Multistore/vfiler experiences?
by Brian Tao 30 Apr '02

30 Apr '02

Does anyone have any real-world experience with vfilers (the "MultiStore" capability in 6.2) they can share? I have an opportunity to consolidate a bunch of older F740s onto a pair of clustered F840s, but I'm not sure about putting all my eggs (well, half my eggs) into one basket. It isn't quite possible to get 100% availability with Netapps yet, and it's been nice in the past having a handful of discrete clustered F740 systems for limiting the effect of downtime. The vfiler stuff looks intriguing, though... -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

I did a survey for NetApps and got an email from Amazon saying I had a gift certificate but it was blank. Anybody else run into this? Remember, you are unique... just like everyone else! Paul Maglinger, A+, CA, CET, MCSE Systems Administrator Shoe Carnival Inc. (812)867-4674 pmaglinger(a)scvl.com

Filer Storage Charge Back?
by Infantino, Vincent (Exchange) 30 Apr '02

30 Apr '02

Are there any good utilities (other than quota reports) that NetApp provides or any recommended 3rd Party application that can be used to create a monthly charge back report based on storage allocated to a particular user?

Filer takeover
by Jose Celestino 30 Apr '02

30 Apr '02

Hello, I fail to understand the following sentence: "When you configure virtual interfaces for takeover, you must specify the interface name and not the IP address." I have one vif in each filer, separate ones, trunk1=192.168.1.103 on 1st filer and trunk1=192.168.1.104 on 2nd filer. Does the previous sentence mean I have to put: ifconfig trunk1 192.168.1.103 mediatype 100tx-fd partner trunk1 ? That doesn't make much sense. Tried also ifconfig trunk1 192.168.1.103 mediatype 100tx-fd partner 192.168.1.104 but keep getting partner 192.168.1.104 (not in use).

RE: Tape drive recommendations

*** Before acting on this e-mail or opening any attachment you are advised to read the disclaimer at the end of this e-mail *** Whilst it's not here yet, decision making should allow for O-MASS technology that should be out (first generation) in 2003. This is a step change that I've been waiting about 18 months for * tape is much shorter therefore read times much faster * silicon head gives much closer tracks (and is less susceptible to alignment errors due to heat expansion) * tape is native 600GB capacity * 64MB per second transfer * third generation product is predicted at 2.4TB per tape, and 256MB per second <g> Obviously still to get here, but if (like me) you have a large DLT platform and were thinking of using SDLT as a compatible upgrade, it might be worth hanging on with DLT8000 drives, and change to O-MASS in a year or two.

The battle of the tape format is continuing day by day. Many vendors are pushing people away from current DLT technology saying it's doomed, and that AIT isn't far behind.

Simply centrally logging events, using a log-parsing tool such as Swatch, and then appplying appropriate filtering rules over time results in a pretty decent signal-noise ratio of "significant" events that merit watching. You still need some other stuff (ex: simple remote monitoring via ping/CIFS/NFS functionality), and doesn't help you too much in the performance area, but syslog is good stuff IMHO. alek P.S. Here's a presentation on using Swatch: http://www.komar.org/ -> Misc. Tech Stuff -> Swatch

RE: Backups to 6 tapes failing

Do you have mutliplexing turned on or off? Off is probly best. And when you say "slot" I assume you actually me drive? Or do you have a robot with only 1 drive and 7 tapes?

We are using Veritas Netbackup Datacenter to backup a filer running 5.3R2 to a DLT 4700 7 slot device. I am seeing a backup on one volume to 3 tapes working fine, but a backup to more than 4 tapes seems to fail. The backup runs and selects tape 6, tape 5, tape 4 and tape 1, missing tapes 3 & 2. It will then time out and error saying cannot allocate new media. Has anyone else seen this behaviour?

Request for Input on Independant Filer tools
by Ben Rockwood 25 Apr '02

25 Apr '02

Hello Mighty Toasters, As some may have noticed recently, I've become very interested in monitoring tool development for the filers. I've recently had a minor breakthrough using SNMP tables and mutli-dimensional arrays in PERL. This is particularly interesting because it gives me the ability to develope tools that can run sorts on the raid tables, disk usage tables, and more. Here's the problem, most of the tools I'm building now have little to no value. They are amusing and fun to write, but especially if you use FilerView these tools are useless. While this is a credit to NetApp, I'm curious if there are any tools people would like to see. What types of monitoring tools would you guys like to see? Performance tools are pretty well taken care of with MRTG and Cricket, though it would be fairly simple to use an snmp polling loop to drop files into either a MySQL/PostGreSQL backend or maybe just a BerkleyDB and then run GNUplot on 'em for a more simplified Cricket replacement, but since Cricket is so trusted it's unlikely for any of my tools be replace it. In essence, I've solved the problems I need to solve and now what to find some way to use all the kool tricks I've learned in the proccess. Ideas? If nothing else, I'm hoping to write an article soon about how to easily develop your own in-house tools for the Filers, which is probly the most useful thing I could do. Thanx in advance.

Quantum/ATL P14000, gigabit Ethernet sdlt -- anyone else using this?
by Quentin Fennessy 25 Apr '02

25 Apr '02

We recently purchased a Quantum/ATL P14000 (2xP7000), configured with Gigabit Ethernet sdlt tape drives on a Cisco switch. We are using Workstation Solutions QuickRestore, version 2.7.10. We're trying to backup Netapps (F760s, 840s, 880s) via a Solaris QR host. Unsuccessfully. Is anyone else using the P7000 or P14000 changer? With Gig SDLT? With QR? Our challenges are legion. Are we alone? I'd like to correspond with or talk with someone who has made this configuration work. Thanks -- Quentin Fennessy Quentin.Fennessy(a)amd.com Office: 512.602.3873 Cell: 512.694.7489
