In addition, Network Associates'(McAfee) NetShield for NetApp v4.5 also works with Data ONTAP. -----Original Message----- From: Simeone, David [mailto:David.Simeone@netapp.com] Sent: Friday, October 26, 2001 8:07 AM To: 'Ziller, Frank'; Strange, John Cc: toasters (E-mail) Subject: RE: Virus Scanning?

RE: Upgrade from F740 to F840
by Jay Newton 26 Oct '01

26 Oct '01

It's pretty easy. Go ahead and download the version of OnTap you want to use (Intel of course). Grab the disks and make them, too. Extract the new OnTap (Intel) to the 740 that's in place using the standard OnTap upgrade procedure. Down the original 740 and swap heads. Boot with floppies on the 840. When normal boot is complete, log in and run "download" command. Reboot again without the floppies and it should be good to go. Did this 2 months ago. Went smooth as glass. -----Original Message----- From: Uros Lampret [mailto:uros.lampret@ourspace.si] Sent: Friday, October 26, 2001 7:06 AM To: toasters(a)mathworks.com Subject: Upgrade from F740 to F840 Hi! I intend to upgrade from F740 to F840. I will only swap heads and keep the disks. I can't seem to find document describing this procedure. Any body done that?

Etherchannel vs. Jumbo Frames
by jwitham＠takedapharm.com 25 Oct '01

25 Oct '01

Hi all: Firing up my new F880 and have a question about gigabit Ethernet throughput: Currently, we vif multi our filers to our Catalyst 6509 switches using Cisco Gigabit EtherChannel with 1500 MTU I went to fire up the 880 today, and decided new filer, new UNIX boxes, let's use Jumbo Frames! (9000 MTU). Looks like you can't EtherChannel Jumbo frame ports. I'm wondering if anyone has done a comparison (formal or informal) between Gig EtherChannel and Jumbo Frames. If so, which was faster? I'm fine single vif'ing the 2 gig-E nics to different switches if that will perform better than the lower MTU port channeling. Thanks! -john

F720 CPU Maxing out
by Jean-Christophe Smith 25 Oct '01

25 Oct '01

We have a NetApp F720 doing both NFS and CIFS using mixed mode security. It has 256 megs of ram. During parts of the day the CPU and RAM spike to %100 utilization. We do a lot of sendmail, windows media, apache and IIS traffic over the filer. I have two questions: 1. Is there a way we can add more ram, perhaps 512 or a gig? The docs say we are maxxed out with 256. 2. Is it possible that the extra cpu overhead that provides the NFS/CIFS user mapping is causing much of the ram and cpu starvation? Perhaps going to a simpler security model would offload a lot of CPU cycles. Any suggestions would be appreciated.. Jean-Christophe Smith VitalStream jsmith(a)vitalstream.com

RE: Veritas Netbackup Database
by Strange, John 25 Oct '01

25 Oct '01

Hmm, I would say that file locking has improved, if you want to test that setup a mail server on the NFS mount and generate a lot of emails, or database of some type to test it. Where I would be concerned would be in the middle of the back to have a network problem and end up trashing the backup database. I would really be hard pressed to use NFS to store the backup database. If you plan on doing it make sure you are forcing sync on your NFS mount also as NFS v2 usually defaults to async writes. Which could cause a consistency problem if you suffer a network outage. Also another concern would be that your backup would probably fail if you hang the NFS mount as most *NIX boxes hate when you lose network connectivity across an active NFS mount. - John -----Original Message----- From: Manny Kaiser [mailto:mkaiser@mmcnet.com] Sent: Thursday, October 25, 2001 3:28 AM To: Jon Walton Cc: toasters@mathworks. com Subject: RE: Veritas Netbackup Database I was under the distinct impression that file locking in NFS in today's operating systems is considerably more reliable then it was years ago. I have never encountered a problem with any application running on an NFS mounted file system. I am under the impression that the quote below is something that was copied out of earlier versions of the manual and never reviewed again. When using NFS you might suffer a performance penalty if your systems are not correctly configured. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Jon Walton Sent: Wednesday, October 24, 2001 11:31 PM To: Jeff Kennedy Cc: toasters@mathworks. com Subject: RE: Veritas Netbackup Database Now that I look, the 3.4 DataCenter install guide states: "Because the product uses file locking, VERITAS recommends that you not install NetBackup in an NFS mounted directory.

Veritas does officially support putting /usr/openv onto an NFS file system. However, they say that performance does suffer due to the large write streams. So, if performance is not an issue then it is a very nice solution. Also, db backups do not yet support disk storage unit backups. Supposedly in 4.5 they will for just this reason. ~JK Jon Walton wrote: > > I believe they do not support this due the fact that operations on the > database files involve file locking.

carrierscan
by Tim Longo 25 Oct '01

25 Oct '01

Greetings: I am preparing to install Symantec CarrierScan, and came across something in the manual I have a question about. There is a statement in the manual that says "Virus scanning should be disabled before initiating backup of the NetApp Filer". It seems to me that this may not apply if ndmp were being used for backup? Anyone else have experience with this issue? Thanks, Tim
