RE: Quantum ATL P4000
by John Clear 26 Jun '03

26 Jun '03

I have a dual P4000 NDMP/SCSI hybrid with Legato Networker on a Solaris server. The GigE NDMP drives appear as remote devices in Networker, I assume Netbackup has something similiar. In Networker, you just add a device as 'rd=drive-hostname:/dev/nst0'. Jumbo frames are a must have. We've had our unit for about a year, but just upgraded the switch to one that supports jumbo frames. Backup speed went from 11MB/s without jumbo frames to 18MB/s with jumbo frames. We've been generally happy with it. All enterprise backup sw/hw solutions suck, and this one doesn't suck to badly. John

Quantum ATL P4000
by Holland, William L 26 Jun '03

26 Jun '03

Anyone familiar with this tape library in a GbE/iSCSI environment? I'm particularly interested in knowing how the GbE interfaces are added and managed. Also how well this unit works using Veritas NetBackup on a Win2K server as the master controller and the NDMP option on the Network Appliance filer.

DNS and CIFS win2k ?
by Frank Bonnet 26 Jun '03

26 Jun '03

Hi Anyone knows what to add into my DNS database file to let our filer understand what I want to do ? I use BIND 9.2.2 on a UNIX box, not M$ DNS here is the error message during cifs setup Do you want to modify this name? [no]: CIFS supports three types of user authentication: 1. Windows Domain authentication. 2. Windows Workgroup authentication using the filer's user accounts. 3. /etc/passwd and/or NIS/LDAP based authentication. What type of authentication will this filer use? [1]: 1 The filer will use Windows Domain authentication. Enter the Windows Domain for the filer []:PLONK This seems to be a Windows 2000 domain, but CIFS cannot locate the '_ldap' services for PLONK in DNS. CIFS cannot install as a native Windows 2000 server in this domain until this situation is rectified. If you continue with setup, this filer will attempt to join PLONK as an NT4 server. Do you wish to continue and join PLONK in NT4 mode? [yes]: no CIFS local server is shutting down... CIFS local server has shut down...

ONTAP Simulator available on NOW
by Dave Hitz 26 Jun '03

26 Jun '03

Some of you may know that NetApp Engineering uses an ONTAP Simulator as part of our development process. (The simulator runs all of ONTAP as a process under Linux. At a very low level, we spoof the disk drivers, so that disks are simulated by local files. We spoof the network drivers by putting the Linux Ethernet card into promiscuous mode and creating a fake MAC address associated with the simulator.) Enough technical details. The point of this message is that we are now making the simulator available to customers so that they can experiment with ONTAP features and commands without putting production systems at risk. I have had many customers tell me that they wished they had a way to play with new releases and new features, but they didn't have a safe place to do it. Just to be clear: This is not production software. It's ONTAP running on top of Linux, so don't use it for performance testing. We have no formal support program. Don't call NetApp support. This is an "as is" tool. (Some restrictions may apply. :-) On the other hand, I think you will find the simulator to be very useful for experimenting with ONTAP. Hundreds of NetApp engineers use it every day, and we have been using the simulator for over a year in NetApp training classes. Not only can you experiment with the features of a single filer, but you can run multiple simulators and experiment with features like SnapMirror, SnapVault, and Cluster Fail Over. It doesn't support Fibre Channel, because that would take more hardware, but it does support iSCSI and all of the other TCP/IP protocols, including NFS, CIFS, HTTP and FTP, as well as network management protocols like SNMP and NDMP. Here are some details: You can download the simulator from NOW at <http://now.netapp.com/NOW/cgi-bin/simulator>. We have created a category in the NOW community forums called "ONTAP Simulator" that can be accessed at <http://forums.netapp.com/showcategory.asp?cid=172>. And finally, we have created a majordomo mailing list that people can join at xdl-simulator(a)netapp.com. (You know the drill. To join send to majordomo(a)netapp.com, not to the simulator list itself.) And of course, feel free to talk about it here on toasters. As I said above, the simulator is NOT formally supported, but some volunteers at NetApp have agreed to informally answer questions to the xdl-simulator mailing list. Have fun!

1000Base-SX Gigabit Ethernet cable spec
by Dan OBrien 26 Jun '03

26 Jun '03

Hi, Anyone using their 1000Base-SX Gigabit Ethernet card? (Mine's on an F630.) Is the cable specification for it? SC to SC - Multimode Duplex Fiber Optic Patch Cable. 62.5/125 µm I'm going to purchase a 1000Base-SX to 1000Base-TX converter so that I can hook this old beast up to our copper gigabit switch. The converters are all SC connectors. I have no experience with this fiber optic stuff. The Gigabit card looks like the little square plugs (SC) but I can't find anything in the hardware specs for the F630. There is a lot of discussion about the Fiber Channel cable specs. Any gotchas in my approach? Regards, Dan O'Brien, dmobrien(a)lcsi.net Cell: 614-783-4859 Work: 614-476-8473 Home: 740-927-2178 Pataskala, OH

FW: Slow GbE Network
by Holland, William L 26 Jun '03

Turned out that I had DNS enabled on the filer. Turning DNS off made everything function like it should -- i.e. immediate response from both the server-filer connection and network-filer connection.

AW: ONTAP Simulator available on NOW

I tried to run from a knoppix system, but it seems that the kernel is too new 2.4.20. I'm getting only a segmentation fault. Any trick there or just have to find an older release?

Juni 2003 19:21 To: Merkin, David S; toasters(a)mathworks.com Subject: RE: ONTAP Simulator available on NOW Yes, However, you will need a VMWare extension to Windows XP. To be honest, if you have a spare outdated computer standing around then it is easy to install linux and then to run the simulator on it. You do not need much linux knowledge to get it to work, even if you have never installed linux it should only take a few hours to learn how to install a mininal system that is sufficient for the simulator. This week I installed SuSE 8.0 Profession with minimal system on a Pentium 90 with 48 MB RAM and a 800MB IDE harddisk to be able to run the simulator. This machine is a bit low on memory, but I decided to try it before adding a bit more RAM. But the simulator runs, although with a lot of disk activity due to paging. It might be old and slow, but it is sufficient for me if I want to check something and I believe that it will work good enough if I find some RAM in my junkbox. I also installed a minimal linux on an old AMD K6-2 333Mhz with 128MB and 6 GB Harddisk. This system runs the simulator perfectly without any complaints. The interesting part is that I also installed a minimal linux on a machine with an AMD Duron 1300, 256MB and a fast 40GB harddisk but the performance jump from the AMD K6-2 isn't that noticable. Actually this machine was the most difficult to install due to a problem with the mainboard under linux. If you would like to give it a try then I suggest you join the simulator mailing list where I can help you to get linux to work, but please note: I don't know much about linux, my specialisation is Windows 2000.

I'm working with my salesman on adding a DS14 shelf to my F810 filer. (already have one DS14 shelf) He's put in the quote: 2x NetApp DS14 LS Module, Copper-Copper Ports On my current DS14 shelf I have: 2x NetApp DS14 LS Module Cu-Cu Ports Do I need the Module's on the new shelf? Why do I have two on the current shelf? Steve Evans SDSU Foundation (619) 594-0653

Slow GbE Network
by Holland, William L 25 Jun '03

25 Jun '03

I'm doing some performance testing with an F810 that is connected to our network via the onboard 10/100 NIC. DNS, WINS, etc are configured on that interface. The F810 also has a dual port GbE NIC connected directly to a Win2K server that is also connected via 10/100 to the same network as the F810's onboard 10/100. When I try things such as rsh 192.168.2.1 date it takes a VERY long time to run. Also connecting via unc (e.g. \\192.168.2.1\c$) takes a lot longer than it does over the 10/100 network. I suspect the issue is really on the Win2K side and how it tries to find clients but I am not sure what to look at. Any ideas? Thanks in advance.
