while the filer thinks the Novell server is a Unix NIS server that also happens to be it's only client :o). Security is a subset of Novell permissions as available by mapping Unix permissions. The drawback here is that the Novell server itself will be an I/O bottleneck. 2) eDirectory and Windows integration. For this you need a DC, as you have identified. The Windows DC runs the Novell eDirectory client and the security is synchronised with Novell Account Manager. All clients that need to access the filer need to have the CIFS redirector running. Permissions are mapped by Novell Account Manager. An issue with approach 2 is that when passwords are changed by a helpdesk directly in eDirectory, they may not be synchronised immediately. If anyone has found a workaround for this please respond. regards, Alan. -----Original Message----- From: Robert Borowicz [mailto:rbaus@swbell.net] Sent: Wednesday, 16 April 2003 6:26 AM To: toasters(a)mathworks.com Subject: CIFS in Workgroup mode Does anybody run CIFS shares in workgroup mode?
