Disk inventory out of sync.
by Jeff Cleverley 15 Jun '12

15 Jun '12

Greetings, We have a 3140 cluster running 7.3.5.1P4 at one of our sites. There were 2 drive failures (not the same raid group), hot spares kicked in, and the hard drives replaced. Everything seems fine to here. The problem comes in because the partner is showing a disk mismatch. It sees all the drives, but the owner of the replacement drives doesn't in some cases. If I do a "disk show" or an "aggr status -r" on the disk owner, it sees the disks. Any of the "storage show disk <option>" commands on the owner do not show the replacement drives. Will a cluster takeover/giveback wake up the filer or are there any other tricks to get everything on the disk owner to show the drives? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

Firmware Automation
by Thomas, Timothy B 13 Jun '12

13 Jun '12

NetApp states this is "unsupported", so I'm posting this here for ideas. For the last 10 years or so we have used a process to automatically download and push disk and shelf firmware to the filers. The process begins with a wget to grab the all.tar file: wget --http-user=userid --http-passwd=password -P /path/to/put/it http://download.netapp.com/download/tools/diskfw/bin/all.gz Now with the recent changes on the support site this year, that method no longer works. I tracked down the new location and tried this: wget --http-user=userid --http-passwd=password -P /path/to/put/it http://support.netapp.com/NOW/download/tools/diskfw/bin/all.gz but it fails, even with a few other flags I tried, the best I could get was a login.html file downloaded. So it's clear that Netapp is redirecting the request for authentication. I looked into wget a further and tried to login, grab the cookies, save them to a file and then use that authentication to grab the file, no luck there either. wget --no-check-certificate --keep-session-cookies --save-cookies cookies.txt --post-data 'user=userid&password=password&postpreservationdata=""' https://login.netapp.com/oamforms/login.html wget --no-check-certificate --load-cookies cookies.txt -P /path/to/put/it http://support.netapp.com/NOW/download/tools/diskfw/bin/all.gz So that's my dilemma. I'm looking for ideas, work arounds, other implementations, anything so I can automate the download of the all.gz and the all_shelf_fw.tar files. >From there my process will continue as before. Thanks in advance! Tim

Host based Lun snapshots (snapdrive) with OnCommand or Protection Manager
by Greg S Wilson 07 Jun '12

07 Jun '12

Anyone worked out how to do Host based lun snapshots (using snapdrive) with OnCommand or Protection Manager and policies ? It seems utterly amazing you have to write a batch file and call sdcli and then setup a scheduled tasks to take snapshots with snapdrive. We have a lot of luns mapped to hosts and its going to get very messy with all these batch files running.

AutoSupport cannot connect to url https://support.netapp.com/
by Fletcher Cocquyt 05 Jun '12

05 Jun '12

One of the nodes in this cluster is not able to connect to netapp to post its ASUP since we updated to 8.1 GA 40 days ago: AutoSupport (HA Group Notification from na04 (USER_TRIGGERED (COMPLETE:completedShelfFWupdate)) INFO) cannot connect to url https://support.netapp.com/put/AsupPut/ [na04:asup.post.retry:info]: AutoSupport message (HA Group Notification from na04 (PERFORMANCE DATA) INFO) was not posted to NetApp for host (0). The system will retry later to post the message User triggered also fails to post to netapp.support.com (although we receive the emails internally): Jun 4 10:20:03 [na04:asup.post.host:info]: AutoSupport (HA Group Notification from na04 (USER_TRIGGERED (testing)) INFO) cannot connect to url https://support.netapp.com/put/AsupPut I compared options auto output on both nodes and they are the same DNS settings are the same - and functional na04*> ping www.netapp.com a878.b.akamai.net is alive Any other areas to check? thanks

Getting NFS3ERR_ACCES for NFS Share
by Ray Van Dolson 30 May '12

30 May '12

IBM N6240 running ONTAP 8.0.2P3. Have a number of NFS shares set up with pretty straightforward permissions: /vol/napc2_p2_Data6 -sec=sys,rw,nosuid Filer is connected both to NIS and AD and most shares are shared out via both NFS and CIFS. When attempting to copy file content to the share above (all shares really, but using this one as an example), I get a Permission denied error (packet capture shows this to be an NFS3ERR_ACCES message). The file itself is successfully created, but is size zero. Once the file is created (with error message) I can then run the exact same copy command again and this time the data is populated. Packet capture seems to show the CREATE call succeeding, while the subsequent SETATTR call failing with the aforementioned error. Anyone run into something like this before? NFS client(s) in this case are Linux (RHEL, Fedora). NFSv3 is in use with NFSv4 explicitly disabled. Ray

Install OnCommand Core on Ubuntu?
by Fredrik Pettai 30 May '12

30 May '12

Hi, Earlier I got a tip on how to install and run DFM on an Ubuntu server instead of RedHat / SuSE (http://www.eigenmagic.com/2009/06/26/how-to-install-netapp-dfm-on-ubuntu/) However, I would like to do the same thing with OnCommand Core, but the former DFM routine doesn't seem to work well at all. So, I wonder if someone else has manage to do the same thing with OnCommand Core and succeeded? Thanks, /P

Snapvault stop on 8.1 7-mode
by Jeff Cleverley 30 May '12

30 May '12

Greetings, I posted a couple of weeks ago about snapvault relationships not going away. It turned out the snapvault stop had not cleaned up all the associated snapshots on the destination used for qtrees. Since that time I have had a similar problem on multiple filers. The problem seems to be that snapvault stop doesn't actually do anything in 8.1. I upgraded one of the filers from 8.0.1P1 to 8.1 GA. I was able to get the SV stop to work at 8.0.1, but it hasn't worked once since I've upgraded. One of my other filers is doing the same thing. Ultimately after multiple SV stop attempts (at least 5), rebooting the filer, then doing more multiple SV stops, I was able to get some of them to lose the SV lock. I've got a call open for this but haven't received any useful information from it. This is an example of the error message I get. isolation> snap delete former_mofab isolation(0118075592)_former_mofab_root-dst.0 Snapshot isolation(0118075592)_former_mofab_root-dst.0 is busy because of LUN clone, snapmirror, sync mirror, volume clone, snap restore, dump, CIFS share, volume copy, ndmp, WORM volume, SIS Clone The snapvault stop was the first thing run. Nothing else was done until after it completed. Everything else is cleaned up. The schedules, relationships, etc. A snapvault status doesn't show a source because that has already been cleaned up. The volumes are not part of a mirror and this snapshot is the only special snapshot in the volume. I've also taken the volume offline and brought it back online but that doesn't help either. Is there some magic recipe at 8.1 to make SV stop work? I can't keep rebooting filers and spending 30 minutes per volume doing multiple stops and snap delete attempts.

VSC Privilege
by Carl Howell 30 May '12

30 May '12

I'm trying to get the Virtual Storage Console working using a domain account. Every time I try to log in, it gives me "In order to determine which controller privileges are allowed for this username, the following controller privilege is required: useradmin-user-list" The domain user account I'm using is a member of a group on the filers that has a role with login-*, api-*, and cli-* capabilities. What am I missing? Thanks, Carl

Curiosity killed the NetApp admin: Empty lun not empty
by Peta Thames 30 May '12

30 May '12

Hi all, I have a question born mostly out of curiosity but also slight paranoia. I don't know VMware very well so forgive me if I'm missing something obvious. I have a VMware lun that is thin-provisioned and presented via FC. vSphere reports that the lun has no VMs in it, and yesterday I deleted the datastore from VMware. It was only mapped to one cluster. The lun is currently offline and no-one's complained (yet). On the filer, it reports that the lun occupies 962.9gb of its 1tb. Surely it should be empty? There are no snapshots. We don't use snapmirror. Fractional reserve was set to 100 but I've since set it to 0 and it made no difference. I haven't been here long so I don't know any more history I'm afraid. Any ideas? Thanks, Peta P.S. If anyone was curious about my last email sent to this list re reallocation and de-duped volumes, I can't get a detailed answer from NetApp support aside from "generally, don't reallocate de-duped volumes". So that's what I'm doing (or not, so to speak).

Poor NFS 10GbE performance on NetApp 6080s
by Dan Burkland 29 May '12

29 May '12

Hi all, My company just bought some Intel x520 10GbE cards which I recently installed into our Oracle EBS database servers (IBM 3850 X5s running RHEL 5.8). As the "linux guy" I have been tasked with getting these servers to communicate with our NetApp 6080s via NFS over the new 10GbE links. I have got everything working however ever after tuning the RHEL kernel I am only getting 160MB/s writes using the "dd if=/dev/zero of=/mnt/testfile bs=1024 count=5242880" command. For you folks that run 10GbE to your toasters, what write speeds are you seeing from your 10GbE connected servers? Did you have to do any tuning in order to get the best results possible? If so what did you change? Thanks! Dan
