I-D ACTION:draft-ietf-nfsv4-05.txt (fwd)
by beepy＠netapp.com 09 Feb '00

09 Feb '00

Not really NetApp related - just NFS related. I meant to send this note out a long time ago. One thing the IETF would like is "user" review of Internet drafts. The working group is moving towards a Proposed Standard over the next few months, which includes review by a wider audience of the standard. You don't have to be an "IETF member" or attend "IETF mtgs" to review. If you're interested, take a look at the latest draft. It is the culmination of a lot of work originally by Sun in the form of a strawman proposal, and later one of our engineers, an engineer from HCL, Sun engineers to form the current specification. This one has been reviewed extensively by the far flung working group - mostly through the e-mail alias. Comments to the working group alias are best. Clarifications and questions to me if you like. beepy P.S. Hi everyone - I've been quiet a long time. ----- Forwarded message from Internet-Drafts(a)ietf.org ----- >From Internet-Drafts(a)ietf.org Wed Feb 9 08:45:42 2000 Message-Id: <200002091641.LAA09977(a)ietf.org> To: IETF-Announce: ; Cc: nfsv4-wg(a)sunroof.eng.sun.com From: Internet-Drafts(a)ietf.org Reply-to: Internet-Drafts(a)ietf.org Subject: I-D ACTION:draft-ietf-nfsv4-05.txt Date: Wed, 09 Feb 2000 11:41:38 -0500 Sender: owner-dl-nfsv4-engr(a)netapp.com Precedence: bulk A New Internet-Draft is available from the on-line Internet-Drafts directories.

Robinson, R. Thurlow Filename : draft-ietf-nfsv4-05.txt Pages : 249 Date : 08-Feb-00 NFS version 4 is a distributed file system protocol which owes heritage to NFS protocol versions 2 [RFC1094] and 3 [RFC1813]. Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the mount protocol. In addition, support for strong security (and its negotiation), compound operations, client caching, and internationalization have been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment.

RE: Backing up a filer
by Steve Kappel 09 Feb '00

09 Feb '00

NetBackup does not support backing up NDMP hosts to NetBackup media server tape drives. Since you have more than one filer, I would recommend selecting a subset to have locally attached drives (possibly part of a shared library). Then use 3-way NDMP to backup filers without drives. Note that 3-way is new in NBU 3.2. >From: Kelly Wyatt <Kelly.Wyatt(a)sas.com> >To: "'Roth, William'" <William.Roth(a)netapp.com>, "'gwong(a)futureshop.com'" <gwong(a)futureshop.com> >Cc: "'toasters(a)mathworks.com'" <toasters(a)mathworks.com> >Subject: RE: Backing up a filer >Date: Wed, 9 Feb 2000 10:16:10 -0500 > >Bummer...

RE: Backing up a filer
by Roth, William 09 Feb '00

09 Feb '00

Greg, The comments in my earlier email with regards to VERITAS NetBackup, NDMP and filers remains correct. Technote 3066 (#4 below) works as long as the NDMP compliant third party backup software supports it. VERITAS NetBackup does not currently (to the best of my knowledge) support performing an NDMP backup from a filer with data going to the Solaris or NT backup server with locally attached tape devices. Call me on 408-822-3308 if there are any questions, or you want to discuss this further. A recent Network Appliance press release details plans to address the idle tape drive issue. It is well understood that direct attached, dedicated tape devices sit idle most of the time. The release can be found at: http://biz.yahoo.com/bw/000202/ca_multive_1.html I'm interested in the proposed NDMP backup testing with a dedicated GB ethernet network. What are the configuration details, when is testing scheduled to start? Thanks, Bill Roth -----Original Message----- From: [ISS] Veritas-Users [mailto:Veritas-Users@wnt.sas.com] Sent: Wednesday, February 09, 2000 6:54 AM To: 'Roth, William'; 'gwong(a)futureshop.com' Cc: 'toasters(a)mathworks.com' Subject: RE: Backing up a filer I understand that you can do NDMP dump across the network to a media server... it is even mentioned in technote 3066, section 4.3 (# 4 below): ---- The NDMP protocol specification allows the following backup configurations: 1. Local backup from a filer to a SCSI-attached tape device 2. Three-way backup from a filer via the network to another filer with a local tape device 3. Backup from a UNIX or Windows NT server via the network to a NetApp filer with a local tape device 4. Backup from a NetApp filer via the network to a UNIX or Windows NT backup server with a local tape device ---- We currently backup filers via dedicated directly attached tape drives (using Veritas NetBackup)... but, this is a costly solution because the tape drives are idle probably 75% of the time. We will be testing NDMP across a dedicated GB ethernet network in the near future. Even if we see some decrease in backup throughput, it will good if we can get those 20 dedicated DLT7000 tape drives in S'Tek 9710's doing more work for us... Is anyone already using a private network and NDMP to backup a filer?

You can dedicate one or more drives from an existing library controlled by NetBackup, or you can attach a new/different library to the filer(yes, the filer does support a locally attached library). Either the NetBackup host (NDMP client) or the filer can be direct connected to the robotic portion of the library(assuming the library has individual scsi ports for the connection). In the end, NetBackup ends up controlling the library either way. If the robot is direct connected to the NetBackup host via scsi, NetBackup controls it. If the robot is connected to the filer via scsi, the NetBackup host sends scsi cdb's via NDMP to the robot through the filer, thus the robot is still controller by NetBackup. What other information or assistance do you require?

We have an F720 on site that isn't doing much since we aren't backing it up. I need some options on how to do this. We currently back up our other systems vith Veritas Netbackup and a tape library. Now, my question(s) is if I want to use Veritas to back up the filer using NDMP, do I have to dedicate a drive on the remote tape library to the filer? Will the filer support a locally attached library, and if it does, does Veritas control the library or does the filer? Thanks for your help Greg

Bummer... I just tried a backup from a filer to the master's locally attached drive and got an errro 154 -- storage unit characteristics mismatched to request. This is w/ NetBackup 3.1.1, and from reading my NBU 3.2 manuals, it does not look like this will work (because the sun is not an "NDMP host" and I have not seen in the doc how to make it one).

Problems dumping onto 2 tapes using F500 and Adic DLT4000
by Simon Butcher 09 Feb '00

09 Feb '00

I have recently begun to require 2 tapes for my backups. However, if I load the tapes into the slots in my DLT4000 (which sysconfig tells me is a FastStor DLT & mt -f rst0a status gives me Digial DLT4000) and do a "dump 0uf urst0a,urst0a /vol/vol0" it appears to work (dumping tape 1 then dumping tape 2) but when i try to restore (with the t option) i find it hasn't touched the second tape at all, but has overwritten the tape 1 with tape 2 data. Any ideas? sysconfig -t doesn't give me the option for rst1a Also the tapes never physically eject, they just go 'offline' Cheers, SB ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Re: RMA reminder calls ( a new wrinkle )
by Bruce Sterling Woodcock 08 Feb '00

Yeah, the disks are understandable, and many of the rest are not really broken parts but rather attempts by NTAP to troubleshoot a particular problem (hardware, software, or external). I find the power supply and fan assembly problems to be very bizarre, and guess you are either cursed or don't have the controlled enviornment you think you have. As to the EOL issues, I agree; NTAP should not EOL products as quickly as they do. I would like to see 4+ years going forward. Of course, as a shareholder, I realize this will cut into earnings.

Pipe trouble
by Ronan Mullally 08 Feb '00

08 Feb '00

I'm having trouble creating a named pipe on a filesystem mounted from a 760 to a Linux system. The 760 is running 5.3.4R3. 'mknod <name> p' gives me a zero-length file rather than a named pipe: # mknod initctl p # ls -la initctl -rw-r--r-- 1 root root 0 Feb 8 15:58 initctl ^ I'm sure this *used* to work (way back when I had a 540). It works fine if I try it on a filesystem mounted from a Linux server... Any ideas? -Ronan
