LACP and filers
by tmac 27 Mar '07

27 Mar '07

Has anyone successfully configured LACP for channeling of interface to a Cat6500? What is commands are need on the Switch (IOS)? What needs to be done on the filer? I played with this, but was uncertain. Can anyone shed some light? thanks -- --tmac RedHat Certified Engineer #804006984323821 Principal Consultant, RABA Technologies 240-373-3926 (office) 301-688-4705 (Lab) 214-279-3926 (eFAX)

Re: how to obtain patch releases

Mention of patch releases prompts me to vent spleen about the following... If you exercise NOW to fetch ONTAP 7.1.2 you end up at http://now.netapp.com/NOW/download/software/ontap/7.1.2/download.shtml which looks fine until you realise there's no reference to checksums for the files you are about to download. Mystified, I tried 7.1.2P1 instead, which ends one at http://now.netapp.com/NOW/download/software/ontap/7.1.2P1/download.cgi which has the expected link to a checksum page. So although I didn't need any of the fixes in the P1 version, I decide to use that instead. Later, it occurred to me to look at http://now.netapp.com/NOW/download/software/ontap/7.1.2/download.cgi which does have a link to the checksums for the 7.1.2 files. But by then, it was too late ... [In case you are wondering, I am not avoiding 7.2.x because of the problems described by various toaster-posters, but because I am stuck with an F800 series filer.] -- Chris Thompson Email: cet1(a)cam.ac.uk

RE: Drive cleaning
by Todd Kofchur 27 Mar '07

" Now, LTO technology has a variable speed head which speeds up and slows down relative to the speed of the tape passing it. This removes the shoe-shine affect seen in DLT drives." This does not completely remove the possibility of shoe-shine. All tape drives must maintain a minimal speed to write data to the tape and they will NOT be able to go below this threshold. If your network is slower than this minimal threshold you will get shoe-shining even with variable speed heads. __________________________ Todd Kofchur President Penaria Technologies, Inc.

They are a fixed length of tape which is used to calibrate the gearing of drives when an error occurs. For instance, a DLT drive needs it's head spin speed to be synchronised with the speed that the tape passes it as the tape needs to move at a constant speed. If too many errors occur, a DLT drive will ask to be "cleaned". Now, LTO technology has a variable speed head which speeds up and slows down relative to the speed of the tape passing it. This removes the shoe-shine affect seen in DLT drives. I have never seen an LTO drive require "cleaning" as they tend to always be in sync. Take from this what you will, but I'd rather use the space in the library for data. If an LTO drive asks for cleaning, it has issues!!!

how to obtain patch releases
by J. Greg Mackinnon 27 Mar '07

27 Mar '07

We currently are running OnTap 7.2.0 and not having fun with it. 7.2.1 contains many important fixes, but 7.2.1P1 has some critical fixes as well. I am getting fed up waiting for the next GA release, and I am willing to take the risk of running a patch build. The only problem... I cannot figure out how to download it! In the past I have found patch release download links in the NOW KB when referencing a related bug number... not so this time. Anyone know how to get the binaries? Open a support case? Bribe a NetApp tech? Thanks, -Greg Mackinnon University of Vermont

RE: Drive cleaning
by Paul Keating 27 Mar '07

27 Mar '07

The STK libraries only require them if you're using library based cleaning. If you're using tape alert, or otherwise using Netbackup controlled cleaning, you can make any tape ID a cleaning tape......then using "CLN" labels is only a Really Good Idea (TM). Also, Tape alert does not work (or didn't, last I heard) for Filer attached drives. Any tape drives connected to an NDMP device must be cleaned manually, or on a "frequency based" schedule, as the NDMP devices do not know what to do with the received tape alert message, like a Netbackup media server would. You could use Library based cleaning, but that must be turned on for all drives in the Libary, and frequently causes problems with Netbackup. Now back to your problem. If the media were "discovered" by Netbackup, and they didn't have a barcode rule defined for them, they were probably placed in the "DEFAULT" media type, which is probably HCART3. In that case, you need to change the cleaning tapes to media type "HC3_CLN", and make sure the "number of cleanings remaining" is set to a value higher than 0, Volume Pool is set to "None". However it is much easier to define your cleaning tapes before you inventory the robot, as you can't change the media type in the GUI for an assigned media cart.

Th library is licensed for 82 slots. 80 of them have LTO3 tapes 2 of them are cleaning tapes I run the auto-configure on Veritas. It picks up the library on all three filers, only uses the library on one (as expected). It sees three paths to each of the tape drives (also as expected) The inventory scans all the media and sees 82 tapes. I tell it ID 99 & 100 are the cleaning tapes. I can create policies and backup without any problems. Veritas NBU 6.0 (and MP2, MP3 & MP4) has a problem trying to clean the tape drives. When I try to manually clean one I get the following: (96) unable to allocate new media for backup, storage unit has none available Detailed status: requesting resource IBM.ULTRIUM-TD3:001:__ANY__ Error nbjm (pid=22634) NBU status: 96, EMM status: No media is available unable to allocate new media for backup, storage unit has none available (96) Every time, it is the same.

ISCSI Issue and VMWare ESX 3.0.1
by Justin Brodley 22 Mar '07

22 Mar '07

I'm currently dealing with a problem on several of our ESX IBM LS21 Blades when trying to attach to ISCSI Luns on the Netapp FAS 3020's. Our Netapp currently connects to two separate physical networks to deliver ISCSI connectivity. The ESX support folks are telling us that the netapp presents both ISCSI interfaces to the server. Initially the ESX box connects on the correct interface, but then after a few hours it attempts to try the other IP address and fails and disconnects the entire VM Host from the Netapp, despite the fact that the network never went down. We have several Windows 2003 servers with ISCSI initiator that don't have this problem on identical hardware and chassis. I assume that either ESX's iscsi initiator is badly designed, or MS has broken some industry standard spec. To rearchitect our storage network will take significant investment on our part, and we'd rather come up with a way to fix this either by pushing on ESX to fix the initiator or finding a way to have the Netapp only send one IP address back to the initiator. Is there any way to resolve this from the Netapp perspective? Thanks in advance. -Justin

Vol copy will copy a volume's contents and the snapshots as well, but it won't work between traditional and flexible volumes. Since you have space for both the traditional volumes and the aggregates, could you just not migrate the volumes contents to the new volumes and start snapshotting there, and at the same time retain the old volumes for a period of time until you don't require the old snapshots anymore.

List, We have a FAS270 recently upgraded to 7.0.5. We would like migrate from traditional volumes to flexible volumes and keep the existing snapshots. I searched the NOW site and could not find much, has anyone done this? Will we be able to retain the existing snapshots?? We have enough drives to have the aggregate and traditional volumes working simultaneously on the same filer. Cheers. Tom.
