Re-cable existing shelf into new loop
by TAYLOR DANIEL 29 Nov '17

29 Nov '17

Hello, We need to re-cable a shelf out of its current loop into a new one, just interested to know if anyone had done this without issue? We want to do this non disruptively so keen to hear other peoples comments and thoughts on this and if possible without causing a panic. Running 9.1P8. Thanks Dan

3.5" 15KRPM -vs- 2.5" 10KRPM SAS
by John Adams 27 Nov '17

27 Nov '17

Hello, I have AGGRs made out of 3.5" 15KRPM SAS drives. One of these drives failed, and NetApp sent a 2.5" 10KRPM SAS drive in a 3.5 sled as replacement. After asking about this, they said: After investigating, the following were my findings: "As part of the NetApp qualification process, there is no performance degradation with the qualified X90-412B-R6 / SP-412B-R6 10K RPM drive as the seek distances are reduced to be equal to a full stroke 15K RPM drive." As for the physical size difference: "The only difference is that the 412A is a 3.5 inch HDD while the 412B is a 2.5 inch HDD. The difference in size is negated by a bracket within the carrier assembly in the 412B. So while the two HDD’s look different, the 412B is fully compatible with the 412A." So what's your take on this? The "don't mix 10K and 15K drives in the same aggr" keeps ringing away in my head. Thanks for your thoughts.

I think it’s time for a lab experiment with hybrid aggregates of different speeds. Maybe there’s a way to mix in some 7.2k drives for fun. .

But really, mixing is a BEST practice not-to-do, but when you explore the practicability of doing so, it's not so bad, and the differences exist only on paper* when you do whats said here, 2.5" in a 3.5" aggr. Its a lot of fun math, but sector density per RPM...etc...10k is the "same" as 15k. Smaller disk, shorter seeks (butterfly worst case)....there's really no argument that supports that this is a bad idea anymore. Because the best-practice back when, was when everything was equal. It no longer is..so it doesnt matter in the context of the old maths anymore.

cluster mode quota management?
by Sami Kapanen 22 Nov '17

22 Nov '17

Hi, What tools do you use for user quota management with clustered ontap? With 7mode we used the System Manager GUI, but now cmode 9.0P1 there is bug that won't list all users in GUI.. and that has been open for a long time now, apparently our case is the only one :/ Sk

FAS2240-2
by Sally Rogers 16 Nov '17

16 Nov '17

I have an FAS2240-2 that is out of maintenance. I'd like to buy some shelves off eBay and add them to it but I'm not sure if the number of shelves/disks is limited by the license codes. Does anybody know if there is any such restriction besides the 144 disk limitation? Thanks, Sal

NDMP to tape, cDOT 8.3, command line?
by John Stoffel 09 Nov '17

09 Nov '17

Guys, I need to write one damn volume to tape on a cDOT 8.3.2p9 four node cluster. LTO5 drives hooked up with FC. I can setup NDMP in VServer mode and get that part working. But I can't find the tool to start a dump to tape of the volume. ndmpcopy just does filer to filer copies. You can't use 'dump' any more from the console, it's all NDMP based now. I guess I'll have to just configure Netbackup 7.7.3 with NDMP to make this happen, but then I'll need to figure out how to backup a specific snapshot. Such a pain... John

Ontap 8.2.5 FAS8020 SP firmware 3.0.4
by Douglas Siggins 08 Nov '17

08 Nov '17

Greetings, Has anybody upgraded to Ontap 7mode 8.2.5 on FAS8020? I do have a case in, but as you can imagine it is moving slowly. I dont yet feel the need to start screaming. The Ontap update is autoupdating the SP to 3.0.4, and causing some issues: sp.device.fw.mismatch:warning]: Device firmware version mismatch detected: eth_switch:Rev:2,Img:3-mismatch Couple of oddities with this: There isn't a 3.0.4 SP firmware available via netapp website nor is it documented in the SP matrix https://mysupport.netapp.com/NOW/cgi-bin/fw?platform=FAS8020&type=sp_ontap&… https://mysupport.netapp.com/NOW/download/tools/serviceimage/support/Servic… I've gone into debug mode and issued SP netapp01*> sp switch-update Which seems to have worked, but the new error then becomes: sp.device.fw.mismatch:warning]: Device firmware version mismatch detected: 12:Rev:fan,Img:-mismatch So I presume I should run: SP netapp01*> system fan update Warning: system sensors monitor and system sensors thermal-mgmt should be disabled both on this controller and partner controller (if installed). Continue? [y/n] At which point I thought it best to figure out exactly what is going on here. I think the following message might be related. monitor.temp.unreadable:info]: The controller temperature (CPU0 Temp Margin) is not readable. Regards, Douglas

RE: Windows-to-unix usermapping through LDAP not working: RESULT_ERROR_SECD_CONFIGURATION_NOT_FOUND

Thanks Filip. I’d suggest opening a case and getting a bug filed. From: Filip Sneppe [mailto:filip.sneppe@gmail.com] Sent: Friday, October 6, 2017 2:02 AM To: Parisi, Justin <Justin.Parisi(a)netapp.com> Cc: toasters(a)teaparty.net Subject: Re: Windows-to-unix usermapping through LDAP not working: RESULT_ERROR_SECD_CONFIGURATION_NOT_FOUND Hi Justin, Thanks for taking the time for replying to this. To answer your question, I specified the SVM. But based on your comment that it should work to use the built-in schemas, I did a little more testing, and I think the problem is related to the MS-AD-BIS schema that was added in 9.1. In my experience, it cannot be used directly. Below is an example with: - direct use of the MS-AD-BIS schema (doesn't work) - use of an unmodified copy of the MS-AD-BIS schema (works) - direct use of another built-in schema, AD-IDMU (also works) (in the output below, I search-replaced the clustername, the domainname, and the username) This is on 9.1P8. cluster::*> ldap delete -vserver nfscorpprd01 Warning: "LDAP" is present as one of the sources in one or more ns-switch databases but no valid LDAP configuration was found for Vserver "nfscorpprd01".

ssh <vserver> vol show <volume_full_name> hangs
by John Stoffel 27 Oct '17

27 Oct '17

Guys, I've run into an interesting problem on a 4 node cDOT cluster running 8.3.2P9 today. Basically, I've setup a user account with access to a particular VServer. It's used for creating snapshots and such. When we do the command: ssh <vserver> vol show <volume_full_name> it just hangs, and doesn't show anything. We have to do a Ctrl-C to get it back. But if I simply do a simple: 'ssh <vserver> vol show' it all works nice and quickly. So wierd. I can even do the show command when there are multiple volumes using a wild card and it works. ssh <vserver> vol show '<volume_*>' works, as long as it matches MORE than just the single volume. Using the -instance flag doesn't help either. I even tried moving the admin lif to another node, thinking that one node had some stuff ssh processes, but it didn't make a differnce. Thanks, John
