DECRU FTP ACCESS BUG?
by Milazzo Giacomo 06 Oct '08

06 Oct '08

Hi all A customer of mine asked me to set up ftp access on his E-Series cluster already acting as NFS NAS. OS is 3.1.1.1 I've followed instructions and it seems to work but there's a strange thing and something not clear. Once created the volume, exported, created virtual share, added the cryptainer I've enabled the ftp this way: >vip set -ftp-access on vnetapp1 In the guy I've created a user on the share called ftplogger with password and then I've set up his home directory this way >user home set ftplogger@app_domain rmrcrsdec-01:/vol/ciscolog (the domain has internal users only, no NIS or other external sources) Last I've enabled two hosts for test purposes, the first enabling both read and write and the other one only read (using the IP access functionality) What I've noted is that I can log on Decru using any username and password!!! My rights depend only from the IP. So that I can open a r/w ftp connection from the enabled IP address also using johndoe as user and any password!!! (I got this because once I was sure to wrong to input the password and I expected some 'access denied'...instead I log in!) FTP home dir seems to work fine, once logged user is pointed in the right share and if he tried to change he got access denied but if I perform the command: >user home list I can always read root@app_domain as user using rmrcrsdec-01:/vol/ciscolog and not the ftplogger user created.

san thin provisioning best practices doc
by Nicholas Bernstein 02 Oct '08

02 Oct '08

I'm looking for a good best practices doc I can point students to as a takeaway on using a fractional reserve with luns. Could anyone point me to a good doc? I looked on the now site and the best thing I came across was tr3483, but that just talks about how the process works as opposed to taking about best practices. Thanks, Nick -- Nicholas Bernstein Technologist, Consultant, Instructor http://nicholasbernstein.com

Operations Manager Options on FAS devices
by Jimmy Corncrake 02 Oct '08

02 Oct '08

Greetings all, Though FilerView we can set a number of Operations Manager options under the 'Operations Manager[image: Right]Access' tabs. These options include, *Operations Manager Links: **DataFabric Manager server:* *DataFabric Manager Protocol:* *DataFabric Manager Port:* ** I would like to set these options on the CLI but after looking and looking I can not find which command \option etc contains these. Anyone know? Perhaps it something I need to push from Operations Manager but this would surprise me somewhat. rgds, Jimmy

Sure thing, Jeremy. I talked to NetApp engineering (the networking group). I was doing my homework prepping for my VMWorld breakout session,ran across that note and said "That can't be right"...so I checked with engineering. They said the docs wil be fixed. Share and enjoy!

Hi I had previously checked on this and the second bullet is incorrect. LACP _is_ supported with 10GbE TOE cards. Share and enjoy!

Hi all... i dont know whether its the right forum to ask...but has anyone worked with DECRU FC-series integration with FAS6040... I have configured two FC-520 as a cluster...and added FAS6040 LUNs to the cluster storage... but when i try to present cryptainers to Solaris10 hosts...the host is unable to format the cryptainers (LUNs)...after partioning once i try to label the disk...it says...'CURRENT DISK IS UNNFORMATTED'.... Non-cryptainer LUNs on the same host work perfect.... Any ideas...suggessions...solutions...documentation reference???? thanx...
