DOT 6.2.2 - ndmpcopy
by George Kahler 01 Oct '03

01 Oct '03

When I try to run ndmpcopy from one of my filers' (840s) console prompt, it locks up and does not release the console until after it is done not allowing me to type anything else in. I realize that I can run ndmpcopy from any other hosts I'm just wondering if this is the correct behavior.

Wrapping pktt trace?
by Edward Hibbert (eh＠dataconnection.com) 01 Oct '03

01 Oct '03

To catch an application problem, I want to leave pktt trace running on a filer...overnight. If I do, it'll fill it up. I know you can tell it to bound the amount of space it uses, but I think it stops tracing once it hits that. Is there any way to get it to keep tracing within a bounded amount of disk space, just overwriting old trace files? That way I would have the last few hours of trace.

Attaching 4700 to an FAS940
by Robert Borowicz 01 Oct '03

01 Oct '03

I'm coming in on Sunday to cable two Sun L280 (4700?) DLT 7000 7 tape stackers to my FAS940. Support told me that the system will probe the SCSI controller and yield the correct device types. Here's my sysconfig -v output: slot 8: SCSI Host Adapter 8a (Adaptec AIC7899A) HW Version 0.0 Ultra160 SCSI, Low Voltage Differential slot 8: SCSI Host Adapter 8b (Adaptec AIC7899A) HW Version 0.0 Ultra160 SCSI, Low Voltage Differential Anything I should know to get these bad boys to work? I'll be configuring them as NDMP devices from my Legato 6.1.3 server next week. Thanks in advance! -Rob

Michel/Sto Rage, Here is what I monitor in Nagios for a F820 (please feel free to comment or suggest more ideas for monitoirng via Nagios/MRTG) (also, your NetApp appliance might be different than mine) - connectivity - telnet - CPU load $USER1$/check_snmp -H $HOSTADDRESS$ -C YOURCOMMUNITYHERE -o .enterprises.789.1.2.1.3.0 -w 90 -c 95 -u '%' - temperature $USER1$/check_snmp -H $HOSTADDRESS$ -C YOURCOMMUNITYHERE -o .enterprises.789.1.2.4.1.0 -c 1 - Disk Space $USER1$/check_snmp -H $HOSTADDRESS$ -C YOURCOMMUNITYHERE -o .enterprises.789.1.5.4.1.5.$ARG1$,.enterprises.789.1.5.4.1.6.$ARG1$ -w $ARG2$:,:95 -c $ARG3$:,:97 -u 'kB free (','% used)' -l "Disk space" Where : $ARG1$ is the volume (ie 1 is Volume 0, 3 is Volume 1, 5 is volume 3) (keep in mind the snapshots) $ARG2$ and $ARG3$ are the warning/critical in kbytes That's about it.

But I found a problem with the disk usage, After I rebooted the filer, the SNMP disk indexes changed and my graphs got messed up. I had to correct the cfg files to put the right MIBs back.

Coming to Nagios monitoring, I too would be interested in knowing what others are doing to monitor the filers. Also I would like to get the soft quota threshold notifications be emailed to the user along with their quota report and some standard text message. Is anyone doing that for CIFS users? thanks in advance -G ----- Original Message ----- From: Michel <mailto:michel@geldenhuys.com> Geldenhuys To: toasters(a)mathworks.com Sent: Thursday, September 25, 2003 2:48 PM Subject: RE: filer-mrtg (filer.mrtg.tar.gz) Hi, I'm using MRTG to monitor network traffic, CPU usage, CIFS/NFS operations and volume usage (max bytes vs used bytes) Since I also use Nagios, could you tell me how you configured it to monitor your Filers ?

Re: Dump performance
by Michel GELDENHUYS 29 Sep '03

Hi Duncan, I think you'll not see difference between native dumps and NDMP. Indeed, NDMP can ben seen as some kind of "remote control", so using NDMP to make backup with a Filer actually implies using dump. So NDMP is, for its most part, a mean to control dump operation, plus, and that's the added value, getting a catalog of the files backed up to easily recover them. For further info regarding how to tune tape backup, see here : http://www.netapp.com/tech_library/3066.html#6.

What are people monitoring on their NetApps with mrtg? Just curios cause I only use MRTG to graph the network traffic. I did think about using it for CPU/disk space but I currently use Nagios for that. I am sure others on this list will have good uses for MRTG on their NetApps....anyone care to share?

Alternatives?
by Tuc 26 Sep '03

26 Sep '03

Hi, We currently have a customer with an F760 and 6 shelves of 36's, and an F720 with 6 shelves of 18's. We've had problems with both that of course should never have happened. About the only thing we came up with is another F760 with 6 shelves of 72's, vol copy to it, and then having the customer FTP to both to keep things in sync. This solution is a bit pricey for the customer. (About $47K) Has anyone looked at any of the IDE based solutions to replace a F760 class filer? We do about 4500 to 5K NFSops. Anyone had any other ideas? Thanks, Tuc/TTSG Internet Services, Inc.

C4.log?
by Gifford, Josh 26 Sep '03

26 Sep '03

Hello Toasters, In troubleshooting latency issues between our main site and a remote location, we have noticed a lot of traffic going to our filer and erroring out. Each machine in the remote location is trying to get to a file called \%username%\c4.log on a filer in our main site, but is unable to find it. Between all 20 users in this site, these events are occurring every minute or two. This traffic is coming from machines running Windows XP and 2000, some of the machines are in our active directory domain, some are in our NT 4.0 domain. I can't even find a single application outside of MS Office that they are all using. An example of the packet trace is provided below. Does anyone know what the c4.log is? Josh J.

Any news?

A while ago we had a debate on lisencing of NetApp software for non commercial/hobbyist use. We had a very promesing conclusion that the lisence system needed reviewing. I was wondering if there is any news regarding this? John
