SNMP, mrtg, queries
by Mark D Simmons 24 Apr '98

24 Apr '98

I feel a little dumb to be asking this but how does one actually get the NetApp MIB into mrtg to be able to query and plot information about one's filers? Currently I'm under the impression that I need to convert the fine NetApp MIB in ASN.1 to the serialised integer format, to build into the mrtg script. Now after much searching and thinking I've found a number of BER compilers that'll do the job, outputting C/C++ tables, but nothing that just outputs simple ascii strings. Am I on the right track? Is there a cunning and clever way to do the job without these steps? Has anyone done this before AND are willing to help me out/contrib the work back to the mrtg site? Any and all help sincerely appreciated!

chs/mtx
by Kelly Setzer 23 Apr '98

23 Apr '98

This is not directly on-topic, but considering the discussion lately... I am trying to find a utility like chs or mtx that will work under solaris 2 with an ATL P1000. I've had partial success with chs - it will move the robotics and move tapes from slot to slot, but will move a tape from a slot to a drive. 'mtx' is a product of Automated Network Technologies (anthill.com), which has apparently been acquired by Qualix Group. I've not been successful in finding 'mtx', and Qualix does not seem to know anything...grrr. Any info or other options? thanks, Kelly -- Kelly Setzer <setzer(a)telalink.net> The Telalink Corporation (615) 321-9100 x237 Fax: (615) 321-9110

Re: Budtool to backup netapp

We've been using BudTool to backup our F330 for about 5 months. We spent a month or two working the kinks out of it before we let it touch our filer. Here's what we found: 1) BudTool's reporting is horrible. End of story. Anyone who tells you otherwise is either deranged or hasn't actually used the product. Fortunately, if you know Perl, writing a script to parse the logfile and send out a readable report (and page on fatal errors) is fairly trivial. 2) BudTool's built in scheduling could only have been written by a fool who liked GUIs and never actually had to support a backup solution in a production environment. cron and a small shell script handled this problem. (AMANDA has the best backup scheduling in my opinion. Someday there'll be a vendor who picks up on it.) 3) User level restores aren't supported for NDMP and only work for UNIX clients if your willing to throw security out the window. When doing a restore via NDMP, the destination for the restore has to be on a filer. If your users need to be able to restore data from tape, pick another product. If you're willing to pull stuff off tape for them (the GUIs not bad, but not great either) occasionally, then you'll be ok. 4) Having one BudTool server control a directly connected 100 tape DLT400 jukebox, a 5 tape stacker connected to our F330, and a 5 tape stacker connected to our research departments number cruncher is pretty nifty. Having all the tape and file histories in one place is nice too. 5) BudTool has a utility called btcp which will copy all your most current backup requests (Lev 0s and all necessary incrementals) to a set of tapes for offsite storage. It doesn't just dd a bunch of tapes. Very nice. Unfortunately, btcp is a little brain-dead and tries to copy _all_ the requests to one set of tapes. If you have a couple hundred GB worth of backups, this can take a really long time. Again, a little shell script fixed this problem. All in all, I don't think I've ever been 100% satisfied with any software product. But BudTool gets the job done (with a little help). jason --- Jason D.

reboot of TLU -> reboot of fileserver
by Menachem Kaiser 23 Apr '98

23 Apr '98

Hi, I wanted to check out the following issue that was brought up in one of the responses to my poll (still waiting for more replies): When a TLU (tape Library Unit) is directly attached to a fileserver, does every reboot of the TLU necesarily mean you must reboot the fileserver? OR Is this only specific to the TLU vendor ( as suggested below). I see this as a serious issue!! I don't want the uptime of my fileserver to be affected by something like this.

If the stacker/jukebox hangs for whatever reason (robotic arm, etc), and you need to power-cycle the tape device, you cannot do so with the filer on. You run the risk of frying the scsi bus. Now, it could be that the problems I had were related to the specific DLT stacker (an ADIC vls library) we used. I don't know. I have not risked that sort of problem any more.

It's not prohibitively expensive. The cost of the tape-monkey is amortised over the 100's of other systems he also tends. Don't forget the media costs 300quid/night for a 6dayx13 wk cycle... about 4 times the tape drive cost itself. > > BTW, my english parser keeps croaking over that CIFS statement..

I'm not sure what filer and tape hardware > you have, but you think you need 128MByte/second throughput??!? In my dreams. As I've said before though, in utter seriousness I *do* want to be able to back up 400GB in about 6 hours. 400GB is 6 hours is 19MB/s sustained. Only atm and Gb-ether can provide that over the network. Locally two F/W SCSI channels will provide it happily.
