F760 SCSI, Single-ended or Differential
by Harold White 09 Dec '03

09 Dec '03

Greetings, I just noticed that my F760 displays, what I believe to be, its on-board external SCSI port as "Fast/Wide, Single-ended" F760> sysconfig -v NetApp Release 6.4R1: Thu Mar 13 22:59:45 PST 2003 .... slot 0: SCSI Host Adapter 0b (Qlogic ISP 1040B, <ONLINE>) Fast/Wide, Single-ended Firmware Version 4.66.00 Clock Rate 60MHz. 4: Tape: Quantum DLT7000 245F 5: Tape: Quantum DLT7000 245F ..... I am/was under the impression that it was a Fast/Wide Differential (on-board) SCSI controller. I have 2 DLT7000 drives connected to the Filer ... and they are absolutely differential (2 drives from a Sun L1000). My Veritas Datacenter software keeps down'ing one of my drives and I have just ignored it due to time constraints plus the fact that I had/have one good drive still working. But now that I am trying to troubleshoot the problem, I do not know if the problem is that I have been lucky that a "Single-ended" filer controller has been providing me good backups to my differential (one) tape drive? (Is that even supposed to work at all?) Can anyone confirm that the output (sysconfig -v) of a F760 "Single-ended" is correct or incorrect? That is, is the on-board external SCSI port a differential or single-ended SCSI port and the "sysconfig -v" message is right or wrong? Regards, Harold White Covaro Networks

Re: F760 SCSI, Single-ended or Differential
by Graydon Dodson 05 Dec '03

I once had to RMA the motherboard on an old 760. After the swap the onboard SCSI changed from single-ended to differential. Since I was not using the motherboard SCSI it was not an issue for me. I now have two 760s one reports motherboard SCSI as single-ended and the other differential. I suspect there are two different motherboard designs for the 760. Graydon Dodson

AW: clustered filers and CIFS ...
by Engmann, Tobias 05 Dec '03

05 Dec '03

You can do it,you must ensure cross network connectivity. If filer A fails,filer B will completely taken over Filer A including Network and Netbios Identity etc.so you have one physikal and one virtual Filer in the same physikal Network Segment. Regards, Tobias Engmann SE Netapp Cluster characteristics The filers in a cluster have the following characteristics: * They are connected to each other through a cluster interconnect consisting of adapters and cable through which they * Continually check whether the other filer is functioning * Mirror log data for each other's NVRAM * Synchronize each other's time * They use two Fibre Channel Arbitrated Loops (FC-AL), in which * Each filer uses the A loop to manage its own disks * Each filer uses the B loop in takeover mode to manage its partner's disks * They own their spare disks and do not share them with the other filer. * They may reside on the same NT domain or on different domains. -----Ursprüngliche Nachricht----- Von: Waters, G Scott STG [mailto:george.scott.waters@us.army.mil] Gesendet: Donnerstag, 4.

Kerry, 6.4.2P11 is a GA release. Take a look at the the Data Ontap Release Model http://now.netapp.com/NOW/products/ontap_releasemodel/. 6.4.2P6 is a GA release, and was released as GA in September.

Hi Prashant- I train new sales people at NetApp. My favorite book for an introduction to storage networking is "Using NAS and SAN" by W. Curtis Peterson (published by O'Reilly). This has been required reading for our sales force. A thicker read but also good is "Building Storage Networks" by Marc Farley.

syslog, swatch/logsurfer, and you
by Peter 03 Dec '03

03 Dec '03

Hello toasters, I've been thinking of doing some additional monitoring of my filers using swatch or logsurfer. I am currently looking at transcribing what docs I could find on the NOW site to swatch or logsurfer regex, but thought it might be a good idea to see if someone has done this already and would care to share any info with me. I've also looked around the NOW site for actual examples of syslog entries that the filers will generate when something bad has happened, but was unsuccessful in finding anything. Has anyone located or compiled such a list? I googled, searched the toasters archives, etc. No luck. Anyway, let me know if you have anything interesting to share! Thanks, Peter Radavich

Default units for quotas in 6.4.2P6
by Chris Thompson 02 Dec '03

02 Dec '03

We have just upgraded from 6.3.3 to 6.4.2P6 (now it is "GA") and suffered a nasty consequence. If an entry in /etc/quotas doesn't specify any of "K", "M" or "G" for the limit, e.g. 261 user@/home 81920 4000 then the units are taken to be bytes rather than (as before, since time immemorial) kilobytes. In the example the limit becomes 80 KB rather than 80 MB. We have a daily useradmin job that runs overnight, and among other things builds a new /etc/quotas from another data source and then does a "quota resize". Our users weren't too happy to have all their quotas divided by 1024 in one swell foop... I have added an explicit "K" now, of course. All the documentation I can find still claims that "The default for the disk limits and warning threshold is kilobytes", so maybe this is a bug. Or maybe it will be reclassified as a feature when NetApp get around to updating the documentation. Anyway, it's something anyone upgrading ought to beware of. Chris Thompson Email: cet1(a)cam.ac.uk

Large directory performance bug? F760/6.1.2R3/Linux/2.4.20
by Chris Miles 01 Dec '03

01 Dec '03

Hi, we have over 20 webservers running a web application and serving all the data off a Netapp NFS mount. Netapp CPU normally sits at around 20-40% and NFS response is good. Today we hit what appears to have been a bug of some sort. All of a sudden, with no apparent increase in client connections, the F760 CPU went to 80-90% and the load on all the webservers rose sharply (from approx 0.5-1.5 up to 15-20). The site response went down the drain (20+ seconds for a page that normally takes under 1 second). It appeared to be caused by the application doing readdirs (along with other operations: read/write/getattr) on a specific directory, which at that time held about 70,000 files. We fixed the problem by disabling the readdirs within the application and also reducing the number of files in that directory down to about 45,000. We don't know exactly which fix (stopping readdirs or removing the files) did the trick, but after that Netapp CPU dropped back to normal and the webservers were happy and the site responsive again. It appeared that the combination of all the operations on the large directory were causing the NFS clients to hang and the Netapp CPU to max out. Although at the same time, other NFS operations were still performing at a reasonable speed (ie, the whole Netapp was not locked up). Any ideas on a bug or limitation on either the Linux or the Netapp side with regards to large (70,000+ files) directories? Info: Netapp F760C ONTAP 6.1.2R3 Linux 2.4.20 (Redhat) Mount options: rw,hard,intr,vers=3,proto=tcp,rsize=32768,wsize=32768 Cheers, Chris -- Chris Miles http://chrismiles.info/

Maintenance on a filer with FCP connections...
by Don Hickey 01 Dec '03

01 Dec '03

When rebooting a filer that has SAN connections via FCP what is the "proper" procedure? Should all LUNs be unmounted from their respective systems first? Is a sync all that's required or is that even necessary? We have a few oracle databases on netapp LUNs and I need to upgrade the os and reboot. Just didn't want to shoot myself in the foot. thanks, -- Don

a dying man's plea
by larry moore 29 Nov '03

29 Nov '03

Greetings to you and your family in the name of God. In my search for a reliable and God fearing person and having gotten your contact through prayers and painstaking efforts I have decided to seek your help in carrying out my last wish .My names are Larry Moore. I'm a 65 years old man and a British living in Dubai (United Arab Emirate). I was a merchant and owned two businesses in Dubai. I was also married with two children. My wife and two children died in a car accident six years ago. Before this happened my business and concern for making money was all I lived for. I never really cared about other values in life. But since the loss of my family, I have found a new desire to assist helpless families. I have been helping orphans in orphanage/ motherless homes. I have also donated some money for humanitarian needs in Sudan, South Africa, Cameroon, Brazil, Spain, Austria, Germany and some Asian countries. Only recently I saw on television the colossal loss of pro perties and livelihood of people in Canberra, Australia through fire. I was moved with great pity and compassion that I decided to make a contribution on assisting people over there. Before I became ill, I kept $12.5 Million in a long-term deposit account in a finance company . Presently, I'm in a hospital where I have been undergoing treatment for oesophageal cancer. I have since lost my ability to talk and my doctors have told me that I have only a few months to live. It is my last wish to see this money distributed to victims of this fire outbreak in Australia and other charity organizations. Because relatives and friends have plundered so much of my wealth since my illness, I cannot live with the agony of entrusting this huge responsibility to any of them. Please, I beg you in the name of God to help me collect the deposit and the interest accrued from the company in Canada and distribute it accordingly. Use your judgement to distribute the money and keep 5% of it t o yourself. Feel free to reimburse yourself when you have the money for any cost you incur during the process of collecting and distributing the money. If you are willing to help, please reply as soon as you can. May the good Lord bless you and your family. Regards, Larry Moore ---------------- Powered by telstra.com

Root recovery without diskettes? Ulp.
by Professor Frink 28 Nov '03

28 Nov '03

I have a F740 with 4 FC9 7x36G shelves that I'm prepping for putting up for sale, and want to scrub the old corporate data off of it. Unfortunately, the root password is long since been lost, and the OnTap diskettes are not available (in the ex-wife's house in a bitter divorce, d'oh!). Is there any way to recover the root password somehow without the original floppies; I'm even willing to pooch all the data, since I want it scrubbed anyway. Any thoughts would be greatly appreciated. As it is, the unit is just one deafening white noise generating, air blowing, heating system. :( Thanks. _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…
