Adding drives to specific raid groups
by Page, Jeremy 25 Aug '08

25 Aug '08

I know this is possible but I cannot for the life of me find the document detailing how to add a drive to a raid group explicitly. I have 2 aggrs with 3 raid groups each and 8 spare drives. I'd like to add one drive to each raid group but cannot find the syntax, can anyone link the correct NOW URL?

Ndmpcopy v vol copy
by David McWilliams 20 Aug '08

20 Aug '08

We are adding a shelf of faster disks onto our existing FAS270C. We want to copy our Oracle database volume from the existing disk to the new shelf. We have considered usig either ndmpcopy or vol copy. Is there a performance Enhancement of one over the other, or is there a better method?

by Jody Martin 20 Aug '08

20 Aug '08

Hi all, Is it possible to have quota soft limit warning mailed to the respective user or administrator from a filer when they are reached? If not, is there any tool available for doing this? The user only gets an error when he/she exceeds the hard limit. Any assistance would be greatly appreciated. Regards, Jody

NDMP speed measured in the field
by Van Eyken Michiel 20 Aug '08

20 Aug '08

All, Just curious if the people here in this distribution list who are using NDMP backups can give me their NetApp config (filer type & number of disks) and their actual backup throughput. If it's possible also the number and drive types connected and used backup software. Thanks in advance With kindest regards, [cid:image001.gif@01C902A4.ADD10AA0]<http://www.uptime.be> email-disclaimer<http://www.uptime.be/disclaimer.html> "Computers are like air conditioners - They stop working properly when you open Windows"

how to "move" an existing snapmirror to new network interfaces?
by Todd C. Merrill 18 Aug '08

18 Aug '08

I have lots of existing q-tree snapmirrrors of the form: srcfiler:/vol/volM/qtreeX destfiler:/vol/volN/qtreeY "srcfiler" (DNS name) is the e11 interface on srcfiler "destfiler" (DNS name) is the e9a interface on destfiler We just built a "dedicated snapmirror/backup" network and added the following: "srcfiler-backup" (DNS name) is the e0 inteface on srcfiler "destfiler-backup" (DNS name) is the e11a interface on destfiler Subsequent 'snapmirror update -S ...' commands (we don't use snapmirror.conf) still use the non "-backup" network links. I'm not seeing the counters on the "-backup" links increment via the `ifstat` command. The $64,000 question: --------------------- How do I "move" these snapmirrors to the "-backup" network links...without, of course, re-initializing them? I'm expecting, in the end, to see `snapmirror status` give back to me: srcfiler-backup:/vol/volM/qtreeX destfiler-backup:/vol/volN/qtreeY and see the counters on e0 on srcfiler and e11a on destfiler increment.

Re: (resolved summary) 7.0.6 to 7.2.5.1 upgrade
by Jerry 16 Aug '08

16 Aug '08

I talked with a professional services guy who does this regularly. He said always do the disk fw first the night before or some amount of time before. This was evident by his knowledge up front that it takes 2.5 seconds per drive. In fact, the full upgrade guide mentions it specifically: 7.2 upgrade guide, page 84 3. Verify whether you need to update disk or disk shelf firmware. Note: You should ensure that any required disk firmware and disk shelf firmware updates have completed before beginning a nondisruptive upgrade. In particular, you should upgrade disk firmware at least one day before beginning a nondisruptive Data ONTAP upgrade, because automatic background disk firmware updates can take a long time in large-capacity systems. --- On Sat, 8/16/08, Eric Grancher <eric(a)grancher.fr> wrote: > From: Eric Grancher <eric(a)grancher.fr> > Subject: Re: (resolved summary) 7.0.6 to 7.2.5.1 upgrade > To: juanino(a)yahoo.com > Cc: "list toasters" <toasters(a)mathworks.com>, "Strickland, Michael" <Michael.Strickland(a)netapp.com>, "Lawler, Steve" <Steve.Lawler(a)netapp.com> > Date: Saturday, August 16, 2008, 3:02 AM > thank you for sharing the solution. > Did you get this as a general statement from NetApp, > "you should > always do the disk fw upgrades before a non-disruptive > upgrade", > or is this specific version/case special? > > regards, > eric > > 2008/8/16 Jerry <juanino(a)yahoo.com>: > > Thanks Steve (and others who responded).

7.0.6 to 7.2.5.1 upgrade
by Jerry 16 Aug '08

16 Aug '08

Has anyone experienced an issue going from 7.0.6 to 7.2.5.1. I did an upgrade on my 940 cluster and when I attempted takeover the takeover never succeeded. The first head decided to reboot (without me running halt) but the second head never completed the takeover. After that it complained about version mismatch.

CIFS UNC share authentication delay
by J. Greg Mackinnon 15 Aug '08

15 Aug '08

We are experiencing a vexing delay when users on non-domain-joined Windows workstations attempt to connect to shares on our filers using a UNC share path. For example, if a user goes to start->run on Windows XP and enters the path "\\fileserver\sharename", they will see a delay ranging from two to ten minutes before they get an authentication prompt. Once authenticated to the server, there are no performance problems. If connecting using named credentials (either using the GUI "map network drive", or a command line "net use" command), this delay does not occur. We did an awful lot of troubleshooting. Eventually we turned on cifs login tracing (options cifs.trace_login on) and found the following revealing entry in our logs: toast: auth.trace.authenticateUser.loginTraceMsg:info]: AUTH: Delaying the response by 5 seconds due to continuous failed login attempts by user administrator of domain <WORKSTATION> from client machine <IP Address>. It appears that the Windows client is generating more login attempts than the filer thinks should be allowed! However, I have no ability to change the behavior of unmanaged Windows workstations, so I need to tune this from the server side. Does anyone know how to change the number of consecutive login failures allowed by the filer? What about changing duration of the delay? I have a case open with NetApp on this one, but they have not been able to provide answers so far. -Greg Mackinnon University of Vermont
