If you are using a CISCO switch, this may be the cause. You have your media type set to auto. Netapp and Cisco do not negotiate well together. My suggestion would be to force the NIC to full duplex and force the port on the switch also. Also, i have never used 0.0.0.0 to specify "default" before. I am also curious as to what LinkNegotiation does?

We've had the same problem as well with our F740s w/ 100BT. This problem with autonegotiation is neither particular to NetApp nor Cisco. We have SGIs, Suns, and HPs that also have had problems with autonegotiation, and I've heard from others having similar problems with other non-Cisco network devices. The problem is that the autonegotation standard in IEEE (Cl. 28 of IEEE 802.3u, based on NWay scheme) is a bit vague, which results in vendors implementing autonegotiation in such a way that it tends to be incompatible with how other vendors implement it. An unfortunate fact of life. A good into to autonegotiation can be found at: http://cesdis.gsfc.nasa.gov/linux/misc/NWay.html As for using 0.0.0.0 for the default gateway, that should be perfectly acceptable. --john -----Original Message----- From: Dane Jasper [mailto:dane@sonic.net] Sent: Thursday, December 16, 1999 6:48 PM To: John Gaines; Mark D Fowle; toasters Subject: Re: On Thu, Dec 16, 1999 at 03:18:52PM -0600, John Gaines wrote: > If you are using a CISCO switch, this may be the cause.

I've got an Extreme Networks Black Diamond switch, and our F230 won't auto-negotiate 100-BT-fd with that either. Of course, neither will our Cisco 7507. It's ironic that the two more important bits on my network won't negotiate their connection speeds, but lots of irrelevant little workstations will. -- Dane Jasper Sonic.net, Inc.

Thanks for the backup help
by Alan R. White 16 Dec '99

16 Dec '99

Many thanks to all those who responded to my questions about backup. In summary it would seem that if I'm going to have 500GB filesystems then nothing hokey is going to cut it - I need something to either manage a locally attached bunch of tape drives and an autoloader. The only viable alternative seems to be either dumps across rmt (or rsh) or NDMP to a host with a large bunch of tape drives in a larger library. Our enterprise backup product doesn't support any of scenarios yet. I need something cheap and cheerful to manage this for me. The dumps to tape are only for a complete filesystem recovery, we would run snapmirror to keep the users going while rebuilding a broken box. File level stuff I'll handle through a CIFS mount on an NT box where our backup client will run. This leads to 2 questions 1) Which cheap and cheerful product to take care of the dumps and which of the ways above? Remember the dumps are only for volume recovery. 2) Has anyone worked out what the right way to failback after cutting over to a snap mirror replica? I understand netapp are working to make it easier but right now it looks close to unworkable with large volumes of data. If there are clever answers here then would anyone take the risk of not having a volume level dump? TIA, Al

All negotiation is off (both filer and switch) - We did think of that first though.

Fastest way to remove files
by Jeff Krueger 15 Dec '99

15 Dec '99

Does anyone know of a fast, safe way of deleting a large qtree on a NetApp? Has anyone tried the rc_toggle_basic command "rm" from the console? Will it remove files recursively? Do they go into snapshots? Is it a "good thing(tm)" to do? It seems like a waste to do a "rm -rf" over NFS... -- Jeff -- ---------------------------------------------------------------------------- Jeff Krueger E-Mail: jeff(a)qualcomm.com NetApp File Server Lead Phone: 858-651-6709 IT Engineering and Support Fax: 858-651-6627 QUALCOMM, Incorporated Web: www.qualcomm.com

Nfs or CIFS-problem
by Öberg Mats 14 Dec '99

14 Dec '99

Hi, we're currantly experiencing some very annoying problems with our netapp, apparently it's having a hard time mapping cifs-accounts against the nis-accounts. The errors we get are the following: Sun Dec 12 08:18:32 CET [mountd]: yp_next: clnt_call: RPC: Timed out Sun Dec 12 19:02:55 CET [CIFSPasswordCache]: yp_next: clnt_call: RPC: Timed out Mon Dec 13 09:22:18 CET [rc]: CIFS terminated with 255 open files from 1167 CIFS users Mon Dec 13 09:24:23 CET [rc]: CIFS terminate aborted due to a hung CIFS I/O operation. Shutdown the system using halt -d and report this incident to NetApp Anybody know what the problem is? I read a bug report on the now-site saying something about problems with more than 1000 entries in the yp-group-database, could this be it ??? Best regards Mats Oberg TietoEnator

Saves using Legato ClientPak for Netapp
by Scott Mikusko 14 Dec '99

14 Dec '99

Howdy, Question for anyone out there using Legato's Netapp ClientPak. I have installed the client software on an F760 filer and trying to run some backup tests to see how this all works. I have created some test filesystems on the filer, and set a client entry on the Networker server. When I go to run the group that has the filer client, it starts up rather slowly, tell me it's starting to do a full save, then seems to just sit there for ages. I have about 10 savesets configured in the client setup, but the server appears to try to start only a couple savesets one at a time. It doesn't load any tapes, or any other activity. It appears to create the initial db entries, but no savesets start up. Just seems to idle there doing nothing, and repeat the same messages: Dec 13 15:33:16 obsidian root: NetWorker Savegroup: (info) hyades:/vol/vol0/ivpn/system.rt/proxy.cluster no cycles found in media db; doing full save Dec 13 15:36:08 obsidian root: NetWorker Savegroup: (info) hyades:/vol/vol0/ivpn/system.rt/www.cluster no cycles found in media db; doing full save Anyone have any experience with the ClientPak? The tech_dialog at Legato appears to have nothing about this type of error, nor does NOW. I'm opening a ticket with Legato tomorrow (once they sort out my support contract). Any input appreciated. -Scott -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Scott T.

Incremental NDMPcopy problem
by Jeff Krueger 14 Dec '99

14 Dec '99

I'm trying to migrate a 100GB qtree between two filers using NDMPcopy. A full copy worked flawlessly, but I can't seem to get an incremental to work. The restore process keeps complaining that the "restore_symboltable" file doesn't exist, but restore should be creating that file, right? Here's a log of the error: % ndmpcopy crockpot2:/vr_data icemaker:/vr_data -level 5 Connecting to crockpot2. Connecting to icemaker. crockpot2: CONNECT: Connection established. icemaker: CONNECT: Connection established. crockpot2: LOG: DUMP: crockpot2: LOG: creating "/vol/vol0/../snapshot_for_backup.4609" snapshot. crockpot2: LOG: DUMP: crockpot2: LOG: Using Partial Volume Dump crockpot2: LOG: DUMP: crockpot2: LOG: Date of this level 5 dump: Mon Dec 13 11:18:37 1999. crockpot2: LOG: DUMP: crockpot2: LOG: Date of last level 0 dump: Fri Dec 10 11:30:55 1999. crockpot2: LOG: DUMP: crockpot2: LOG: Dumping /vol/vol0/vr_data/ to NDMP connection crockpot2: LOG: DUMP: crockpot2: LOG: mapping (Pass I)[regular files] crockpot2: LOG: DUMP: crockpot2: LOG: mapping (Pass II)[directories] crockpot2: LOG: DUMP: crockpot2: LOG: estimated 378962 tape blocks. crockpot2: LOG: DUMP: crockpot2: LOG: dumping (Pass III) [directories] icemaker: LOG: RESTORE: icemaker: LOG: restore: Cannot open symbol table file /vol/vol0/vr_data/restore_symboltable: No such file or directory icemaker: Connection halted: HALT: Internal error!

negative values from SNMP?
by Darrell Fuhriman 13 Dec '99

13 Dec '99

% snmpget -m ALL -M $PWD -R XXXX public enterprises.789.1.2.2.1.0 enterprises.netapp.netapp1.sysStat.misc.miscNfsOps.0 = -736152675 I have a feeling I shouldn't be seeing something like this. As you can imagine it's screwing up our cricket graphs. :) The filer(s) is running 5.3.2R1. Eventually, it re-wraps and things start working again. Is this a bug with DOT, or the snmp software, which is the UCD package (v4.0.1), or am I just being clueless? Darrell
