Disk Hardware Questions
by Steve Evans 29 Jul '03

29 Jul '03

Some questions. . . 1. I have a DS14 shelf with 36gb disks, and FC8 shelf's with 18gb disks. Each shelf has a HotSpare. If a 18gb disk fails will it for sure use the 18gb hotspare or is there a chance it will pickup the 36gb hotspare? 2. I'm thinking about migrating all the data on the 36gb drives (including /etc folder) to fewer 72gb drives. What's the best way to do that? Can I add the new 72gb disks to the volume with 36gb drives, then start to remove 36gb drives over time? 3. Right now I have the FC connection going like this: Filer Head --> FC8 shelf --> FC8 shelf --> DS14 shelf. All of the important data is on the DS14 shelf. The FC8 shelfs aren't on support contracts, and don't have any important data at all. (mostly system images, software install files, etc). Is this a bad idea. How much risk am I putting my important data on the DS14 shelf. We're thinking about getting another FC HBA with two ports because right now we just have a single FC cable. Then I would plan on putting DS14 shelf on the Dual Port HBA (with redundant paths) and putting the FC8 shelfs on our current HBA by itself. 4. With the sysstats tool, what kind of numbers can I expect to max out on, on the Disk KB/s? Thanks, Steve Evans SDSU Foundation

Vol copy'ing a ZCS volume to a BCS one
by Chris Thompson 28 Jul '03

28 Jul '03

What happens when one does a "vol copy" from a volume that has zoned checksums active to one that is made out of BCS (520-byte sector) disks? Do the blocks that were reserved for zone checksums on the source volume become free when the target volume is put online? Or does the latter remain a zoned checksum volume even though it is made up of BCS discs? The documentation doesn't seem to be very clear on this point, and I can't do the experiment (yet) ...

Edward, The drives in your system are X225B. They are ZCS 36GB disks. You can use the X224A, X225A, X225B or X225C which are all ZCS 36GB disks for the StorageShelf FC9.

URGENT ASSISTANCE
by JOSEPH WILLIAMS 26 Jul '03

26 Jul '03

JOSEPH WILLIAMS DIRECTOR PROJECT IMPLEMENTATION (MEMR) Dear Sir, I am an Engineer with the South African Ministry of Energy and Mineral Resources and I am also a member of the Republic of South Africa Contract Award and Monitoring Commitee in the Ministry of Energy and Mineral Resources. It is a pleasure involving you in this project. Although, this may sound strange but I seek your indulgence and pray you view it seriously. Two years ago, a contract was awarded to a foreign firm in the Ministry of Energy and Mineral Resources by my committee. This contract was over invoiced to the tune of US$14.3Million. This was done delibrately. The over invoicing was a deal by my commitee to benefit from the project. We now desire to transfer this money which is in a suspense account with the MEMR into any oversea account which we expect you to provide for us. For providing the account where we shall remit the money, you will be entitled to 30% of the money, 10% will be set aside for expenses incurred by both parties during course of transfer, while the remaining 60%will be for my partners and myself. I would require the following: 1)Bank details ( Name and address / Account no/Beneficiary name ) 2)Private Telephone and Fax number of Beneficiary The above information would be used to make formal application as a matter of procedure for the release of the money and onward transfer to your account. It does not matter whether or not your company does contract projects of this of this nature described here, the assumption is that your company won the major contract and subcontracted it out to other companies. More often than not, big trading companies or firms of unrelated fields win major contracts and subcontract to more specialized firms for execution of such contracts. We have strong and reliable connections, top government contacts at the South Africa Reserve Bank and Ministry of Finance and we have no doubt that all this money will be released and transferred if we get the necessary foreign partner to assist us in this deal. Therefore, when the business is successfully concluded we shall through our connection withdraw all documents used from all the concerned Government Ministries for 100% security. We are civil servants and we will not want to miss this opportunity. Please contact me immediately through my above Telephone or email contact, whether or not you are interested in this deal. If you are not, it will enable me scout for another foreign partner to carry out this deal. But where you are interested, send the required informations aforementioned herein without delay as time is of essence in this business. I want to assure you once again that this transaction is 100% risk free both now and in the future. I await in anticipation of your fullest co-operation. Yours faithfully, JOSEPH WILLIAMS

connection refused error when trying to access filerview
by DFinn＠studentadvantage.com 25 Jul '03

25 Jul '03

I know this used to work a while back but it no longer does. I don't use it but another admin here would like to be able to use it to make changes. It works fine on the three other netapps we have here. This one is running an older version of OS though, it's at NetApp Release 5.3.5R2. Under options httpd.admin.enable is set to on. I can get in and bring up the java window, i don't get the error message until I try to access something that requres the root password. When I provide it I get the following error: Error communicating with host 10.209.68.211 msg=Connection refused nothing shows up in the message log for errors. Is there a way to turn on logging for this to try and get more info about what's happening? I've also tried disabling it and enabling it and that doesn't seem to fix the problem. I know the password is correct because I can telnet into the console just fine. Could it be looking for a different password other than the root password? I also ran the password command and changed the root users password and then tried to access filerview with the new password and that didn't work either. Any help would be really appreciated Thanks Dan
