Slow CIFS Write Performance
by Lim, Weng Kiam 30 Nov '01

30 Nov '01

Hi All, I am in the process for migrating user home directories from the current PDC to the filer. Copying 4GB of data took 4 hours to complete. Both the filer and the server running on Gigabit interface. Search the archive and there was suggestion on the smb block negotiation. Any other hints to troubleshoot would be greatly appreciated. Filer - F740 with 1000sx interface PDC Server - Compaq ML530, 2 Xeon 1GHz Processor, 1128 MB of RAM, Gigabit Network Card TIA Weng-Kiam Lim

Re: Performance issue
by Don.Hickey＠alcatel.com 30 Nov '01

I spent most of October with netapp on this one. For me, it was fixed in 6.1.1R2. I suggest you upgrade. See bug id 54265. Don "Haber, David J." <David.Haber(a)vtmednet.org> Sent by: owner-toasters(a)mathworks.com 2001-11-27 07:11 AM To: toasters(a)mathworks.com cc: Subject: Performance issue Has anyone seen intermittent problems when users try to save Excel or Powerpoint files to a share on the filer? Also, what are some of the strategies for dealing with oplock break timeout issues? I've been working with NetApp support on these issues but I'd like other opinions. I'm running an 820 filer, DATAOntap 6.1.1r1, and I have a 4-port, 10/100 full duplex vif.

I do not know any other list than this (mailto:bigbackup@lists.cc.neu.edu) one, but as said above it's quiet here. rgds, Yann

Best place to buy NetApp HW?
by Wollermann, Brian 29 Nov '01

29 Nov '01

My company is looking to buy more NetApp hardware and our local vendor (the only one) does not seem to be giving us very good pricing. My boss wants me to see if there are other vendors that can get us the same thing cheaper. If anyone has a particular vendor that they feel gives good prices can you send me their name and number (US only please)? I would appreciate it. Thank you.

Test lab configs
by Joe Luchtenberg 29 Nov '01

29 Nov '01

I apologize in advance for such an open-ended question. Also, I recognize that this subject is probably as much art as it is science. Nonetheless, I would appreciate any insight that can be offered. I am looking for guidance on the subject of test lab requirements. Specifically, if an organization has multiple filer models in production, is it sufficient to maintain a single filer model in the lab for testing? More generally, can anyone point me to resources on the general subject of designing a data center test lab? A cursory search of the web was not helpful (probably because I am having some difficulty adequately refining my searches). Jeff Browning's paper (TR3055 Creating a UNIX-based Database Software Testing Environment Using a NetApp Filer, http://www.netapp.com/tech_library/3055.html) is instructive from a software testing perspective. I'm interested not only in that, but also h/w and s/w compatibility/interoperability testing, as well as performance testing. Thanks in advance. Again I apologize for the lack of detail in my request. Joe Joe Luchtenberg Dataline, Inc. 757-858-0600 757-285-1223 (mobile) 757-858-0606 (fax) joe.luchtenberg(a)data-line.com www.data-line.com

subst cmd problem - more
by neil lehrer 28 Nov '01

28 Nov '01

toaster folk, mark muhlestein was gracious enough to read my pktt traces. it seems eventhough i am pointing directly to a dir with subst: subst h: \\filer\users\a\adam the command tries to get attribs from \\filer\users\a. so eventhough i had cifs.bypass_traverse_checking on and even an X perm on \\filer\users\a subst got mad. putting some level of read on \\filer\users\a seems to correct it. subst h: \\filer\users\a\adam then works. right now i have R,X on it. any comments? thanks -- regards

nt subst cmd
by neil lehrer 28 Nov '01

28 Nov '01

hi, our homedir structure is /vol/vol0/users/a/adam we want to use the subst cmd instead of 'net use' because we go below the share. and since we have the first letter of the userid in there we can't use the ontap homedir option. however, we can't get subst to work as a user. C:\WINNTSRV>subst q: \\filer\u7\k\kusr1 Path not found - \\filer\u7\k\kusr1 subst works fine as admin. u7 is an ntfs qtree. kusr1 has full control over its dir. cifs.bypass_traverse_checking on is set. i also gave kusr X rights on u7 and u7\k. no diff. filer is 760 with ontap 6.1.1r2. volume is unix style. anybody ever get this to work? any suggestions? thanks. -- regards

Purging classified files from F840
by pkeim(contr-ird) 28 Nov '01

28 Nov '01

I need some assistance in tracking down a specific question concerning our new F840 with release 6.1.1R2. When it's introduced into our production environment next month, it will operate in an unclassified (but sensitive) environment. If a user inadvertently saved a document classified "secret" to the filer, what is the DoD-approved method to completely wipe the file from the volume? Thanks in advance for the help!
