My F820 is slow ....
by Pawel Rogocz 31 Oct '02

31 Oct '02

I run 6.2.1 on F820 and I have bunch of Sun boxes ( around 60 ) who do NFS mounts. The filer has more than one volume and sometimes during the day the output of systat -x shows 100% disk util for a couple of minutes. 1. Is there a way to find out which volume/disk is causing bottleneck ? 2. Is there a way to find which client is causing the load to spike ? 3. Can disk util be monitored via SNMP ? I was not able to find anything in the MIB provided on NOW. thanks, Pawel --

Pawel, Have you grown your volumes lately? If so, how many disks did you add to the volumes when you grew them? I have seen customers who have volumes that are at 90%-95% and they add one or two disks to increase the disk space for the volume. What this does is creates a hot spot where any new writes going to those volumes only gets written to the 1 or two disks which were added = bad performance because WAFL is not able to stripe across all the disks in the volume.

optimum setting for Solaris8 and nfs/netapps
by Daniel Finn 30 Oct '02

30 Oct '02

What are the best options to use when trying to get the best performance and good stability out of a Solaris8 server mounting volumes via nfs from a F740/F760? Thanks Dan I've already made sure that the network connection for the Solaris server is 100MB fdx.

If what you're looking to do is make it forget that it's part of a cluster, you can try the following (which worked for us on some 760c's - I've never used/seen a 600 series though). At the ok prompt, do unsetenv partner-sysid Davin.

NetApp NDMP backup session benchmarks
by Broughton, Paul PM SITI-IT-DIETS 30 Oct '02

30 Oct '02

Fellow Members, We are looking at upgrading our backup environment having added a couple of NetApps F880 filers with +/-10TB of data recently. We already have a SAN storage island, so are looking at SAN attaching a STK L700E jukebox (housing either LTO drives or possibly 9940B drives), and linking the NetApp filers to the SAN also, thus allowing us to associate drives with Filers as needed. Initially, we then expect to use Legato to control NDMP sessions to enable the dump of the NetApp volumes to tape. My question is whether their are other Networkers who have similar conceptual solutions who can give an idea of the read/write throughputs we could expect for a single NDMP session, and what limitations/drawbacks there are when using NDMP. Any experiences welcomed, Best regards, Paul Broughton Email: paul.broughton(a)shell.com Internet: http://www.shell.com

Hello - new (old) F630 owner
by Dan O'Brien 29 Oct '02

29 Oct '02

We recently became caretaker of a new to us F630. This unit has 6 disk shelves, each shelf loaded with 9GB drives. We had NetApps come in and set it up (recertify it) after it was shipped to us from GB (we are in Ohio). Everything went fine except we had a couple of bad power supplies and a bad SCSI cable to one of the shelves. We are now looking at maintaining the hardware ourselves. We are planning on securing some spare parts and build a small hot spare system from which we can pull parts as needed. Anyone have any suggestions as new owners of a F630? We have lots of Unix and PC experience, but this is the first hands on with a NetApps. (BTW: why is NetApps so secretive with info on their web site? Docs, manuals, specs, are all highly guarded with logins, passwords, etc.) Cheers, Dan O'Brien, dmobrien(a)lcsi.net Cell: 614-783-4859 Work: 614-476-8473 Home: 740-927-2178 Pataskala, OH

RE: CIFS access slow
by Mike Ball 28 Oct '02

28 Oct '02

Simon, Did you change anything on your network recently? Are you doing auto negotiation on the Ethernet ports on the Netapp? If so, force them and the switch port to 100Mbit full duplex (unless you are using Gigabit Ethernet which you will leave as Auto negotiate). Run "ifstat -a" on the Netapp and see if you have excessive errors/collisions on a interface. Run tracert from the machines having slow access to the Netapp and see if they are going through any unusual hops.

RE: NBU 3.4 report tape drive status down occasionally caused bac kup to fail
by Conner, Neil 28 Oct '02

28 Oct '02

Check the All Log Entries report in NetBackup and syslog on the filer to find out why the tape drives are being downed - this should not be happening. You can't prevent NetBackup from downing drives, but you can change the number of errors that will cause a drive to be downed (3 by default). Search the KB on the Veritas web site for details. If it's not something you can easily solve, there is a script available called drivewatch.cmd which will you can add to the NT task scheduler to periodically check for downed drives and automatically "up" them again. http://www.xbpadm-commands.com/download.htm <http://www.xbpadm-commands.com/download.htm> Neil -----Original Message----- From: Alfred Lim [mailto:alf1650@hotmail.com] Sent: Monday, October 28, 2002 7:41 AM To: toasters(a)mathworks.com Subject: NBU 3.4 report tape drive status down occasionally caused backup to fail Hi everyone, Does any one ever encounter this before? We have 2 tape drives connected to 2 Network Appliance Filer. It goes down randomly every day and the following error msg is recorded in the application event log. We are running Veritas Netbackup Data Centre Ver 3.4.1 on Windows 2000 ? But when we "up" the drive in device monitor, the backup completes successfully. Does anyone know where to set on the filer or NBU to prevent the drive to go down?
