Re: Oracle using NetApp
by Joseph Bishop 20 Aug '02

20 Aug '02

Hello, We have 6 servers hitting our NetApp 760 with about 25 instances. Love love love the filer. I have not seen a problem with the database even if the network goes down for some time (20 minutes and more). The only hiccup I have seen is if the filer is rebooted while databases are operating. A control file that is located on the filer may have a lock held against it when it comes back up. We run 1 filer and 2 local control files. If that happens, delete the filer based control file and replace it with a copy from the local set. Then your database will restart. Cheers, Joe At 09:35 AM 8/20/02 -0400, Brian Long wrote: > > 1.

Hi, One of my customers are running snmp_traps on their F85 filer , he audits his other filers with TNG unicenter version 2.4. I have tried to find information about TNG unicenter with filers, but without any luck. Do any of you have experience with how to integrate filers "snmp_traps" with tng unicenter , configuration? I'll be glad to hear from you:) Best regards Vibeke Østensvik

Re: qtree Move Between Vols
by Vincent Bohossian 18 Aug '02

18 Aug '02

Hi Ed, There is a product called RainStorage, by Rainfinity, that lets you move files between NetApp filers without interrupting access to those files. That is while the files are being moved users can still read and write to them, and no connections are lost. It is a box that one plugs in the same switch the filers are connected to. The box will put itself in-band when a move is initiated, and will go out-of-band when the move is finished (or later if needed). During the move, as clients access the files, RainStorage keeps both source and destination up to date by duplicating write requests. Once the move has finished only destination files are accessed and the source can be deleted. The product has been running for a while already at NetApp SE labs, they seem quite excited about it. Let me know if you need more info about it (data sheet etc..). It is a recent product, so it is not yet on the web site.

RE: qtree Move Between Vols
by Mike Carroll 18 Aug '02

ndmpcopy was originally created for copying files between filers, but it works extremely well for operations on the same filer. NetApp has made ndmpcopy part of the base OS in their later releases. It's definately on 6.2.1 but I'm not sure when they snuck it in there.. If you don't like ndmpcopy for Solaris and if upgrading your filer isn't an option, I'm afraid your stuck with very network intensive copies. They copy the files from filer to client to filer again... blah!! Hopefully someone else knows of another option for you I had a lot of success utilizing ndmpcopy on our Solaris admin hosts... # ndmpcopy filername:/vol/volume/qtree1 filername:/vol/newvolume/qtree -----Original Message----- From: Ed Alexander [mailto:esalexa@msai.mea.com] Sent: Friday, August 16, 2002 10:01 AM To: toasters(a)mathworks.com Subject: qtree Move Between Vols I apologize in advance if this is in a FAQ or in the archives. I couldn't find an answer there, so... I've just brought a new vol on-line and need to move some qtrees off other vols that are filling up. All vols are attached to a single F820 and my admin host is running Solaris 8. What is the best (read: fastest) way to move a qtree between vols? The qtrees I'm moving are between 5 and 65 Gb in size. I've looked at ndmpcopy on the ndmp.org site. It's intended for moves between filers, but should work fine for moves within the same filer. Also, the site claims it's been tested on Solaris 2.5.1. Have others compiled and used it on Solaris 8? Are there other viable options besides ndmpcopy? I'd appreciate any advice from others who have gone down this road. TIA.

RE: Netapp BMC Patrol

I'm always happy to hear the truth, even when it hurts. I'm feeling no pain just now though, and I have to say that my experiences with Patrol incline me to agree with your summary. Nice to hear that it's not just me that thinks that way. -- -Mark ... an Englishman in Delft ...

Do you want us to tell you the truth? Seriously, BMC is a collection of programs that they 'acquired' and plugged in together. In my opinion, it's very poor quality for what you pay for. -----Original Message----- From: mds(a)gbnet.net [mailto:mds@gbnet.net] Sent: Friday, August 16, 2002 1:42 AM To: Nail, Larry; 'markallen'; toasters(a)mathworks.com Subject: RE: Netapp BMC Patrol Has anyone ever had a good experience implementing Patrol with anything? -- -Mark ... an Englishman in Delft ...

autologout with secureadmin
by daveb＠esat.net 16 Aug '02

16 Aug '02

Hi, I recently began testing secureadmin 2.1.1D2 (version that will work happily with openssh). I left myself logged into one of our filers last night and this morning I came in to see repeated messages on my filer session... autologout: session idle for too long But, my session had not been closed at all. Does autologout not work with secureadmin or is it just broken in this release?

Multiple Subnet's
by Steve Evans 16 Aug '02

16 Aug '02

Right now I have my Filer 810 connected via a gigabit Ethernet to our main internal subnet. I'm thinking of taking one of the 100 bit ports and sticking that in the DMZ. The DMZ nic won't have any access at all to anything on our internal subnet. I'm thinking about doing this so our web server could store it's files on their easily. Could somebody comment on this idea. Steve Evans Computing Services (619) 594-0653
