Aggregate snapshots?
by Steve Losen 25 Apr '05

25 Apr '05

We just got a R200 and FAS960c and I immediately upgraded them from 6.5 to 7.0.0.1. I moved the root volume to a flex vol and destroyed the old root, so now I have one big aggregate that contains the root volume. I discovered the "df -A" command and was surprised to see that my aggregate has snap reserve space, a snap sched running, and five snapshots. This is independent of the snap reserve and sched of my root volume. What is the rationale behind aggregate snapshots? We don't have snapmirror licensed. Can you snapmirror them? Can you snaprestore them? I presume this mirrors (or restores) the entire aggregate. I doubt that you can access aggregate snapshots from a NFS or CIFs client, or can you? Can you somehow tease out volumes from an aggregate snapshot and NFS export them? Within an aggregate snapshot, do you have just the active volumes, or the volumes and all of their volume level snapshots as they existed at the time the aggregate snapshot was taken? Mind boggling. I am probably going to set the snap reserve on my aggregates to zero and turn off the snap sched and manage my snapshots at the volume level. Any reason to not do that? Using both aggregate and volume snapshots looks about the same as using a belt and suspenders to keep your pants up.

quad nic's supported in F840 ?
by Tavis Gustafson 21 Apr '05

21 Apr '05

Does anyone know which quad ethernet card work in the F840 series? So far I have only tried the Matrox brand. I know that the Zynx brand works in the F760's, but I don't know if they'll work in the F840's. Anybody know? -tavis

Drive burn-in tools.
by Maren S. Leizaola 21 Apr '05

21 Apr '05

Hi, We are currently looking for a nice drive burn in tool that will read-write and give the hard disks a good beating before we put them in production. This not Netapp specific but I just can't find anything. Before there was some great Free programs to do this, and somehow i can't find any...

In our house, I dropped MRTG last year, and I'm using Cacti instead (http://www.cacti.net) It works the same as MRTG under the wire, but is much easier to configure and manage. Let me guess, your network stats aren't correct on your GigE interfaces? Last time I looked, NetApp insists that SNMP v2c and v3 aren't mature enough for them to bother with. SNMP v1 only supports 32 bit variables, which overflow at about 115 Mbps. To get around that, NetApp provides high and low order 32 bit values for the network counters.

It has to do with how your permissions are setup on the xp machine. If you go to folder options and make sure that you check can not see hidden files or folders or hide protected system files you won't see the snapshot folder. Hope this helps.

I just discovered the same thing. I did a search on Microsoft's site and read KB Article 888603, which describes some registry edits that can 1) Disable the "Restore" button on the Previous Version Tab 2) Disable the "Previous Versions" tab I tried disabling the "Previous Versions" tab, rebooted and still could see the "Previous Versions" tab. I am continuing to look for a solution, but am interested if anyone else has worked with this issue and has a work around.

Quota-related fixes in ONTAP 7.x

19 Apr '05

The various quota-related problems in ONTAP 7.x that were being talked about on toasters last month have fixes according to NOW: 153377 quotas wrongly reverting to default on a "quota resize" supposed to be fixed in 7.0.0.1P4 154530 per-user/group quotas wrongly affecting the results of statvfs() supposed to be fixed in 7.0.0.1P5 Can anyone who has tried these ONTAP versions confirm the fixes? -- Chris Thompson Email: cet1(a)cam.ac.uk

File Sharing Windows <> NFS Volume on R150 (6.5.2R1) ...
by Doug Chomyn 18 Apr '05

18 Apr '05

Sorry if this a bit lame. Basically, I want to file share .xls documents stored on an NFS volume between Windows clients so that when one client with RW on the document has access, another Windows client can open the document R only, etc, etc. Ordinarily we would do a re-share via Samba, or perhaps make a CIFS volume share, but I'm trying to reduce complexity (and we're not going to buy a CIFS license) ... anyone have experience with doing this kind of thing? Is it possible? tx doug

Hi Robert, It's just the same as a normal reconstruction when a disk fails. The time depends on the disk size, filer and the value of your reconstruction speed (low, middle, high).

You cannot have more than one filer attached to the same SCSI chain. What you can do is have one drive attached to one filer and another drive attached to another filer, as long as you can break the SCSI bus at the library side. Most libraries with more than 2 drives can do this. You will see multiple in/out connections. That is what it is for. --tmac ====================== Tim McCarthy Professional Services/Systems Engineer NetApp Federal Systems, Inc. 410-551-3970 (o) 443-363-0208 (f) tmac(a)netapp.com tmac-pager(a)netapp.com ====================== -----Original Message----- From: Alan Sparks [mailto:asparks@doublesparks.net] Sent: Friday, April 15, 2005 11:00 AM To: Lance R Bailey Cc: Toasters List Subject: Re: Changing Netapp SCSI target ID Lance R Bailey said: > i have a qualstar library with the drives attached to a linux host, > F720, F87 and F85 filers. > > the scsi number is set on the library. each drive slot has a different > number. when the filer sees it (verify with sysconfig -t) the scsi > number assigned to the drive on the scsi bus will be the one on > library. OK. So you're saying that it will not cause a conflict if I daisy chain the filers together onto the same wire to the library drives. OK, that or 3-way NDMP are two possible options then.

Changing Netapp SCSI target ID
by Alan Sparks 15 Apr '05

15 Apr '05

Possibly a weird question, but... I need to connect a Qualstore library to my toasters (760 filers) by daisy-chaining them to the library. Just don't have the ports on the library to direct connect to the drives. But unless I really misunderstand, these filers will all have the same SCSI IDs, so there's gonna be a conflict. I need to let my NetBackup server control everything, and run NDMP on the filers to do the backups. Is there any way to retarget the SCSI ports built into the Netapp head to be on an ID of my choosing, so I can sidestep the ID conflict? Thanks in advance. -Alan -- Alan Sparks, UNIX/Linux Systems Integration and Administration <asparks(a)doublesparks.net>

mrtg config files
by Munn, Stuart 14 Apr '05

14 Apr '05

People, I've used the filer-mrtg scripts from Now in the past, but I'd prefer to go down the SNMP route, as I suspect the network stats are not working well on the later releases of ONTAP ... Has anyone got some mrtg config files they can share with me? I've tried using the search archive facility on the mathworks site but It's not much use as it does not sort in date order and you cannot see the whole of the subject! Any advice welcome... Cheers Stuart Munn SAIC Ltd
