RE: DLT8000
by Kim, Christopher 15 Dec '00

Using Data ONTAP 5.1's "cloned_tapes" for Unsupported Tape Drives You can attach an "unsupported" tape drive to a filer and use it successfully with the cloned_tapes feature, new in Data ONTAP 5.1. To use an "unsupported" tape backup device, the ASCII file /etc/cloned_tapes in the root volume must contain a list of unsupported tape backup devices connected to the filer. To enable this option, do the following: 1.Halt the filer and install the tape adapter (if necessary). 2.Attach the tape drive to the filer and power up the drive. 3.Power up the filer. At boot, there will be an error message telling you the tape drive is unsupported. 4.At the filer console, type mt -f rst0a status. This command will create the file /etc/cloned_tapes. 5.Edit the /etc/cloned_tapes file to map the product ID of the unsupported drive to one that is supported. For example, you can add to this file the following line: QUANTUM DLT8000 EMULATES QUANTUM DLT7000 6.At the filer console, type mt -f rst0a status again. 7.Type sysconfig -t to verify that the drive appears, along with all your previously installed devices. 8.Reboot the filer. Note: At boot, you will still receive an error message about an unsupported tape drive, but the officially "unsupported" tape drive will work successfully. For more information, see the "New features in Data ONTAP 5.1" section of the Data ONTAP 5.1 Release Notes.

Filers, IIS5 and Pass-Through Authentication
by Benn, Paul 15 Dec '00

15 Dec '00

Hello Toaster People, I had been working with a few of you on how to configure IIS5 with filers for pass-through authentication. The necessary steps along with a number of other updates have been incorporated into an updated white paper on IIS. The URL hasn't changed but here it is for convenience: http://www.netapp.com/tech_library/3078.html Thanks to those of you who sent me your comments on the original paper. I ended up making all of the suggested changes. Best Regards, Paul Benn Network Appliance

RE: Setting up a VIF
by Fox, Adam 15 Dec '00

15 Dec '00

Once you set up a VIF, the individual interfaces in that VIF lose their individual configuration data. So the VIF takes a single IP address, netmask, broadcast, and MAC address. Once the VIF is created, if you run ifconfig -a you will see that all of the member interfaces of that VIF automatically show up with the same config. info. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com -----Original Message----- From: Maglinger, Paul [mailto:PMAGLINGER@scvl.com] Sent: Thursday, December 14, 2000 7:42 PM To: 'NetApps list server' Subject: Setting up a VIF We're looking at taking our Gigabit II Ethernet card and the 10/100 interface that comes with our 740 and creating a VIF.

RE: Veritas & Filers, or: to NDMP or not to NDMP ...
by Braunschweiger, Udo 13 Dec '00

13 Dec '00

there are some points worth to think about before you decide how to do backups. Using ndmp instead of nfs has the follwing impacts: ndmp is blocklevel based, nfs of course is filebased If we backing up a volume that is holding a database, usually the "minimal read ahead" option is set to meet the needs for accessing the database-files. This impacts nfs backup performance dramatically. On the other hand, in order to use ndmp, we need expensive client software for our backup software. But even if we use ndmp to send the data over the network (not a local tapedrive) this backup method is not affecting cached data in the readcache of the filer. This can be a very important reason for ndmp, especially if we are running a database with 7 times 24 hours uptime. On On-Tap Releases 5.3.5 or newer, the ndmpd version-behaviour can be set using the "ndmpd version [2,3]" command on the filers console. -----Original Message----- From: Francett, Robert D (SAIC) [mailto:FranceRD@bp.com] Sent: Dienstag, 12.

Therefore no worries impacting net with backups. Never used BudTool. Upgrades to DOT have never been a problem. NOW keeps a page which lists NB versions sanctioned with the various DOT releases.

I am switching from BudTool to Veritas Netbackup. It seems, if I understand things correctly, that I can either back up my filers over NFS, or I can use NDMP and back them up to a locally attached tape drive, or to another filer with a locally attached tape drive. NDMP seems the way to go, for performance and speed reasons. However, I stopped using NDMP with BudTool, because everytime I had to upgrade either BudTool or OnTap, I ran into compatability problems between the differing NDMP implimentations. What has been the experience of those of you who are using Veritas and have tried the above solutions? Which method do you suggest I use, and why? -ste -- Office: (908) 582-7629 Cell: (908) 672-6456 Pager: (888) 290-2057

Samba sharing an NFS mounted drive (netapp)
by Stoo Davies 13 Dec '00

13 Dec '00

I posted this on the Samba mailing list earlier, but if anyone here has tried Samba sharing an NFS mounted drive info would be appreciated. Thanks Stoo Hi, I hope someone will be able to help me with a strange problem that started after an upgrade. A Redhat 6.1 based file server running Samba 2.0.5a has been sharing /home for a number of months. The /home mount was from a SCSI attached RAID array. We ran out of space recently so copied the files across to a netapp filer, and mounted /home from there. I know the filer can do CIFS, but due to existing file references and other services we need to maintain the Samba shares. Since the move we've started having some file locking problems, the M$ Access "Too many active users" message makes this look like the glibc 64bit file locking problem. My question is wether anyone knows of problems sharing NFS mounted drives with Samba? Thanks Stoo
