I dont think Multiplexing is on. I will check. Its a 7 slot robot with 1 drive.

Do you have mutliplexing turned on or off? Off is probly best. And when you say "slot" I assume you actually me drive? Or do you have a robot with only 1 drive and 7 tapes? Maybe you could mention which type of robot it is? Almost sounds like a L280. benr. -----Original Message----- From: Clawson, Simon [mailto:simon_clawson@mentorg.com] Sent: Thu 4/25/2002 1:38 AM To: 'toasters(a)mathworks.com' Cc: Subject: Backups to 6 tapes failing Hi!

Request for Input on Independant Filer tools
by Ben Rockwood 25 Apr '02

25 Apr '02

Hello Mighty Toasters, As some may have noticed recently, I've become very interested in monitoring tool development for the filers. I've recently had a minor breakthrough using SNMP tables and mutli-dimensional arrays in PERL. This is particularly interesting because it gives me the ability to develope tools that can run sorts on the raid tables, disk usage tables, and more. Here's the problem, most of the tools I'm building now have little to no value. They are amusing and fun to write, but especially if you use FilerView these tools are useless. While this is a credit to NetApp, I'm curious if there are any tools people would like to see. What types of monitoring tools would you guys like to see? Performance tools are pretty well taken care of with MRTG and Cricket, though it would be fairly simple to use an snmp polling loop to drop files into either a MySQL/PostGreSQL backend or maybe just a BerkleyDB and then run GNUplot on 'em for a more simplified Cricket replacement, but since Cricket is so trusted it's unlikely for any of my tools be replace it. In essence, I've solved the problems I need to solve and now what to find some way to use all the kool tricks I've learned in the proccess. Ideas? If nothing else, I'm hoping to write an article soon about how to easily develop your own in-house tools for the Filers, which is probly the most useful thing I could do. Thanx in advance.

RE: Tape drive recommendations
by Ben Rockwood 25 Apr '02

I can't resist to step in here. The battle of the tape format is continuing day by day. Many vendors are pushing people away from current DLT technology saying it's doomed, and that AIT isn't far behind. The big pushes are on LTO's and newer drives. I've had my eye on StorageTek for awhile now because they are doing some really neat things, namely FC to the drive in their T9840B drive. The T9940's are nice two with 60G native and 120G 2:1 compressed. But then it all comes down to your stratagy. If you have a small enviroment and you only want to back up, say 1-2TB, then you might like some of the 20slot AIT2/3 arrays from ADIC. SDLT is looking good with native capacities for 110G and higher with compression plus descent speed, however a key factor between DLT and AIT right now is also physical size. If you have a cramped facility you may not have adiquate room for DLT robots, which is where the nice and tiny AITs are handy. There are alot of choices. Currently I'm still liking LTO because it has 15MB/sec sustained rates per drive plus a 100G native capacity, but right now it probly comes down to cost more than anything. In which case, if you buy a robot, buy bigger than you need to so you can scale later. As for which is best specifically for a Filer, I know that you supposedly can put a robot directly onto a head, but I haven't seen anyone do it, and probly would opt to use a seperate gig-network with a dedicated backup server and anything I wanted on the back end of it. Maybe that helps. I hope.

Quantum/ATL P14000, gigabit Ethernet sdlt -- anyone else using this?
by Quentin Fennessy 25 Apr '02

25 Apr '02

We recently purchased a Quantum/ATL P14000 (2xP7000), configured with Gigabit Ethernet sdlt tape drives on a Cisco switch. We are using Workstation Solutions QuickRestore, version 2.7.10. We're trying to backup Netapps (F760s, 840s, 880s) via a Solaris QR host. Unsuccessfully. Is anyone else using the P7000 or P14000 changer? With Gig SDLT? With QR? Our challenges are legion. Are we alone? I'd like to correspond with or talk with someone who has made this configuration work. Thanks -- Quentin Fennessy Quentin.Fennessy(a)amd.com Office: 512.602.3873 Cell: 512.694.7489

Tape drive recommendations
by dwald＠kersey.yi.org 25 Apr '02

25 Apr '02

Hi all. We've been using DLT7000 drives off the back of our 740's for some time now, and are looking to upgrade. According to the NOW site, NetApps supports the SuperDL220, AIT-3 and some of the LTO's, among others. Capacity and throughput are somewhat close across the three types, I'm curious for any thoughts on which is preferred? Any horror stories on any of these with Filers? Thanks

REQUEST FOR HUMBLE ASSISTANCE.
by MR GORIS ACHA 25 Apr '02

25 Apr '02

Sir, REQUEST FOR HUMBLE ASSISTANCE. This letter is meant to contact you following knowledge of your esteemed self to help us out of this difficult situation that my family has been engulfed in since the death of my father and the breadwinner of our family. So please, consider this as a request from a family in dare need of assistance. I am Mr. Goris Acha from Angola, the first and the only son of late Brigadier Luis Acha communicating to you from Johannesburg, Republic of South Africa. I, on behalf of my family decided to solicit for your Assistance to transfer the sum of US$25.5milloin (twenty five million five hundred thousand united state dollars)inherited from my late father into your company or private bank account. Before the death of my father, he was a brigadier in charge of arms and ammunition procurement for the Angolan army. In his will, he specifically drew my attention to the sum of US$25.5million that he deposited in the safe box of a private security company in Johannesburg, South Africa. In fact he said and I quote, "My beloved son, I wish to draw your attention to the sum of US$25.5 million. I deposited the box containing the fund in a security company in Johannesburg, South Africa as valuables. During the war, I was very dedicated and committed to wining the war against the rebels until when I found out that senior army officers and government functionaries were busy helping themselves with government funds and properties sending them to foreign countries. Due to this, when I and former special adviser to the president were assigned by the president (Jose EduardoSantos) to purchase arms in South Africa, we saw this as an opportunity to divert the money for our personal use and shared it, of which I got a total sum of US$25.5million. I did this in case of my absence due to death so that you Goris, your two sisters Grace and Anne and your mother wouldn't suffer. You should solicit for assistance of a reliable and sincere foreign partner to assist you to transfer this money out of South Africa for investment. I deposited the box in your name and you can claim it alone with the deposit code. Your mother is with all the documents; take good care of your mother and your two sisters. Do not disappoint me! Good bye". After the burial of my father, we decided to move to South Africa where this money was deposited and withdraw it and put to use and was disappointed to learn that it is against the human Right law SECTION22 OF THE REFUGEES ACT NO 130 OF 1998 that asylum seekers in the country do not have the right to operate a bank account or operate an enterprise in the country. After much consideration, we arrived at conclusion that it will be of interest for us to contact a foreign partner to assist us transfer this money out of South Africa. From these words of my late father, you will understand that the lives and future of my family depend on this fund as such I will be grateful if you can assist us. Now what I will like you to do for us, as a foreign partner is to help us clear this fund from the Security Company using your name as the beneficiary of the fund. For your efforts, we are prepared to offer you 20% of the total sum while 10% will be set aside for expenses Incurred during the course of this transaction and the remaining 70% for the family's investment abroad which you will assist us to materialize. Please note that this transaction is risk-free and the major thing I ask from you is to assure me the safety of the money when transferred to your account. Your utmost trust, sincerity and confidentiality is highly needed in this transaction. Be kind to provide me with your private communication facilities for smooth and confidential link. Further information and arrangement will commence as soon as trust, confidence and good relationship is established. I shall be most grateful if you maintain the confidentiality of this matter. Should this meet your utmost consideration, please give me your earliest reply through my email address. Best regards, Mr. Goris Acha

Any Tru64 Unix (nee Digital Unix, nee nee OSF 1) V5.1A users out there?
by Matt Phelps 24 Apr '02

24 Apr '02

Here's one... Anyone out there have read-only exports on a filer mounted by a Tru64 Unix alpha? We've upgraded a few of our Alphas to 5.1A (from 4.0x) and now the "pwd" and "df" commands fail on the read-only exported directories. They generate an error having to do with a read-only file system. The very same directories work fine with DU 4.0x. I've opened a call with Compaq, but I was wondering if anyone else on the list has run into this. -- Matt Phelps System Administrator, Computation Facility Harvard - Smithsonian Center for Astrophysics mphelps(a)cfa.harvard.edu, http://cfa-www.harvard.edu/~mphelps
