RE: ndmpd status
by Melvin, Grant 20 Aug '99

20 Aug '99

Hi Graham, This is resolved in Data ONTAP 5.3 and higher. ndmpd is rsh'able. In Data ONTAP 5.3 we ported the NDMP server to the JVM on the filer. One of the reasons to allow more than 5 NDMP concurrent sessions. We have now set an arbitary limit of 1000. Cheers, Grant -----Original Message----- From: Graham Knight [mailto:grahamk@ast.lmco.com] Sent: Friday, August 20, 1999 11:10 AM To: toasters(a)mathworks.com Subject: ndmpd status I was quite suprised that you cannot do a "rsh toaster ndmpd status". Does anyone know of any tricks to get the status of ndmpd connections from a Unix shell? I want to make sure connections are available before i launch ndmpcopy processes. Along the same lines - is it possible to increase the amount of concurrent ndmp sessions beyond the default of 5? Thanks, Graham

tech support waits
by Todd C. Merrill 19 Aug '99

19 Aug '99

I am getting frustrated with the response time from tech support. The engineers who take the calls are not responding to my requests for status updates, for days even. Not even a peep, such as, "We're still working on it." I have not tried the "comments" section from the call log on NOW, but I don't have faith in that if supposed *direct* communication to the engineer isn't working. I have started calling the 888-4NETAPP number, and waiting on hold for 20-30+ minutes. There is no way to quickly just say, "Have the engineer call me, *please*"; you have to wait...and wait....and wait.... I waited over 20 minutes the other day. Frustrated, I hung up, redialed, and entered the option for "the filer is not serving data," hoping I could get someone quickly. Hah. 18 minutes later someone answered the call. I asked the engineer if today was a busy day; the reply was, "Not really." I don't know about other people, but if this had been an actual emergency and our filer was down, waiting 20 minutes is unacceptable. There were threads a while back about response and wait times. Are others still experiencing these interminable delays? In defense of NetApp, though, I did make a call at 6 AM (EDT) last Friday, and got someone immediately from their third-shift in Europe. Yea! That is much improved! (Now, if I could only get a hold of that engineer *again*...) Until next time...

RE: HELP TO DECIDED THE ONTAP VERSION TO USE WITH BUDTOOL
by Melvin, Grant 13 Aug '99

Hi Alex, I received good news last night that BudTool 4.6.1 is now certified with Data ONTAP 5.2.3: NetApp Release 5.2.3 has been tested, and certified with BudTool 4.6.1. Local, Remote, and 3 party configurations were tested. Legato havn't updated their external web page yet at: http://www.iguard.com/products/certmatrix.html since the product marketing manager is out today. It should be updated next week sometime. Legato will be certifying 5.3.2D1 next. Cheers, Grant P.S. We have moved our internal version of the NetApp/VERITAS (NetBackup) software certification matrix to: http://now.netapp.com/knowledge/contents/TIP/TIP_605.shtml These URLs should provide you with the information that you require. -----Original Message----- From: Alexandre Gomes [mailto:r7043c@email.sps.mot.com] Sent: Friday, August 13, 1999 10:58 AM To: toasters(a)mathworks.com Subject: HELP TO DECIDED THE ONTAP VERSION TO USE WITH BUDTOOL Hello, Could some one help me decided what version of Network appliance ONTAP is compatible with budtool version 4.5 and 4.6.

There will continue to be a far larger installed set of applications that use only NAS and not SAN. In fact, very few applications use *only* SAN directly, because that would largely be useless; the data still has to get to the end-user to be useful, even if it's through a secondary application, and that user is very likely to be connected over a network.

I'd like to second the recommendation of lsof, which is essentially the second incarnation of the ofiles command. I did some work on it for Vic as an undergrad. As the the locking issue, I had always found simply restarting lockd and statd on the client were sufficient, without the procedure of locking another file in-between. But perhaps it depends on the client and the filer OS version. Bruce

The Promise Of SAN ???.....EMC answer....

Here is EMC answer...Regards, Patrice ------- Forwarded Message Follows ------- From: "blumenau, steven" <blumenau_steven(a)emc.com> To: "'tzelnic(a)emc.com'" <tzelnic(a)emc.com> Copies to: "ofer, erez" <erez(a)emc.com> Subject: RE: (Fwd) FW: The Promise Of SAN ???..... Date sent: Thu, 12 Aug 1999 12:24:17 -0400 Percy, No company left the FibreAlliance. This was a mis-interpretation of only one reporter. Note that no other press reported the same story. The FibreAlliance is focused on managing SANs. The OSFI is focused on working on interoperability of the protocol for switches. Specifically, how do two different vendors switches talk to each other over eports. All the work that the FibreAlliance does is submitted to standards bodies (ANSI, IETF, DMTF, etc). So there is no reason that they can be considered proprietary. For example, the MIB is currently a proposed draft in IETF and changes to the protocols have been submitted to ANSI. The quote below from Roger (Reich) was mis-quoted out of context. Roger even sent in a letter to unigram about this and it was published. As to all the groups working on standards, it turns out that we are all working together very well. The FibreAlliance is focused on SAN management at the lower levels of protocols, APIs and MIBs. It turns out the SNIA has adopted the MIB that we submitted to IETF and have proposed changes which have been incorporated into it. Finally, I have seen lots of presentations by analysts about NAS and SAN and what is stated below is really focused on the point they make of where do NAS and SAN meet. If you need to have file sharing, then use NAS but even the NAS server will need the benefits of SAN (connectivity, distance, scaleability, etc). So the analysts position NAS as using SAN on their backend. There are still, and will continue to be, a large installed set of application that do not use NAS and they will use SAN directly.

Thanks, this gets me a little closer. What you write below leads me to believe that I need to grovel around in statd source (or sniff the wire) to find our just what it is sending at this moment. "Keith Brown" <keith(a)netapp.com> writes: > 4. Restart statd. Statd will send a STATMON packet to the filer > that causes the filer to blow away all of the locks for that > client. Here's another quick tip for folks: Vic Abell, the author of the o-so-useful lsof program (which knows about locks in some cases), also has a program called lslk for listing existing locks. Both lsof and lslk can be found at <ftp://vic.cc.purdue.edu:/pub/tools/unix/>. I've communicated with Mr. Abell, and he does not know of any specific tool to do what we've been discussing.

NFS lock tools
by dnb＠ccs.neu.edu 13 Aug '99

13 Aug '99

Howdy- I have a quick question which is marginally connected to NetApp-land. I was wondering if anyone had a tool for spoofing the RPC call(s) necessary to tell an NFS server to let go of a lock. Barring that, any pointers (besides OS source, which is my next stop) to documentation of the necessary dance would also be appreciated. I'd like to deal with the cases where a server thinks a file is locked, but the client has forgotten all about it (in a more graceful way than changing the file's inode by moving the data to another new file and then back again). I'm guessing the folks in NetApp engineering must have a lock make/break tool handy for their regression testing, hence my request here. I'd also be interested in knowing if there are any magic OnTap commands for showing all of the exisiting locks that the box is holding. Thanks! Respectfully, David N. Blank-Edelman Director of Technology College of Computer Science Northeastern University
