FW Generic Failure
by Michail Michalakis 22 Nov '07

22 Nov '07

Mon Nov 19 12:56:46 EET [esh.bypass.host.port:CRITICAL]: replayed event: [IN] port on channels 0b/UNUSED shelf id 2 ESH B Bypassed due to FW generic fault Does any understand the above message is was found on a FAS270, an the aggregate on this volumes status is online, raid-dp, redirect. I suspect that it is the FAS270 controller and not the ESH Module, because when changing the modules the error remains. All LED on front and back are green.

sdcli error
by Raj Patel 20 Nov '07

20 Nov '07

Hi all, When I run the following command - C:\Program Files\NetApp\SnapDrive\sdcli.exe snap mount -r mosssqlp1 -k F -s sqlsnap__mosssqlp1__recent -d Q I get the following error - Initializing...Unable to connect to the virtual disk in snapshot. Error : Not enough storage is available to complete this operation. Which is quite different from - Error description: No space left on device. Which is what I get on a full volume - so its completely understandable. The 'Error : Not enough storage is available to complete this operation' would appear to be a red-herring (ie nothing to do with storage or the SAN per se but some oddball way of Windows 2003 telling me theres some other problem. The annoying error seems to indicate a possible rpc problem in Windows rather than with SnapDrive itself. The same script on the same machine will happily mount snaps from other machines for backup purposes and I can't really pinpoint why its not mounting these snaps. If it does turn out to be an rpc issue could it be that the domain account on the server under which SnapDrive runs cannot be validated on this box ? I still haven't got my head around how sdcli talks to the SAN - if I have a backup server mounting snapshots of luns being used on other systems does it need to be able to talk to the system using the luns - why can't it deal direct with the SAN ? Thanks in advance for any tips or toubleshooting suggestions. Cheers, Raj.

Re: Are disks in FAS2050 expansion shelves software assigned?
by Ramesh, Deepa 16 Nov '07

16 Nov '07

Yes, the FAS2050 uses software based disk assignment. Any additional disks/shelves added to the system will need to be assigned. Details on disk assignment can be found in the Storage Management Guide. Thanks, Deepa -----Original Message----- > From: Stephen C.

Thought I'd share
by Glenn Dekhayser 15 Nov '07

15 Nov '07

Had an interesting issue over the weekend at a client, with a happy ending thanks to Netapp support. Client had two aggregates on a 980 controller, one with 144GB drives, one with 300gb drives - each aggr had 1 hot spare, running raid-dp. During the weekend raid scrub, one of the 144gb drives starts popping errors and goes into a predictive failure mode, so the diskcopy starts copying data to the hot 144gb spare. Halfway through this, the predictively bad drive actually fails hard- now it gets interesting. Rather than rebuild the rest of the 144gb hot spare from parity (since it already had much of the data), ontap decided it would abort this diskcopy and pick ANOTHER spare drive to rebuild to- of course the only one left was a 300GB drive, so it picked that one- and instead of right-sizing it down to 144gb, it let it stay at the original size (since you can do that, as Adam Fox reminded us in an earlier post today). So now we had a 144GB aggregate with a single 300GB disk in it, and also, I have no 300GB spares left! Not good. So 1st level support zeroed out the 144gb drive that had the aborted diskcopy on it, and attempted to fail the 300gb drive with a disk fail -f, in order to bring balance back to this world. Didn't work; turns out if there are no spares, you can't do a disk fail on the command line, not even with -f! So the next answer here was to move all the data on the 144GB aggr to another aggr, wipe out the original aggr and rebuild. But of course we didn't have enough space to do that anywhere, so I was going to have to borrow a 300gb shelf from my friendly netapp office to do the trick, and I could see my weekend slowly slipping away. Luckily it didn't come to that; we escalated it up to support. The final answer involved literally yanking the drive, and some other stuff with the disk fail -i command. This started building back to the original 144gb hot spare, and that took care of the issue. The moral of the story - if you end up accidentally recovering to a bigger spare than the rest of your disks in the aggregate, don't despair! Netapp support can help. Also- it's probably a good idea, in mission-critical environments, to have at least TWO hot spares of each size. Glenn (the other one)

Same aggregate, different size disks?
by Wes Hardin 15 Nov '07

15 Nov '07

Is it possible to have both 144G and 300G disks in the same aggregate, but different raid groups? I can't seem to find any documentation on this. I tried using the ONTAP Simulator to test this, but the simulator seems to have a bug because I was able to add disks of multiple differing sizes to the same raid group (without right sizing them to a common size) and I was even able to add a smaller disk to a raid group of larger disks. -- Wes Hardin

Aggregate Redirect

I have an IBM NS3700/FAS270, my problem is that aggr0 and all volume within status is redirect. Aggr1 does not have this problem. developerserverdb online raid_dp, flex nosnap=on, nosnapdir=off, snapmirrored minra=off, no_atime_update=off, read-only nvfail=off, redirect ignore_inconsistent=off, snapmirrored=on, create_ucode=on, ===== SYSCONFIG-R ===== Aggregate aggr0 (online, raid_dp, redirect) (block checksums) Plex /aggr0/plex0 (online, normal, active) RAID group /aggr0/plex0/rg0 (normal) Aggr State Status Options aggr0 online raid_dp, aggr raidsize=14 redirect aggr1 online raid_dp, aggr root, raidsize=14 NO reallocation or wafl process is running.

Upgrade firmware, ONTAP and add hardware in one step?
by Stephen C. Losen 14 Nov '07

14 Nov '07

We are adding FC interface cards and new shelves of 750G disks to a FAS960c pair. We need to upgrade ONTAP from 7.1.1.1 to 7.2.3 to support the disks and our system firmware is not the latest. I was wondering if we dare try and do all of this with a single reboot like this: install firmware files and download install ONTAP files and download halt and run update_flash to install firmware power off install interface cards connect new shelves and power them up power up the heads I am concerned that now the filers will come up with new firmware, a new version of ONTAP, and newly installed hardware and disks. Am I asking for trouble? My conservative nature tells me to install the firmware, boot back up, install ONTAP, reboot, shut down, power off, install the new hardware and power back on. It will take only a few more minutes. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

nfs tunneling with SSH
by Willeke, Jochen 14 Nov '07

14 Nov '07

Hi toasters, as we are getting more and more secure we do now have some firewalls within our internal network which prevent us from accessing e.g. installation files or some tool-stuff from central stores on our filers. I have tested a little bit with ssh-tunneling for NFS. With my client this works well, but i have trouble doing this with my filers. Here is what i do: client>> ssh -f -L 7777:filer:2049 -l root nstore2 sysstat 100 client>> ssh -f -L 8888:filer:4046 -l root nstore2 sysstat 100 Where 2049 is the filers nfs port and 4046 ist mountd. On the filer i have exported a volume /vol/test to the filer itself. When i now run client>> mount -t nfs -o tcp,port=7777,mountport=8888 localhost:/vol/test /mnt The client hangs and on the filer i see the message: [openssh.dispatch.protocol:warning]: SSH dispatch failed from address myclientsIP, type 90, packet 10 Has anybody ever tried this or has an idea where my problem is?? Or does anybody know if this is absolutely impossible with filers? Best Regards and thanks in advance Jochen
