Neither OnTap or NetBackup support direct access restore in currently shipping releases. This is a complicated problem to solve in a dump-style backup. The only suggestion I can make to improve restore speed is to breakup the backup into smaller dumps. If you are doing full volume dumps now then this may be less efficient as far as backup speed is concerned. __________________________________________________________________________ Steve Kappel steve.kappel(a)veritas.com VERITAS Software steve.kappel(a)iname.com (Personal)

Re: Extending db file

<color><param>0100,0100,0100</param>Opps . . . . I think I resent my origional message to the list by accident when I was trying to form this reply. If I did, sorry. I did a bunch of testing and found that I could resize a db files up to a maximum size of 1582940k. Up to that point I can resize the db file with no problem. Any attempt to resize a file past this point resulted in the error. Oracle 7.3 has a 2gb file limit so this didn't seem to be an oracle error. By just coping files I was able to create a file over 4gb in size, so the problem didn't seem to be a netapp/nfs problem. I decided to change some mount options. THe first things I tried was running nfs over tcp (I had been using udp). IT WORKED! After making the change I was able to resize the db file right up to Oracle's 2gb limit. I don't know what's different between nfs over tcp and over udp, but it's working now! Rick ></color>I've brought an Oracle db (7.3.4.3) up on a >RS/6k(aix432)/Netapp(534r2) system.

RE: Backing up a filer

Hi Kelly! We are currently using Veritas Netbackup v3.2 with NDMP Extension to backup our 4 Netapp F740. Two Filers have directly attached DLT7000 Drives and the other two are backed up via GBit - LAN with NDMP 3way Backup. (We also use Library Sharing for the the two NDMP-Masters). Throughput is about 15-20GB/h per DLT7000, and we are very pleased with that solution. Currently we are using Veritas Netbackup v3.2 with patch 326, Our Filers have Ontap 5.3.4R2. One Question because I´m new to Netbackup: -NDMP alternate client Restore: Restore Data backuped from Client A directly to Client B? What must I do to make this possible? -NDMP Direct Acces Recovery: Restore of single Files/Directories in a short time (Our Backup Images are currently about 100 - 150GB). What Restore times do you have? (In my case, it looks like the Filersearches the whole dump, which can take up to 8 hours). Is there any possibility to speed this up? Thanks for any answers/ideas. regards, Klaus Micheler Klaus Micheler Infineon Technologies mailto:Klaus.Micheler@infineon.com -----Original Message----- From: Kelly Wyatt Sent: Wednesday, February 09, 2000 1:35 PM To: 'Steve Kappel' Cc: toasters(a)mathworks.com Subject: RE: Backing up a filer Is anyone actually doing 3-way NDMP backups w/ NetBackup. We have been pleased with using NBU with NDMP and directly attached drives for our filers for about 18 months... but, we are about out of capacity in our two tape libraries. Most filers have two tape drives (which we prefer), so when we install the three filers we just received, we have hit our limit... and we have three more filers on order... So, we need to either get another tape library or come up with a solution that doesn't require an entire tape library for every 5 filers. Thanks for any input -- Kelly

Extending db file
by Richard L. Rhodes 12 Feb '00

12 Feb '00

Ok, I'm stumpted! I've brought an Oracle db (7.3.4.3) up on a RS/6k(aix432)/Netapp(534r2) system. The mounts are using nfs v3 and udp. All has gone really well except when I went to extend the size of some of the db files. When I do this I get the following messages: SVRMGR> ALTER DATABASE DATAFILE '/oracledata/orac/dbfiles/orac_gis_1.dbf' RESIZE 1600M; ORA-01237: cannot extend datafile 10 ORA-01110: data file 10: '/oracledata/orac/dbfiles/orac_gis_1.dbf' ORA-09967: sfsfs: unable to resize a file larger The db runs correctly. Oracle has permissions to, and can, create/delete files in this directory. The netapp filesystem isn't out of space - I can (as oracle) create large files in this dir. Snapshots are not using the space. There's no AIX error message. There's no error message in the Netapp messages file. In general . . . . I'm stumpted! Does anyone have any idea of what might be causing this? I highly suspect user error (me) but right now I'm blind as to what I may be doing wrong.

RMA reminder calls
by Jim Harm 10 Feb '00

10 Feb '00

Has anyone else gotten just a little bit miffed at the frequency, speed, and pointlessness of the calls about NetApp RMAs? I get called in less than a week. shipped on 1-31, received on 2-1, reminder(actually more of a where is it, ya dead beat?) call on 2-2!, it is scheduled to be installed today and I don't want the broken box in office; it gets shipped when I have time. sometimes I'll get a call with a list of RMAs from the last 6 months and they expect me to respond with the whereabouts of every RMA when the fact is they have all been shipped back to NetApp. I have to schedule work to replace parts and it takes sometimes a week or more(usually less) and I don't want to have to deal with some extra middle man company to try to justify what I am doing with the RMA. And I feel guilty if I shine them on. }}}===============>> LLNL James E. Harm (Jim); jharm(a)llnl.gov (925) 422-4018 Page: 423-7705x57152

New to Filers
by Andrew Webster 10 Feb '00

10 Feb '00

I have a couple of basic questions:- 1) I cannot see the ~SNAPSHOT directory at the root of each share. The directory is certainly there, but it doesn't appear in the list. I'm using NT 4, IE5, SP6 and the "Show all Hidden Files" turned on. The manual says I should see it, but it isn't there. Am I missing something? 2) When a create shares I sometimes get the "Device or Directory cannot be found" but the directory exists. Should I be using the C:\stuff name or c:\vol\vol0\stuff?

>Do you know what the impact on the filer is? Does the "media server filer" need to have extra CPU capacity or disk capacity? I asked the following of Grant Melvin of Network Appliance: > >This is one thing we are considering: > >Another plan is to have a storagetek with NDMP media servers... say we have the L700 with 20 tape drives, with OnTap 5.3 I can have 5 filers driving those 20 tape drives (two tape adapters per filer, two drives per tape adapter). These are now my "NDMP" media servers. The backups would go across a dedicated GB network. > >So, with NBU 3.2 I can do the filer to filer backups through these filer media servers, right? Yes. A 3-way backup is automatic when you refer to a storage unit on a different NDMP host than the data host. >My question is: what impact is this operation on the filer -- both CPU/disk space needs, etc? What is the minimum filer I could use as these media servers -- little 720's with one shelf/minimal disk? or would this require a beefier filer? There isn't any disk space impact on the tape agent host (at least as far as I am aware). The NDMP server is just moving data from the network to the tape drive. Someone from NetApp would be a better source for what CPU resources would be needed. Note that even if NetBackup supported backup to NBU media servers you would still have the impact - its just moved from a filer to the NetBackup media server. __________________________________________________________________________ Steve Kappel steve.kappel(a)veritas.com VERITAS Software steve.kappel(a)iname.com (Personal)
