M2 firmware and NDMP
by Stout, Noelette 21 Mar '02

21 Mar '02

We running F840c filers backing up over NDMP (using NetBackup) to an Exabyte X200 library with Mammoth2 tape drives. We recently received notification from Exabyte that a firmware upgrade is available. We would like to do this upgrade, but do not want to cause any problems with the NDMP backups from the filer. Has anyone done this upgrade or have any insights into this? Thanks, Noelette Stout Unix System Administrator IKON Office Solutions, Inc Digital Express tel.

Hidden Commands?
by Ben Rockwood 21 Mar '02

21 Mar '02

Hello Toasters. Please forgive the stupidity of this post, but I've got to ask. Why is it that commands like, rdfile, do not apper in the OnTap admin guide or the command references? Is this a "taboo" command? OnTap online help (ie: help command) doesn't list it either. How many other commands like this are there, and why isn't it listed among other commands? brockwood(a)homestead-inc.com

or, if running a recent version of ONTAP, you can do cifs sessions -summary from the command line (-summary also works for cifs shares). > -----Original Message----- > From: kevin graham [mailto:kgraham@dotnetdotcom.org] > Sent: Thursday, March 21, 2002 3:38 AM > To: neil lehrer > Cc: toasters > Subject: Re: displaying number of active cifs sessions > > > > > if i want to know how many active sessions there are i do > > Just do an snmpget on: > > enterprises.netapp.netapp1.cifs.cifsInfo.cifsNSessions.0 > (.1.3.6.1.4.1.789.1.7.2.12.0 for the mib-impaired). > > ..kg..

RE: Hidden Commands?

The funny thing is that rdfile is as tame as it gets from a command standpoint, and does not require priv set advance (rc_toggle_basic). I also wonder how many Netapp owners do not know about the "hidden" commands? So, if the intention is to keep us from messing up by using such, maybe they should have used a more complex "secret handshake". --sam -----Original Message----- From: Chris Blackmor [mailto:chris.blackmor@amd.com] Sent: Wednesday, March 20, 2002 2:21 PM To: Mike Horwath Cc: Chris Blackmor; Ben Rockwood; toasters(a)mathworks.com Subject: Re: Hidden Commands? rc_toggle_basic Is that what you are looking for?

RE: SQL I/O error
by Lella Bennett 21 Mar '02

21 Mar '02

As a quick follow-up, I'd like to clarify some of my comments below. First, it is my belief from doing extensive research into this problem that it is a Microsoft problem, not a problem with the functionality of the NetApp filer. Also, Network Appliance does provide a solution to this particular problem using their SnapDrive product. We participated in the beta testing of this product and we believe that it does in fact solve the error 59 problem with SQL Server. However, we have chosen not to implement SnapDrive at our site because of the overhead needed to run snapshots (50% of usable disk space) and in order to realize the increased performance of SnapDrive, we would have to do some extensive network re-engineering that at this time is not cost effective for us to do. Sincerely sorry if I misled anyone regarding our experience.

In fact, this error is the reason we ended up removing our production databases from netapp filers. We've gone round and round with both NetApp and Microsoft on this issue and the bottom line is this: this error is due to the fact that the SQL traffic is going through the TCP/IP stack. Evidently, there is some latency that SQL server experiences while trying to communicate with the data file and the SQL server thinks that it's lost the connection and throws this error, marks the database suspect, etc... The other reason why this error may occur is that you've reached the maximum number of threads available. If this is the case, you will see an error in the NT event log referring to this. You can increase the number of available threads using a reg hack. If it's not caused by the threads issue, then I can't help ya. Like I said we experienced A LOT of pain due to this error and never could find a solution to it.
