RE: Quick question about "LUN protocol type"
by David L. Lambert 19 Dec '08

19 Dec '08

OK, I guess I phrased my question poorly. I want to make a LUN that will only be accessed by a Linux host. It will have a partition-table, and one partition in that partition-table. That partition will have a labeled ext3fs filesystem on it (Ubuntu's "mount LABEL=..." seems more reliable if I do it that way). Should I tell the NetApp that it's a "Windows" or a "Linux" LUN? Or will the NetApp behave exactly the same either way? -- David Lee Lambert -----Original Message----- From: Jeff Mohler [mailto:speedtoys.racing@gmail.com] Subject: Re: Quick question about "LUN protocol type" Why not map two Luns? ___ Sent from my $400 phone that has no text editing tools.

Serial console cable shenanigans (FAS3020s to Cyclades)
by Nick Silkey 16 Dec '08

16 Dec '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 toasters -- I am trying to troubleshoot connectivity issues between my serial consoles and my 3020s. Per NetApp, we are 'required' to hang the X881[1] rj45-to-db9 dongle off the filers. But my Cyclades can easily grok rj-45. A phone call to NetApp revealed that a pin-out of: 4 -> 4 3 -> 6 6 -> 3 should allow me to not have to used the NetApp dongle (TSE appears to have walked the pin-outs backwards to come up with the above). Havent tested this yet; looking to confirm from those on the list since the pinout is non-standard. So is anyone out there tapping into their Cyclades without the NetApp db9 dongle hanging off their 3xx0 filer? Insight appreciated. Thanks.

Leopard globalSAN iSCSI and 7.1.3
by Carl Howell 15 Dec '08

15 Dec '08

On one of our Xserve¹s, I¹ve used the Studio Network Solution¹s iSCSI initiator(3.3.0.43) with OnTap version 7.0.5 and didn¹t have any problems. Now, after upgrading to OnTap version 7.1.3, I get the following error: Mon Dec 15 16:18:36 CST [iscsi.protocol.violation:warning]: ISCSI: iSCSI protocol violation, 'Initiator did not respond to offered MaxBurstLength' Does anyone have any ideas on how to fix this? Thanks, --Carl

Re: Quick question about "LUN protocol type"

No, when I say a "DOS partition table" I mean what I get by running the program "/sbin/fdisk" under Linux, and subsequently doing e.g. mke2fs -L APPDATA -j /dev/sde1 instead of just doing mke2fs -L APPDAT -j /dev/sde On Monday 15 December 2008 11:19:48 am Webster, Stetson wrote: > Question: Is DOS directly interfacing with the lun?

Quick question about "LUN protocol type"
by David Lee Lambert 15 Dec '08

15 Dec '08

In the FilerView LUN wizard, I see the following options for "LUN protocol type": Solaris Windows - "The LUN will be used to store a raw disk device in a single-partition Windows disk" HP-UX AIX Linux - "The LUN will be used to store a Linux raw disk with no partition table" NetWare VMware The "na_snap" manpage also lists the types "windows_gpt" and "vld". If we're making a LUN with a DOS partition table and one partiton that will be used by a Linux host, should we use the "Windows" or "Linux" setting? Or does it matter? -- David L. Lambert Yahoo!

RE: qtree "top" tool
by Glenn Walker 14 Dec '08

14 Dec '08

All good points. That said, when I said 'write tool' and 'cifs top' I was thinking more interactive on the CLI of the actual filer to spot check stuff. I could have all of the talent in the world and not be able to produce this without getting it checked into the ONTAP code ;) Perhaps I will un-lazy myself when I get free time and give a client script version of this a whirl.

do toaster need a day off? (WAFL scans)
by Todd C. Merrill 13 Dec '08

13 Dec '08

Two scenarios: 1. R200, 7.2.2, two 12 TB aggregates, 85 volumes of various sizes, 70-80% full snapvault secondary, ALWAYS receiving snapvaults and nearly ALWAYS spinning to tape. 2. 6070, 7.2.4, two 8 TB aggregates, 27 volumes between 150 and 700 GB, 60-70% full recent migration (via volume snapmirrors) from 980's, serves home directories to NFS and CIFS clients. We stopped all snapmirrors/snapvaults to the R200, terminated CIFS, and shut off NFS. CPU utilization remained 90%+ and disk reads remained high for the next 6-7-8 hours until it finally quieted down. After volume snapmirroring the home dirs from the 980's to the 6070, we re-pointed the snapvaults (modify; start -r) and allowed NFS and CIFS access. 5 days later, file server performance still blows (worse than the 980's -- D'oh! Egg, meet Face; Face, meet Egg), with moderate CPU load 30-40-50% but high disk reads. In both cases, we determined that lots of WAFL scans were going on: container block reclamation volume deswizzling active bitmap rearrangement (of course...this NEVER seems to stop) and a few other types that have already scrolled out of my buffer. So, we figure--eventually--the WAFL scans will catch up and performance will go back to normal on the 6070. The performance of the R200 always blows. So...here finally is the question: do toasters need a day off? Said another way, to maintain acceptable performance and low/fast response times, do toasters need a goodly amount of (relatively) idle time in order for these WAFL scans to complete? Could the sub-optimal performance of another group of six 6070's that we have, that we *pound on* 7x24, be explained in part by always having at least the container block reclamation scan going on?

Snapvaults schedules not at the top of the hour
by Page, Jeremy 10 Dec '08

10 Dec '08

What would be the best way to get snapvault to move a snapshot from the primary that's not created on an hour boundary? We're putting our DB into hot backup mode at 9:05 and I don't want to make the DBA change his scripts if possible, is there a way (maybe with rsh+cron) that I can manually create a snapshot at 9:15 and then use snapvault to transfer it?

7.3x on 800's
by Carl Howell 09 Dec '08

09 Dec '08

Has anyone attempted to put OnTap 7.3 on an 800 series filer? Can you do it? Is it simply that NetApp doesn¹t support it, or will it not run at all? Thanks, --Carl
