Netapp Ontap 6.4.1 and Veritas Netbackup 4.5
by Moshe Linzer 17 Jul '03

17 Jul '03

We recently upgraded our Netapp filers (760 cluster) to 6.4.1 and were surprised to discover that NBU stopped working for incremental NDMP backups. We are able to run full backups successfully. Tried setting the filer to ndmp ver 3, with the same results. Is anybody running NBU with 6.4.1? I would rather avoid the pain of downgrading. Veritas does not officially support 6.4.1 yet (6.4R1D18 is there most recent supported release), so they have not been much help.

RE: Restricting volume access to specific network interfaces
by Alan McLachlan 17 Jul '03

William, Dirk is right, however if all you want to do is host a database on your filer there's no need to spend the money on a Multistore license. I've been doing this for over four years now (long before vfilers/multistore). Just create a dedicated Gigabit Ethernet network segment (seperate switch or port VLAN or simple crossover cable). Create a separate IP range for the dedicated "storage network". Here you can be creative and use jumbo frames (large MTU) if your switch supports it to improve large transfer performance. Because it's a seperate physical network the large frames won't be seen by your routers so you can use them safely. For NFS databases, simply set up a seperate identity in your hosts file for the filer on the storage network and you're done. For CIFS (Windows) things are a little more complicated. If you're using SQL Server 7.0 or 2000, set the trace flag to allow UNC paths ("dbcc traceon 1807"). The only catch is that the UNC path (or mapped drive letter for Sybase/Informix/Oracle) must use the actual dedicated network IP address, not a name or you'll get a "network path not found". Using a LMHOSTS #PRE definition doesn't help here as the issue is the authentication path to the domain controller. (Named paths force a direct DC lookup first to get a token to send with the open file request, IP address paths force the target device to do the lookup itself which is what we need in this case). So, to access your tablespace files the path might be something like "\\192.168.1.100\SQL$\MSSQL\" Certainly the share is still available on both networks - which is what you are trying to avoid, however you use can use the ACL's and hidden shares to reduce or eliminate the risk of user access to the share over the LAN. This approach is recommended in several of the NetApp database integration technical reports available on www.netapp.com regards, Alan McLachlan Senior Systems Engineer Storage Management Solutions ASI Solutions www.asi.com.au Ph +61 2 6230 1566 Fax +61 2 6230 5343 Mobile +61 428 655644 e-mail amclachlan(a)asi.com.au -----Original Message----- From: Dirk Schmiedt [mailto:Dirk.Schmiedt@munich.netsurf.de] Sent: Wednesday, 16 July 2003 9:44 PM To: Holland, William L Cc: 'toasters(a)mathworks.com' Subject: Re: Restricting volume access to specific network interfaces Holland, William L wrote: >Is it possible to restrict access to volumes/qtrees/shares to specific >network interfaces?

You'll have to buy a MultiStore / VFiler license. This will give you the ability to use multiple independent routing tables for different physical and/or virtual network interfaces, named "IP spaces".

Restricting volume access to specific network interfaces
by Holland, William L 16 Jul '03

16 Jul '03

Is it possible to restrict access to volumes/qtrees/shares to specific network interfaces? For instance, I create a volume and/or qtree to host a database. I don't want it to be accessed via the onboard 10/100 connection, instead I only want it to be accessible by a dedicated GbE connection i.e. e4a.

gigabit nfs performance
by Dan OBrien 16 Jul '03

16 Jul '03

What can I expect for Gigabit NFS performance between my F630 NetApps and a pretty hefty Linux box, both running Gigabit network devices? My filer is running: NetApp Release 5.3.6R2: Sat Aug 5 09:40:44 PDT 2000 The Gigabit board is: slot 10: Gigabit Ethernet Controller e10 MAC Address: 00:60:cf:20:2b:2f (1000fx) e10: flags=300043<UP,BROADCAST,RUNNING,TCPCKSUM> mtu 1500 inet 209.41.211.225 netmask 0xffffffc0 broadcast 209.41.211.255 ether 00:60:cf:20:2b:2f (1000fx) I'm using a Transition Networks 1000Base-SX to 1000Base-TX Media converter into a Linksys 2 Gigabit port / 24 100BT port switch. The Linux box is running an Intel e1000 server card e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex All wiring is CAT 5E. I mount the filer on Linux as: mlswna:/ on /backup/mnt/mlswna/rt type nfs (ro,timeo=14,rsize=32768,wsize=32768,nfsvers=3,addr=209.41.211.225) UDP, NFS3, 32K rsize. (Linux TCP NFS support is not quite ready for prime time.) I copied a 100MB file in under 10 seconds. That's around 10Mbytes/second. $ ls -l diskfile -rw-r--r-- 1 34726 34726 104857600 May 9 13:44 diskfile $ time cp diskfile /dev/null 9.85s real 0.00s user 0.31s system $ bs -c 104857600/9.85 10,645,441.6244 I would expect much better than this.

NOTE REPLY TO phillipweah(a)indiatimes.com IF INTERESTED ATT: Liberia,a country in West Africa is presently torn apart by strife and armed rebellion.These upheavals have led to the intervention of the American government which has insisted that the incumbent president Charles Taylor,vacate his position and allow an international peacekeeping force to act as a transitional government. The embattled president Charles Taylor,has been offered political asylum by the Government of the Federal Republic of Nigeria, and he intends to grasp this lifeline that has been provided. The Government of the United States of America have clearly stated their intentions to investigate the finances and financial dealings of president Charles Taylor and have also threatened to freeze his personal accounts.In the light of these circumstances,the president has instructed me,his personal assistant to source for a foreigner who can take possesion and control of a large portion of his personal fortune which he has amassed over the period of his regime, which is stashed away in a financial institution in Europe. These monies amount to approximately four point five million euros (4. 500.000 million euros) Adequate remuneration will be provided for services rendered by you. It is important that you expedite action in this transaction if you are interested, because time is of the essence.Confidentiality is also of great importance. Thankyou Phillip Weah Personal assistant to the president.

virus scan on a network share changes Unix file permissions to 77 7
by Clawson, Simon 11 Jul '03

11 Jul '03

Hi, A user in France has run a virus scan, using NAV 7.5 across a network share to the filer. This resulted in no problems in the PC world, however, the files when viewed from UNIX have a 777 permission set. I tested this on a file on our filer here and did not see this effect. Has anyone else tried this? I know this is not the recommended way to scan the filer, and have advised the user of this.

RE: access same files via SAN and NFS
by Clarke, John L. (CIS) 10 Jul '03

10 Jul '03

Kerry, If its just a regular NetApp (not a SAN Netapp), you can put in a Fibre Channel card into the NetApp and connect it into a "tape backup" SAN so that you can use the SAN to switch in a tape drive to the filer. Very similar to just attaching a fibre-channel or SCSI tape drive directly to the NetApp. You could then use NDMP to back up the filer to the tape drive(s) over the SAN. This assumes that your TSM backup server supports NDMP. Works great for us.
