RE: DFM 3.0 issues
by Klaus.Micheler＠infineon.com 20 Jul '04

Hi Aaron, we also have SNMP Problems since we are using Ontap 6.5.1x. Problem is, that qtrees were not listed in our perl-coded filermonitor. Some qtrees on some of our filer were not listed over snmp-queries. - but Ontap command "quota report" works for all qtrees. Looks like its not a DFM Problem, but an(other) Ontap Problem. Please can you tell, if you know something new on that problem Another hint: DFM 3.0 and Ontap65-versions smaller than 6.5.1R1P8 lead to timeouts, because of an SNMP Bug in Ontap. Filer gets large timeouts when snmp-queries were running (BUG-ID:131280)! regards, Klaus -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Hill, Aaron Sent: Dienstag, 20.

Oracle on Filers
by Robert Borowicz 19 Jul '04

19 Jul '04

I may be asking the obvious here but who dedicates their Oracle->Filer traffic to just *one* Filer? IE: That Filer *ONLY* handles Oracle->NFS->Filer traffic. Our CIFS traffic has grown significantly since we bought our FAS940 and I'm now dubious about mixing CIFS/Desktop services with Enterprise critical Oracle services. Currently we have a few small DB's (read-only) on the Filer but are moving to step things up over the next year with Regards to Oracle. (we are looking at RAC). So: Would ALAWYS or SOMETIMES or NEVER mix Oracle and Desktop Filer services on one filer? :-) -Bob B.

RE: Oracle on Filers

Bob, It really depends on how much Oracle and CIFS traffic you have. That being said, the FAS940 is a very capable filer. On one of the FAS940C cluster we are serving Oracle on NFS for over 1200 users and also serving CIFS traffic for about that many users without any problem. The main issue for Oracle is the number of disk that you are using. Our Oracle database is sitting on 2 dedicated volumes of 13 drives each and we might be adding more disks there to help with the performance. You really need to collect detail statistics to help decide things like that.

Tool to manage filers
by Jason Storm 16 Jul '04

16 Jul '04

What tools to do you use to administer and manage your filer(s)? I am not the greatest fan of Filerview and was wondering how good is DataFabric Manager. Any other tools out there? Thanks in advance for your help. Filer Dude --------------------------------- Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start. We finish.

I believe what you are looking for is Filerview, built into the default features of ONTAP. http://<filername>\na_admin should get you started. Unless you are looking for something more specific. For that, I use perl, GUI's leave me feeling cold and unfulfilled :) Have fun.

RE: DFM database transfer
by Perry, Jay 16 Jul '04

Hi G, In your question, you didn't specify NFS or CIFS. Since I am *much* more comfortable with NFS, I wrote my answer in those terms, and hand waved outside of my comfort zone. In the case of windows, you are correct - you should use UNC paths. You'll also have to tell DFM the name of a CIFS account/password that can be used by the host agent to access the shares. This can be done on a per host agent basis from the Edit Agent Logins page (SRM tab -> Edit Agent Logins) or using a global default (go to the DFM options page, look under Host Agent Options, and configure the Host Agent CIFS Account and the Host Agent CIFS Password). If this doesn't help you, I would recommend that you work through your normal support channel, so that you can get feedback from folks that are more familiar with this specific DFM feature.

How do I "mount" a CIFS share on the windows system running the agent? Do you mean "map a network drive"? But for that a user needs to be logged in, correct?. Can we use an UNC path? We have a FAS 960 with 148 shares (Qtrees).

Simple Concise Filer Monitoring
by Ben Rockwood 16 Jul '04

16 Jul '04

Has anyone created a simple and readable web monitoring application for Filers? Sure there's Cricket, MRTG, and RRDtool, but I'd like something alittle more tidy for quick glances. I'd love something like phpSysInfo: http://phpsysinfo.sourceforge.net/ It seems like leveraging PHP or PERL CGI, with alittle RRD possiblably tossed in we could have a tool vastly superior to the aging "Filer At-A-Glance", which relies on Java (yuck) and doesn't supply everything in one nice page. Has anyone done something like this or feel it's a worthwhile cause? benr.
