NDMPCOPY question
by David McWilliams 27 Apr '10

27 Apr '10

One of our files has a space in the qtree name and I'm struggling to execute an NDMPCOPY command on it. I have tried put double quotes & single quotes around the qtree name and the full path and a backslash in front of the space, but no difference, see below for an example; ndmpcopy -sa root:oldsys mis-netapp1:"/vol/vol1/education practice" "/vol/vol1/education practice" Ndmpcopy: Starting copy [ 17 ] ... Ndmpcopy: mis-netapp1: Notify: Connection established Ndmpcopy: fas3050: Notify: Connection established Ndmpcopy: mis-netapp1: Connect: Authentication successful Ndmpcopy: fas3050: Connect: Authentication successful Ndmpcopy: Failed to start dump on source Ndmpcopy: Done Sláinte, David "Build a man a fire he'll be warm for a day, set a man on fire and he'll be warm for the rest of his life" - Terry Pratchett Checkout my photos - http://www.panoramio.com/user/1113507

Some questioning about FlexClone
by Simon Vallet 23 Apr '10

23 Apr '10

Hi, we're currently considering the purchase of a FlexClone license for some of our database environment (MySQL 5, DOT 7.3.2, ~2TB data, growing fast), but I've been wondering if it provides the functionality we need. AFAICT, what we'll get with FlexClone is a read-write snapshot -- which is fine --, but the real question is about service migration between two copies : let's suppose we have a dev and a production database ; how would we migrate the service (e.g. a MySQL server) between the two? I realise hot migration will be complicated to implement, but do some of you already have played with this kind of things before?

routing issue with 2 vifs on same subnet?
by Romeo Theriault 22 Apr '10

22 Apr '10

We recently upgraded our SAN ethernet switches and moved from a config where we had one vif with all the nic ports on one switch to a config where we've split the nic ports out across the switches. So we now have two vifs split across the switches. Both vifs are on the same subnet and they have separate ip addresses as our switches don't support cross-switch etherchannelling. We currently have everything going through vif1 and this is working just fine. The issue is starting when I start trying to access the second vif, vif2. I can ping vif2 fine, ssh into vif2 fine but when I try to nfs mount an export on vif2 it hangs, waiting, waiting... then mounts it after about 30 seconds (on linux, solaris hosts don't seem to every mount it). But this only happens from some hosts. Other hosts can mount their exports on vif2 just fine. I took a tcpdump of the process and what appears is happening is vif1 is responding to requests to vif2, for a while, and then eventually responds out of vif2 and the linux servers is then able to mount the export. I've tried disabling fastpath and this didn't help. I then started thinking that I possibly need to have the vifs on seperate subnets but netapp support has verified that it should work fine on the same subnet. I'm not getting anywhere fast with netapp support so thought I'd see if anyone else has any ideas. Thanks, -- Romeo Theriault

FC port fan-in
by Fred Grieco 20 Apr '10

20 Apr '10

Toasters, I am looking at the specs for the Netapp 3140 cluster, and attempting to find the answers to two questions: 1) How many VMWare hosts can I have looking at the same set of LUNs? Before I have real-world performance issues? 2) How many multipathed hosts can I have, total, pointed at a four-fc-port cluster? The limit in #1, according to NOW, is 256 (256 initiators per igroup). What are your experiences in with this in large VMWare farms? #2 seems to be 256 according to NOW, but there is a limit called "FC port fan-in" of 64. This would seem to limit the total number of HBA initiators pointing at a port to 64, which, since all my HBAs see all my ports, would limit the total hosts to ... 64? What does this number mean effectively for hosts with two cards? TIA, Fred

NIC's
by Carl Howell 15 Apr '10

15 Apr '10

If NIC's like the X1037's and X1047's are OEM'd from some company like Intel, can I just go out and buy the Intel version and it will work? I've got some older filers I need to move off of fibre onto copper and was hoping I could just purchase the manufacturer's version and save some money. Thanks, Carl Howell Systems Engineer Information Technology Services University of West Florida

df -s value

Maybe I am missing something here: FAS6040 DOT 7.3.1.1 FC 500GB LUN 0 fractional reserve thin provisioned running dedupe (love it) I think there is a bug maybe in my version of DOT. I ran df-s on a volume, and this is what I am seeing. /vol/netapp_vol_vmware_DMZ_01/ 79484444 74719212 48% Should it be around 94% ?

Odd message on one VIF
by Page, Jeremy 14 Apr '10

14 Apr '10

I ran into an odd problem this week where CIFS would not let me delete a share and would not terminate. Eventually it got to the point where I just failed over to resolve the issue (which worked) but when the 2nd controller came back up I saw this in the logs: Tue Apr 13 23:53:26 EDT [gvr-pvif.setMediaFail: vif: unable to set media type on link e2a for tgif (error 22) Tue Apr 13 23:53:26 EDT [gvr-pvif.setMediaFail: vif: unable to set media type on link e2a for tgif (error 22) Tue Apr 13 23:53:26 EDT [gvr-pvif.setMediaFail: vif: unable to set media type on link e2b for tgif (error 22) Tue Apr 13 23:53:26 EDT [gvr-net.ifconfig.mediatype: The mediatype specified for tgif in the /etc/rc file is not valid for this interface and will be ignored. Tue Apr 13 23:53:28 EDT [gvr-netif.linkUp: Ethernet e2a: Link up. Tue Apr 13 23:53:28 EDT [gvr-netif.linkUp: Ethernet e2b: Link up.

sdf and GX/OT8CM
by Kennedy, Jeffrey 14 Apr '10

14 Apr '10

Anyone who is running GX or 8CM, what are you doing to handle the sdf v. df issue of nested mounts? For those who don't know sdf is 'spinnaker' df and is used to find out df info on a nested volume in the GX namespace. I assume it's similar in 8CM as well but have not yet seen it. In any case, my first thought was simply a wrapper to determine if the mount was on a gx system and then either call sdf if so or pass off to the OS df if not. But if there's a more elegant solution I'd like to know. Thanks.

What exactly does SnapDrive buy me?
by Page, Jeremy 10 Apr '10

10 Apr '10

It looks like we're getting funding for our DR project. The bare bones are using snapmirror to replicate an Oracle DB offsite alone with a few dozen front end/infrastructure VMs. Two of the items we've been quoted by our vendor are SnapDrive & SnapRestore. I can understand snaprestore but why would I need snapdrive at the DR site? I don't even use it at our primary site, the Oracle system is very static, we do not have the hardware capacity to run a cloned instance and I'm comfortable with scripting a snapshot. I tried reading NetApp's SnapDrive document <http://media.netapp.com/documents/snapdrive.pdf> and it looks like it will do every buzzword under the sun but I have no idea what it really gets me other than the ability to see/control snapshots from the server - which I don't want. In addition it breaks the KISS idea which is important, especially since this system will be in another geographical location and not have as many eyes on it as a live system would. Am I missing something? Please be advised that this email may contain confidential information.
