RE: Solaris iSCSI initiator

Think $500 per TOE and a $200 Linksys gigE switch, versus $1500+ per HBA and a $20,000 Brocade. Yeah, the iSCSI's a little bit cheaper. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Jerry Sent: Wednesday, October 22, 2003 10:30 AM To: Ting, James Cc: list toasters Subject: RE: Solaris iSCSI initiator Wow. this is cool.

Solaris iSCSI initiator
by Jerry 22 Oct '03

22 Oct '03

I've been testing iSCSI on windows systems and the performance/reliability seems to be good. I was wondering if anyone knows why Solaris, or any of the commercial unix vendors haven't jumped on board with this. I noticed a cisco initiator for Solaris, but I wonder if it even works with the netapp. If you call Sun, they are kinda clueless on iSCSI and don't really elaborate much in my experience. This is especially annoying since I notice linux has some iscsi stuff. Any thoughts? __________________________________ Do you Yahoo!? The New Yahoo!

Direct connect Xover performance
by Robert Borowicz 22 Oct '03

22 Oct '03

I've just completed a direct connect private network connection between a Sun Fire V880 and my Filer FAS 940 for running Oracle over. I used the Sun Fire's 10/100 Copper and told the Filer to use FD/100. I've still got to verify the Sun "negotiated" appropriated with the Filer's NIC. What is your favorite rip snortin performance test writing to a Filer mount? I ran a ufsudmp of /usr and here are the numbers I was getting in sysstat.

RE: ndmp phase 1 very slow

This problem is a bug in Ontap 6.4 and it is solved with Ontap 6.4.2P4. We also have the problem by upgrading from 6.3.1 to 6.4.2.

Manually failing disks
by Robert Borowicz 22 Oct '03

22 Oct '03

Is there an issue with manually failing disks on say an unused Volume for testing purposes? IE: I want to test my spare disks and also observe volume rebuild time. If I manually fail a disk I remember that NetApp disks store their failure data. Do I risk maxing out an internal "number of failures" register on the disks if I manually fail a disk several times?

CIFS/NFS file sharing in a non NIS environment
by Clawson, Simon 22 Oct '03

22 Oct '03

Hi, I have a filer with CIFS and NFS licenses. I want to share UNIX style qtrees on PC and UNIX. Currently, if a qtree has UNIX style permissions it will not allow the PC user to open a share. If the qtree has NTFS permissions it will not allow UNIX users to access the share. I have a set-up in my own office where we have NIS, and this handles the name resolution. However, the office I am in currently does not have NIS. I have tried createing a password and group file on the filer, identical to the password files used on the UNIX systems, however this has no effect. Any ideas?

Can a filer do this?
by Greg Wilson 22 Oct '03

22 Oct '03

Hi Does anyone know if it is possible to see what files are being access on the filer from the filers side ?? eg.. run command on the filer for 'n' minutes and it spits out all the files that were touched for that 1 minute period and lists what qtrees/volumes they are in?? On the NOW site there is a file called netapp-top.pl that lists top nfs clients.. this i guess would be the next step up from that and it would list the nfs client and a list of files it accessed ?? is this doable?? is there any scripts ?? anything like solaris lsof for the filer?? -- Greg Wilson System Administrator gwilson(a)connect.com.au

Data corruption and TCP checksums
by Edward Hibbert (eh＠dataconnection.com) 22 Oct '03

22 Oct '03

We've just tracked down an evil problem where corrupt data is being returned on NFS reads from a NetApp. This turned out to be because of dodgy network cables introducing packet corruption - word-aligned values of 0x0000 and 0xFFFF apparently produce the same TCP checksum result, so any corruption which interchanges those values get through to the application. Our application has a file which is a bitmap, and contains a lot of this kind of data - so it's just the sort of file you'd expect this problem to occur on. Obviously now that we know about this there's stuff to do - monitor CRC errors more carefully, perhaps change the structure of our data. But I was wondering whether anyone else has experienced similar problems and come up with any imaginative solutions to it?
