CIFS
by Malek Hamdan 18 Sep '01

18 Sep '01

Hi, I have just installed Data ONTAP 6.1R1 with CIFS support. I am using domain authentication, though I am unable to manage shares or permissions through the server manager. Instead I get an "access denied" message. Can anyone shed some light on what I might be doing wrong?? Kind regards MH

Re: Networker "no output" error?

Try setting the timeout value in the client setup higher - from 30 to 60. I've seen volumes with thousands of small files timeout while Networker "crawled" the directory structure. Bumping the timeout value has ensured successful/complete backups since then. Although I don't recall ever getting the 'no output' error.

NBU sets filer attached drive down
by Hannes Herret 14 Sep '01

14 Sep '01

anyone knows this behaviour? we're running 6.1.1 on F740 w/ an direct attached ATL L200 (1 Drive) Backupserver is an E450 w/ Solaris 8 and NBU 3.4 DC. NBU always sets the drive in the L200 down. Also i'm upping the drive it lasts bout 30 sec. till the drive is down again. no ndmp backup is possible. a started dump from the filer is working fine. the nbu config seems ok. authorization works, robtest and tldtest from the nbu-server on the L200 also works. could this be a problem cause of missing /etc/dumpdates? who can read an "ndmpd debug 50"-output? thx h -- ------------------------------------------------------------------- Hannes Herret IT-Service / Storage phone : +43 (1) 60 126-34 Bacher Systems EDV GmbH fax : +43 (1) 60 126-555 Wienerbergstr. 11B mailto:hh@bacher.at A-1101 Wien, Austria www : http://www.bacher.at/ Europe

RAID checksum revert process
by Jeffrey Krueger 14 Sep '01

14 Sep '01

Okay, after creating 16 volumes on 6.1 machines for snapmirror from 5.3 machines, can I say that there really needs to be a "vol create" option to say "-checksums old". It has been a pain to create all these volumes just to wait for checksum reversion. Installing the filer on 5.3 and upgrading after the initial snapmirror isn't an option either - the destination already has other production volumes - besides, thats a kludge. Beyond that, has anyone else noticed that checksum reversions seem to be "single tasked"? For instance: Thu Sep 13 15:46:17 PDT [reactor: worker_thread:error]: A snapmirror transfer from vol0 to vol0 has found that the two volumes have differing checksum states. Data ONTAP is aborting the snapmirror transfer and reverting the checksum state for the destination volume vol0. After Data ONTAP displays a message showing the revert is complete, you can retry the snapmirror transfer. You can use the vol status -c command to see the progress of the reversion. Thu Sep 13 15:46:31 PDT [reactor: worker_thread:error]: A snapmirror transfer from vol0 to vol2 has found that the two volumes have differing checksum states. Data ONTAP is aborting the snapmirror transfer and reverting the checksum state for the destination volume vol2. After Data ONTAP displays a message showing the revert is complete, you can retry the snapmirror transfer. You can use the vol status -c command to see the progress of the reversion. # rsh reactor vol status -c vol0 Volume Checksum style Checksum status vol0 zoned Checksums reverting (98% done) # rsh reactor vol status -c vol2 Volume Checksum style Checksum status vol2 zoned Checksums reverting (0% done) Just an FYI for other folks - this takes a few hours to complete for each volume when the volumes are ~500GB. -- Jeff
