RE: SCSI on Filer 760 HVDS or LVDS
by Tom "Mad Dog" Yergeau 01 Dec '00

01 Dec '00

There is a tape drive compatibility matrix here http://now.netapp.com/NOW/knowledge/docs/olio/cert_matrices/tape_drives.shtm l which indicates that F700-series filers require HVD. As this article indicates http://now.netapp.com/Knowledgebase/solutionarea.asp?id=dfaf091a-9bbd-11d4-9 2f7-080020c8339b&resource=&number=19&isExternal=0 (link will be wrapped) you must use fast-wide differential SCSI drives and not single ended drives on an F700-series filer. The compatibility matrix indicates the F840 supports both FWD-HVD and LVD-SE, except for DLT7000 drives.

To correct one detail: > Also, the FilerView web admin program will allow password-less access from > any machine(s) listed in the "telnet.hosts" option. This poses the same > security concern if the machine(s) in "telnet.hosts" are compromised. The "telnet.hosts" option is only an "access" control. You still have to be authenticated after passing this access control. In ONTAP 6.0, FilerView uses HTTP basic authentication for everything (prior to ONTAP 6.0 it also used some rsh). ...Tim Thompson...Network Appliance, Inc...tjt(a)netapp.com...

Filer ATM card driver questions
by Joe Luchtenberg 01 Dec '00

01 Dec '00

I apologize for getting a little bit off topic... (I doubt many of you are terribly interested in pre-sales issues) Since so many NetApp personnel monitor this discussion list, could someone respond with who would be the best POC for me to call with a laundry list of specific detailed technical questions regarding ATM card drivers and support that is holding up a purchase request for a new filer. Pre-sales SE's are unavailable at this time, and I'd like to close this up today, if possible. TIA. Joe Joe Luchtenberg Dataline, Inc. New number and email, please update: 757.858.0600 858.0606 fax joe.luchtenberg(a)data-line.com

quota overhead
by Igor Schein 01 Dec '00

01 Dec '00

Hi, I'm thinking to implement quotas on the filer, but the one thing which concerns me is NFS performance. Can any1 try to quantify quota system's degradation effect on NFS performance? Please elaborate as much as you can. Thanks in advance. Igor

Security Question
by Villa, Tony 01 Dec '00

01 Dec '00

I had a question for this group. My company just started to install Filers on our network and I was wandering if there are any products that you use to connect to the Filer to replace the standard telnet command. I know Network Appliance sells SecureAdmin but I was wandering if there are any others out there. Our security group is concerned about using telnet since any passwords that is send is send in clear text. Any suggestions are welcome also if SecureAdmin is being used any input on it would be appreciated.

snapmirror bug
by Moshe Linzer 30 Nov '00

30 Nov '00

Hi, we are running snapmirror here to move a 350GB volume from our F630 to our new F760. Since we set it up last week, I have noticed a 'bug' in the snapmirror procedure: We set up the 2 volumes with the same amount of raw space. However, the source volume had a snap reserve of 5%, so we changed to target volume to snap reserve of 5% before taking it offline. We started the snapmirror, and the volume filled up to 103%. I checked, and the snap reserve had been reset to 20%, thus reducing the free space on the target volume, and preventing the mirror from completing. I made the volume writable, and tried to reset the snap reserve to 5%, but the same thing happened. I only succeeded in completing the mirror by adding a disk to the target volume, thus allowing enough space, even with a snap reserve of 20%. This sounds like a bug - why should snap reserve be reset on the target volume? Has anyone heard of this before? Thanks, Moshe

: My guess is that an : SSL-enabled FilerView, if ever created, would be packaged : with ssh in the SecureAdmin license. SSL-enabled FilerView is part of ONTAP 6.0. Once you've installed SecureAdmin 2.1, the initial na_admin page includes a link to Secure FilerView. - Brian

Dunno if it's just me, but the last two emails, one from Tom "Mad Dog" Yergeau and the other from Premanshu Jain, both arrived empty. Bruce

Either use SecureAdmin or get a secure terminalserver (like, for instance, a Linux box that you ssh into) and plug it into the toaster's console port. -- Leif Nixon Sysadm/developer Ericsson SoftLab AB ---------------------------------------------------------- E-mail: nixon(a)softlab.ericsson.se Phone: +46 13 23 57 61 ----------------------------------------------------------
