F740 at home -- please help me!
by mikka makka 07 Nov '04

07 Nov '04

Hi all, Last year I inherited an F740 filer with two FC9 shelves (7x36 GB disks). I used it happily at home for a few months and then a disk began to fail -- one had already failed, so that put the unit out of commission although luckily I was able to get all my data off it before total lossage. I bought a couple of Seagate ST136403FC drives -- the same model number as in the drive carriers -- off ebay and tried swapping them in, but no luck; the system wouldn't recognize them. On a hunch that it might have to do with firmware I tried swapping the drive's controller boards (old drives' controllers with new drives), but that didn't work either; the system wouldn't come up, dumping core for some reason. I figured the drives themselves probably needed to be zeroed/initialized/labeled in some way that made them acceptable to the Netapp, but I couldn't figure out any way to get the Netapp up and into a mode that would let me do that. Finally, lacking documentation for the system, I gave up. Fast-forward a little, I just inherited a second filer, an F720, also with two FC9 (7x36) shelves. As far as I know all disks good. Unfortunately it won't boot up (it finds and loads the image, gives the "Initializing PCI devices" and then suddenly reboots itself, without even dumping core). I'm not sure what the problem could be. I tried plugging in some of the disks from the new shelves in place of the bad disks in the old one, and now the 740 starts up and gives me a "File system may be scrambled" message -- well, of course it is, since the replaced disks contain who-knows-what, but I don't see how I can proceed from there. I'm not worried about getting back the original file system as I backed it up -- I just want to clear everything out and make a new one. The situation seems to me to be this: I've got an F740 (and a spare F720), and four shelves with a grand total of 26 good, identical, disks (and maybe even 28, if I could get the drive controller swap to work). That's 900GB of storage. I'm sure I should be able somehow to hook the four shelves up to the 740, reinitialize the whole system and all the drives somehow, and start afresh with a working 900GB filesystem. But I don't have the docs and floppy or whatever that came with the filers and I have no idea how to proceed given that the filer won't even start up to give me a command prompt that I might be able to work with. I'm not sure if I would need to boot from a floppy (I don't have one) or what... Is there anyone out there who could help, in any way? I'd be forever grateful... For the few months I had the 740 running, it was heaven -- amazing having a file server like this at home, even though I was using only the smallest fraction of its capabilities. Now that I have four disk shelves, I'm really motivated to get it working again, but I'm truly stuck without documentation Thanks so much for any help you could offer, Adam Jacobs mikkamakka(a)hotmail.com . _________________________________________________________________ Express yourself instantly with MSN Messenger!

re: Routing question
by ferdberfl＠netzero.net 05 Nov '04

filers don't have any capability to route data between interfaces. There's nothing you need to do to make sure they filer isn't doing any routing. AFIK it is a common use of filers in mixed high security/non secure environments to share common data through filer interfaces connected to both networks. Note, you will need routing entries to provide paths to networks behind the 2nd interface to the private network. The filer can only point to one gateway for (a 0.0.0.0 entry in the routing table). All other paths off of connected networks have to be pathed via static route table entries. -----Original Message----- From: Matt Phelps [mailto:mphelps@cfa.harvard.edu] Sent: Thursday, November 04, 2004 6:30 AM To: toasters(a)mathworks.com Subject: Routing question Hi all, I want to add a second nework interface (actually a vif, but it shouldn't make any difference) and attach it to a private network on a beowulf cluster; but I want to also keep the current interface to our public network up.

CIFS / NFS Authentication problem
by Geoff Hardin 04 Nov '04

04 Nov '04

Ok toasters, I've got a brain buster for you... Here's the situation: I have a filer running ONTAP 6.1R1P1 (and no, I can't upgrade) with a qtree (/vol/vol0/cifs) set to UNIX style security. The qtree is owned by a user and a group. There is a directory, /vol/vol0/cifs/test, in this qtree owned by this same user and group, and the UNIX permissions are 2775 (drwxrwsr-x). From a UNIX system, I can create new files, delete files, edit files, and rename files, and the file permissions are correct (owned by me and the group that owns the directory). Here's where it gets tricky. The qtree is shared via CIFS as \\TOASTER\cifs. The share is set up with everyone / Full Control (because we control access via UNIX groups and users). I can see the directory, I can modify existing files, but I can not delete files, create new files, or rename files. The Windows clients are Windows 2000 and Windows NT 4.0. My UNIX account and my Windows account are set up correctly in the usermap.cfg file. The local /etc/nis_group file is updated and correct. I am able to write to other shares on this filer, even to other directories in the share that have different UNIX permissions (i.e. 0755, 0775, or 0777). What am I missing? Is this a bug, or just an ID-10t error? Thanks, Geoff P.S. - I just checked my credentials using the `cifs sessions -s <username>` command and it came back with only two of my UNIX groups, specifically, not the group that owns the directory in question. I have turned on the `options nis.group_update.enable', and run `options nis.group_update_schedule now'. The local /etc/nis_group file is updated with the correct information, but even after removing myself from one of the additional groups, running `wcc -x`, and `options nis.group_update_schedule now', my credentials still show up with the same two groups (even though I am no longer part of one of them). Hmmm

RE: Backup speeds across the network
by John Clear 04 Nov '04

04 Nov '04

Our FAS250 runs about the same speeds as the F760 it replaced. It can do 2-3 NDMP sessions at 20MB/s. Quantum's newer libraries doesn't have NDMP native drives any more, but use Dinostors instead. 4.5MB/s is pretty bad performance. Unless the Sun is really overworked, it should be able to do better then that. I have a Ultra60 with four local drives (non-NDMP) and it can do >10MB/s per drive. John -----Original Message----- From: Geoff Hardin [mailto:ghardin@dalsemi.com] Sent: Tuesday, November 02, 2004 4:15 PM To: John Clear Cc: 'Geoff Hardin'; toasters Subject: RE: Backup speeds across the network Currently we are seeing about 4.5 MB/s from the filer (F760) to an LTO-2 drive attached to a Sun V240. Unfortunately, we do not have any data on the FAS270 yet, so we can't really test it, which is why I was looking for other's results. We looked at the DinoStor tape hosts and have been interested in using them for years, but we couldn't justify the additional price when there are libraries that have the functionality built-in already. From our own evaluations though, we highly recommend using the DinoStor devices if your library can not be attached to the network.

Vscan
by SKIP HOFMANN 03 Nov '04

03 Nov '04

Hi all Quick question how do I add an extension to vscan to not be scanned? If im understanding this correctly the filer has a list be default of extensions that it will scan, and if I remove a extension from the list then the file won't be scanned? Is this correct or do I also have to manually tell the filer not to scan an extension. Also we are using Trends filer protect for our FAS 250, can anyone tell me if intelliscan works on the filer the same way it would work on a windows server. As I understand intelliscan feature if the file is not on the Trend database of known viruses then the file doesn't get scanned .

OFF: NEBS compliant NAS
by Edward Hibbert (eh＠dataconnection.com) 03 Nov '04

03 Nov '04

This probably isn't directly NetApp related - though I'd love it if it were. Does anyone know of a rack-mountable NAS which is NEBS compliant and no more than 19" wide and 20" deep? Regards, Edward.
