by Jen Hamilton 29 Jun '00

Are disks re-useable? Or are they one-time only? Thanks, Jen Hamilton

RE: FilerA:vol1 -> FilerB:vol0
by Jason.Cody＠netapp.com 29 Jun '00

No, you won't have to issue the download command becuase you are simply putting an "extra" set of files on those "vol1" disks. You are not actually upgrading the OS of the filer that those disks are attached.

RE: HVD or LVD scsi connector?
by MBrookes＠netapp.com 29 Jun '00

Brian, The F/W/D SCSI connector on the back of the your F760 is high voltage, but I'm curious why you need to connect a dedicated machine to the media changer. I'f you're not using an NDMP compliant backup package, you might like to take a look at the NDMP tools on NOW. Regards, Matt. -----Original Message----- From: Brian Hostetter [mailto:BrianH@dice.com] Sent: 29 June 2000 16:25 To: toasters(a)mathworks.com Subject: HVD or LVD scsi connector? Is the scsi connecter on the back of a 760 LVD or HVD? I am trying to hook a tape drive up and need to get a controller for a Linux box that will talk the same language as my netapps. I need this controller to control the media changer of the jukebox. --Brian

Brian, It's not so much the NetApp and the Linux box that need to be compatible - the filer will connect to the tape drive *only*, and the Linux box to the media changer *only* - they are separate busses (of course, it's likely that the library will have the same (HVD or LVD) interface for both the library and the drive). Since the filer's SCSI port is fast/wide/diff HVD, then the tape drive will need to have the same. If you use NDMP-compliant backup software, then you can connect the media changer as well as the tape drive directly to the NetApp filer.

Re: weirdness with our Netapp F760 and DLT tape drive
by Rob Worman 29 Jun '00

Just as an update: -recall that our current testing has removed any Netbackup or robotics from the picture. It's just a Netapp, a SCSI card, and a DLT drive. :) -I'm indeed certain that we're talking about 100% differential SCSI. -I thought I found the problem when I realized that the DLT drive had a SCSI ID of 1. So I set it to 0, rebooted the filer, power cycled the DLT, and saw no difference :( -I have heard from lots of people who aren't having any problems connecting an F760 to a DLT 7k in an STK 9740, so I know it's not some sort of inherent STK-NetApp incompatibility. But I'm reduced, at this point, to finding any possible difference between the SUN drive (that worked) and the STK drive (that doesn't work) - jumpers, firmware, etc. Thanks for the assistance so far, folks. rob __________________________________________________ Do You Yahoo!?

RE: FilerA:vol1 -> FilerB:vol0
by Aaron.Sims＠netapp.com 29 Jun '00

If vol1 on filerA is marked as "root" (use 'vol status' to determine this), then you can remove that shelf from filerA and put it on filerB. FilerB will boot this easily. Once that volume is on filerB, you can do a 'vol rename vol1 vol0' to rename the volume. Of course, this will change what your /etc/exports file will look like. If vol1 is not marked as the root volume, you can still move the disks, but you'll need to boot off floppys and chose the 5 option and issue a 'vol options vol1 root' command. (Or something like that... I don't have a filer handy at the moment to verify) Hope that helps. Aaron > -----Original Message----- > From: Todd C.

FilerA:vol1 -> FilerB:vol0
by Todd C. Merrill 29 Jun '00

I have a populated shelf of disks (one RAID group, one filesystem, one full shelf of 7 disks) that is vol1 on Filer A. I want to put it on Filer B, which currently has no disk. Can I do this without wiping the data on those disks, which I need? How do I get the boot and system files on it without destroying the existing volume and filesystem? Until next time...

two jukeboxes on one machine
by Jay Orr 28 Jun '00

28 Jun '00

Hey all, got another possiably off topic question... In looking for new backup software, we are having to pay quite a premium for having two jukeboxes hanging off of different machines. I was wondering if anyone knows if a Sparc 20 can handle two DLT 8000 jukeboxes hanging off it doing backups, or if I'd need a better machine? I know I should ask sun, but it's not easy to get an answer from them sometimes - I was wondering if anyone had had similar experiences or knowledge about this.. ----------- Jay Orr Systems Administrator Fujitsu Nexion Inc.

Re: weirdness with our Netapp F760 and DLT tape drive

When the drive is DOWN in volume manager (using "vmoprcmd -d" to see state and "vmoprcmd -down N" to mark drive N as down), you can use robtest (which invokes tldtest). From the description it doesn't sound like a problem with robot control. It sounds like a drive problem. The only thing that the tldtest can do with the drive is unload it. -Steve >Date: Wed, 28 Jun 2000 00:19:48 -0700 (PDT) >From: Eyal Traitel <etraitel(a)yahoo.com> >Subject: Re: weirdness with our Netapp F760 and DLT tape drive >To: rob(a)colltech.com, toasters(a)mathworks.com > >Rob, > >Maybe irrlevant, but anyway - >Have you controlled the tape library using "ndmputil" >or Veritas's robot-handling utility (forgot its name) >? > >>From what I know, you need to manually use these >utilities to choose tape and load it to correct drive. > > >Eyal. > > > >--- Rob Worman <rworman(a)yahoo.com> wrote: >> We have a Netapp filer (F760) that we are trying to >> back up (with Veritas Netbackup, but that's not >> really >> relevant to this question) by way of a >> directly-connected DLT 7000 tape drive in a >> StorageTek >> 9740 tape >> library. >> >> We aren't trying to get the netapp to manage the >> robotic tape handling, we just want to write to the >> tape that's been manually loaded into the drive.
