RE: Ms Exchange and Netapp Filers

As per http://www.netapp.com/tech_library/3074.html MicrosoftR Exchange and NetAppT Filers: Recommendations for Deployment, if you scroll down to section 4.2.2, we highly encourage the use of low latency connections like Gigabit, particularly in database configurations. There are several other useful documents in the tech library that will steer you in the right direction for a successful deployment, including http://www.netapp.com/tech_library/3054.html MicrosoftR Exchange and NetAppR Filers: Technical Integration and Installation Supplement and http://www.netapp.com/tech_library/3067.html MicrosoftR Exchange and NetAppR Filers: An Overview. In addition, an independently-written Total Cost of Ownership report is at http://www.netapp.com/tech_library/3103.html.

RE: Deleting data on NetApp.

Rm is a very simple command with no switches. It will refuse to delete a directory. The syntax is rm <full path name> In general, deleting files from Unix or NT is preferable.

We have just added a new tool to the "Tools and Utilities" download area on the NOW site, for exactly this purpose. It is called the "Per-Volume Performance Stats Tool", written in Perl. You can either use it through a web interface (you install it behind a Windows or UNIX web server and talk to it through your browser) or use a CLI version that is also included. The URL for the tool is: http://now.netapp.com/NOW/download/tools/pvstats/ Please check it out, and we're certainly interested in any feedback on it - we intend to do more in the area of performance tools, and your input always has an effect. ...Tim Thompson...Network Appliance, Inc...

Netapp + Amanda.: Problems
by Ashwin Kotian 12 Jul '01

12 Jul '01

We have been having problems backing up our Netapp filer using Amanda. We are using the modified dump program for Netapp but still everytime the amanda script runs it finds the mounted disk offline. The following are the entries in our Tape Backup server running Amanda server( it hosts the tape device too )...../etc/fstab file: /dev/sda5 on / type ext2 (rw) none on /proc type proc (rw) /dev/sda1 on /boot type ext2 (rw) /dev/sdb1 on /SPOOL1 type ext2 (rw) /dev/sdc1 on /SPOOL2 type ext2 (rw) none on /dev/pts type devpts (rw,gid=5,mode=620) automount(pid468) on /misc type autofs (rw,fd=5,pgrp=468,minproto=2,maxproto=3) xxx.xxx.xxx.xxx:/vol/vol1/home/oracle/oradata on /netapp/oradata/backup type nfs (ro ,addr=xxx.xxx.xxx.xxx) xxx.xxx.xxx.xxx:/etc on /netapp/etc type nfs (ro,addr=xxx.xxx.xxx.xxx) (xxx.xxx.xxx.xxx is the IP address of our Filer Interface) Also, the entries in the disklist file corresponding to the Netapp Filer is: # BEGIN NETAPP SECTION # Netapp filesystems via modified dump program. xxx.navin.com /netapp/oradata/backup nocomp-user -1 local # END NETAPP SECTION where xxx.navin.com is the FQDN of our Tape Backup Server. I have the debug option ON during the Dump......and /tmp/dumpout gives the following log output for the Netapp filesystem: ---- [25044]: Mon Jul 9 19:02:01 2001 [25044]: dump 0Shsf 0 1048576 - xxx.xxx.xxx.xxx:/vol/vol1/home/oracle/oradata [25044]: xxx.xxx.xxx.xxx:/vol/vol1/home/oracle/oradata: No such file or directory while opening filesystem^M ---- [25047]: Mon Jul 9 19:02:03 2001 [25047]: dump 1Shsf 0 1048576 - xxx.xxx.xxx.xxx:/vol/vol1/home/oracle/oradata [25047]: DUMP: WARNING: There is no inferior level dump on this filesystem [25047]: DUMP: WARNING: Assuming a level 0 dump by default [25047]: xxx.xxx.xxx.xxx:/vol/vol1/home/oracle/oradata: No such file or directory while opening filesystem^M ---- Also, the /tmp/amanda/sendsize.debug contains the following entries: asking killpgrp to terminate calculating for amname '/netapp/oradata/backup', dirname '/netapp/oradata/backup' sendsize: getting size via dump for /netapp/oradata/backup level 0 sendsize: running "/sbin/dump 0Shsf 0 1048576 - xxx.xxx.xxx.xxx:/vol/vol1/home/or acle/oradata" running /usr/local/amanda/libexec/killpgrp xxx.xxx.xxx.xxx:/vol/vol1/home/oracle/oradata: No such file or directory while op ening filesystem^M .....

My answer today is sponsored by the NTAP Advanced ONTAP class. This class covers how to measure items like the ones suggested below. Check out the NOW site for times, places, and costs..it's worth it! Now to the answer: To view NVRAM stats, you use the wafl_susp command. To find this command, you'll need to be in rc_toggle_basic or priv set advanced mode. To zero out the stats, use: filer*> wafl_susp -z Then run your test. Then to view the stats, run: filer*> wafl_susp -w You'll get screens full of info but the really important ones are the following 3: cp_from_timer cp_from_log_full cp_from_cp The first 2 are good, the 3rd one is bad. cp_from_timer is the number of times your NVRAM was flushed because half of the NVRAM was not filled in 10 seconds. cp_from_log_full is when you filled up half of your NVRAM and flushed it before the 2nd half of your NVRAM filled. Again, not a big deal. The 3rd one, cp_from_cp means that you filled the 2nd side of your NVRAM BEFORE you finished flushing the first half. This is bad. It's okay to have a few of them, but if they get to be a signifcant percentage of your cps, you're either over-running your NVRAM, or there's a problem with your disk subsystem and it's not writing out the data very quickly (like maybe your volume is 99% full). Now individual disk utilizations are found with statit. This is similar to wafl_susp in that you start it, then you stop it and print out the results. The 2 command for statit are filer*> statit -b to start collecting filer*> statit -e to end it and dump the data. You'll find how busy your individual disks are that way, plus a BUNCH of other things, but that's probably the most important. But before I'd even go down these paths, I'd be watching my sysstat's very carefully. sysstat 1 is your friend in looking at performance. It can give you some really good clues. Also check netstat, ifstat, and the other networking commands for errors. Check your switch ports for dropped packets. Things like flow control settings (a good thing, I suggest full flowcontrol on send and receive) can also mess up Gbit interfaces. Anyway, this is probably all I can practically jam into a single message and have it make sense. Of course, the Global Support Centers at NTAP are always here and can help your diagnose these types of problems as well. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Flavio E.

I would doubt there were any big fixes to spares_zero. I haven't checked them, but since it's not in regular command mode, I wouldn't hold my breath. One way to keep your console while the process is running is to issue the command via rsh from a trusted host. That way you don't chew up your prompt. Something like: # rsh filer 'priv set diag ; spares_zero' Note, use the single quotes so that both commands go to the filer.

spares_zero still exists, but you need to set your privledge move to diag rather than advanced. This is supposed to all be fixed in an upcoming release and there will be an officially blessed way to do this. Stay tuned.

Hi Srs. I´m looking for benchmark infomation about FILER 760, mainly about NVRAM and disk´s operations (reading and writing). We´ve got the Filer and Servers on a Gigaethernet network but when we see on switch statistics the thoughtput is slowly than a fastethernet. Flavio Cardoso

benchmarks
by Steve Sapovits 12 Jul '01

12 Jul '01

I'm looking for any benchmarking info. related using a NetApp instead of server-dedicated disk in a web server cluster; i.e., how many web servers can I run before a single NetApp device becomes slower than using dedicated disk per server? The more specific the benchmarks, the better (relating to types/versions of servers, OS, etc.). ---- Steve Sapovits
