RE: nightly.1 busy: snapshot rollovers not happening
by Benn, Paul 13 Apr '99

13 Apr '99

Yes, there's a sample script (batch file) that can be scheduled with the AT service. Here's a snippet from section 5.2 of the doc: Once the filer and Windows NT have been setup, schedule a batch process using the Windows NT "at" command. The following batch file, which uses NT Backup, is included as a reference: REM In this example, 'filer5' will be used as the name of the filer REM The qtree is called 'qtmixed,' which resides on a single REM volume filer. The default volume name is vol0. REM REM Delete the snapshot created by the previous run of this process rsh filer5 -l root snap delete vol0 openfiles REM REM Turn off oplocks, telling clients to release the file rsh filer5 -l root qtree oplocks qtmixed disable REM REM Create a snapshot directory called openfiles rsh filer5 -l root snap create vol0 openfiles REM REM Re-enable oplocks rsh filer5 -l root qtree oplocks qtmixed enable REM REM Map a drive letter to the filer's root share net use f: \\filer5\c$ REM REM Run the backup command - in this example NTBackup. REM Notice that '~snapshot' is used instead of '.snapshot' start /normal /b ntbackup backup f:\dir\~snapshot\ /hc:on /t normal REM End of file The above batch file (less the last few lines, launching a backup command) could also be used as a pre-job process with almost any Windows NT backup package. -----Original Message----- From: Mark Muhlestein [mailto:mmm@netapp.com] Sent: Monday, March 01, 1999 10:56 AM To: toasters(a)mathworks.com Subject: Re: nightly.1 busy: snapshot rollovers not happening The best way to do this is to create a special snapshot specifically for the backup, then delete it when the backup completes. This avoids the problem of the snapshot being changed out from under you. And this can all be automated with scripts. See Paul Benn's message for a pointer to a description of how to do this.

Cifs permissions ???
by Jason Middlebrooks 13 Apr '99

13 Apr '99

The following is happening. Any ideas of what to do? 1. I have created a folder called test. 2. Within server manager I create a share for test. 3. Withing user manager I create a user called dude, a global group called dudes_global with several users, and a local group called dudes_local with several users. First I give one person (dude) permission to access test and everything works fine. (Dude can access test and nobody else can) Second I remove dude from the permissions list, add a global group (dudes_global) to have permission to access test and everything works fine. (Only the people in dudes_global can access test nobody else can) Third I remove dudes_global from the permissions list, add a local group (dudes_local) to have permission to access test and then it happens. (Nobody can access test and I mean nobody. I keep on getting not accessible / access is denied) Anything wrong with using local groups?? Is there any setting that needs to be changed in NT or on the Filer??? F720 DataOnTap 5.3 and all the other stuff...

NDMP support, Arkeia and others
by Dane Jasper 13 Apr '99

13 Apr '99

I'm interested in seeing NetApp work closely with backup software vendors such as Arkeia to further NDMP support. Arkeia now supports backup of the Cobalt product line, including their (non exandable, small scale) RAID-1 NAS product. It would be great if NetApp would contact Arkeia and extend any assistance they can in the extension of the Arkeia backup tool. This type of support can only be beneficial for both companies, and end users too! Arkeia is at http://www.knox-software.com/. Arkeia is similar to Legato's Networker product, but supports other server platforms and costs less. BRU is another backup product where I'd love to see NDMP support included. BRU is at http://www.estinc.com/. NetApp customers, please voice your support to NetApp if you see value in more support for NDMP. -- Dane Jasper Sonic (707)522-1001 (33.6kbps) (707)522-1000 (Voice) mailto:support@sonic.net http://www.sonic.net Key fingerprint = A5 D6 6E 16 D8 81 BA E9 CB BD A9 77 B3 AF 45 53

Dump command issues?
by Mike Ball 13 Apr '99

13 Apr '99

Currently we have a F720 filer and a ATL Powerstor L500 tape library attached locally. We are running into a issue when we try to dump to multiple tapes. If we use the command below, it is supposed to dump our entire vol0 (90GB of data) to multiple tapes in our tape library. rsh -l dump 0uf urst0a,urst0a /vol/vol0 Unfortunately, the dump command above backs up to the first tape, then rewinds the tape when it is full but never unloads it. The first tape is then overwritten as the dump continues. The dump command above does not unload the tape and continue the dump onto the second tape in the library. Has anyone else experienced this before, or does anyone have any recommendations to correct the problem? Thank you, Mike Ball

RE: Swapping disks between shelves (F740 cluster upgrade)
by Dawn Hamel 13 Apr '99

13 Apr '99

When you place the drives from the "old" filer into the drive bays of the "new filer", I would suggest that you boot from floppy and make sure that the new filer can see all the drives. Since you are using a new "head" ... then you are also going to be using a new NVRAM card. The NVRAM actually puts an entry into the labels of the disks so that the disks know that this data belongs to this filer/NVRAM card. This is just in case there is any leftover data in the NVRAM card before shutdown ... When you boot, the filer will want to re-write the labels on the new drives placing the new NVRAM card signature onto the raid labels ... If you boot and all the drives are not seen, some of the labels will be re-written and some will not. You will then have mismatch raid labels and the machine will not boot (too many disks missing from the raid array) ... You will then need to go in and edit the raid labels (not fun) So ... the short of all this is to boot from floppy and make sure that the new filer sees ALL the disks -----Original Message----- From: Jay Soffian [mailto:jay@cimedia.com] Sent: Friday, April 09, 1999 8:33 PM To: toasters(a)mathworks.com Subject: Swapping disks between shelves (F740 cluster upgrade) We have an F740 with three FC-AL shelves and 15 9GB disks.

RE: Not a server
by Benn, Paul 12 Apr '99

12 Apr '99

This may sound too simple but it seems as if there is no physical connection between the filer and the NT box. It doesn't really sound like a filer specific issue. Is it safe to assume that you're using the NetWare Migration Tool that ships with NT server and that the NT server has TCP/IP installed and configured? Is the filer licensed for CIFS and does it have a machine account in the domain? Can you see the filer from the NT server when NOT outside of the NWM Tool? Sorry for the list of questions. Just checking the basics.

Now I have the following question: I want to migrate from Novell Netware 3.x to my Netapp (F720). I want to realise this with a programm called "Netware Migration tool (Nwconv). If I want to choose a Windows NT server and I select the Netapp (he is in a domain called D00) the programm comes back with the following problem: "cannot connect to server: The Network name cannot be found". I don't know if this is a problem on the Netapp (perhaps a services or something) or that I have to look somewhere else Greetings, Jan-Dirk

Re: Upgrade F330 to Data ONTAP 5.2.1

Stale NFS file errors are different from the NFS over TCP problem. I could be wrong, but I don't remember stale filehandles being an issue except for certain broken *down*grades. Check the upgrade notes. In addition to switching all clients to UDP, you can put this line into your rc file right before you reboot. options nfs.tcp.enable on You can still switch clients to UDP, but you won't have to wait until every last one has switched this way. - Dan

Need help regarding quotas
by Patrick.Day.B＠bayer.com 09 Apr '99

09 Apr '99

We are currently migrating the home directories of 1200 users to our 740 (dot 5.2.1) All of our clients are either NT 4.0 (85%) or Win 95 (15%) and the filesystem on the netfiler is NT only. The quota file is configured as such: * user@/vol/uservol/users 100M #default Users Which should give everyone a 100Mb limit by default. Immediately after moving a user (with BackupExec-thus preserving the acl's) i run a program from TrustedSystems called reacle.exe that will allow me to force ownership of the files to the proper owner. All this said and done, the quotas are working correctly (no error messages) and are showing the users and thier limits. However, the actual file space accredited to the users is incorrect. It seems that only the files that they, themselves touch are assigned to them. I have users who i know are owners of more than 100Mb of files who, when the quota report is running, only appear to have 40K credited to them. Here is an example report for users who have more than 80Mb in their home directories. Type ID Volume Tree Used Limit Used Limit Quota Specifier ----- -------- -------- -------- ------- ------- -------- -------- ----------------- user * uservol users 0 102400 0 * user exral uservol users 2260 102400 29 user exjjr uservol users 90876 102400 188 user extyd uservol users 20 102400 3 user exjaw uservol users 1212 102400 4 user exaau uservol users 1692 102400 36 user exusl uservol users 960 102400 10 user extxf uservol users 168 102400 8 user exjec uservol users 4332 102400 15 user mitji uservol users 1336 102400 2 Is there anything i need to do that doesn't require user interaction? Any input would be appreciated. --Patrick Day System Admin. Bayer Corporation.
