Netapp Instructor Position Open
by Nick Bernstein 27 Dec '10

27 Dec '10

Hi all, I just wanted to let you know that there is an open position for a Netapp Instructor. You should have extensive real-world netapp experience, be personable, funny, able to tell stories and explain complex subjects in a simple manner. People who have worked as PSEs are probably a good fit. The salary is very competitive, but the main benefits are in the flexibility and schedule. You'll get to travel (I've been to places like hong kong on the company dime) and meet lots of people. I generally only work about two weeks / month, but some some instructors work every week. We will happily teach you how to teach, but just to be up-front, the process of becoming an instructor isn't instant. You'll have to take each of the course three times (one to audit, one to co-teach, and one supervised-solo), and you'll have to do this for the fundamentals class, the san, nfs, cifs, data protection and boot camp classes - it can take a while. Once you're through that however, I can personally attest to the fact that it's an *amazing* job. You would be reporting to me, and I'm a pretty darn good boss. :) Well, I am if you like my management style, anyway. Basically all I want is regular reports on how things are going, what help (if any) you need to do your job better, and then I leave you the heck alone. One of the main benefits of this job is you are your own boss, effectively sub-contracting, and we just make sure you've got everything you need, make sure your reviews are consistently good, and you're getting exposed to the new stuff coming down the pipe. There will also be great opportunities to get exposed to all sorts of other technologies too - cisco, vmware, ubuntu linux - it's really fun to be able to audit a whole range of different courses, and then bring that back to your netapp classes. If you're interested, please email me your resume, or a link to it - any standard format is fine. For bonus points, pretend you're talking to an eight year old, and explain why the sky is blue. Feel free to look it up, but the actual answer should be yours. Kindest Regards, Nick Bernstein, Director of Netapp training, ICM PS: If this is an inappropriate use of the list, please accept my apologies in advance - I've been on this list for a number of years and have always been impressed by the members; I wanted to give list-members first shot at the position.

Virtual storage console RCU mistery...
by Milazzo Giacomo 23 Dec '10

23 Dec '10

Hi all, for the first time I've experimented the RCU tool that now is inside the VSC 2.0.1 for VMware. But during the tests I've noted something that left me doubtful. I've always thought (and this is the NetApp message to folk :)) that the "rapid" clone utility used some way the flex_clone or the lun_clone techniques to quickly create vmdk images starting from something on active file system volumes... I mean: vmdk on a lun/volume -> Data Ontap snapshot of this -> flex_clone -> rewritable image of the originating data and, of course, all this for dozens of VM performed very quick because there's nothing to transfer!!! Instead when I ran those test I've choosen a running VM, selected the NetApp menu item -> provisioning and cloning -> rapid clone and, looking both at the putty on my filer and on the status bar of vCenter I've seen no activities on the NetApp at all (no snapshots, no clone and so on...) while the vCenter reported: creating snapshot (a VMware one!!!) -> copying ....copying??? In short the same time and technique I could script or manually execute. So, why the rapid clone tool asked me for a flex_clone license??? And why if I would use it on FC or iSCSI LUN? I could understand for VMware datastore on NFS...And, last, why a flex_clone if there's NO cloning (data ontap) at all? Have I missed something? Regards,

Snapmanager for everything monitoring
by steve klise 22 Dec '10

22 Dec '10

I have about 10 SQL server running SMSQL and a couple Exchange Clusters running SME. We ran into a bit of an issue where some servers were not running the automated or scheduled tasks, and it went unnoticed for a day or two. The completion or failure job is set via SM email even if successful, so I get a few emails a day to say the least. What I am looking for is what folks use out there to monitor their SMGR jobs/backups. • Do you just rely on email, and if a job does not come in at its specific time, become alarmed? • Do you run a sys logger against the filers and look for those jobs/alerts? • Do you run some fancy script I can bribe you for, and I will buy you a beer in return? • Looks like powershell for Netapp is cool. I ran a snapshot script that was pretty cool.. Maybe ask for some help there. What do you use ? happy holidays! -- View this message in context: http://old.nabble.com/Snapmanager-for-everything-monitoring-tp30502273p3050… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

by Alon Zeltser 22 Dec '10

22 Dec '10

Hello Toasters A-SIS is not supported on fas270 platform ( nearstore personality can't be enable on this platform) I know i can use QSM to mirror a deduped qtree to a fas270 but i wonder what will happen if i will VSM a deduped volume to a fas270 ? will it fail or just occupy more space at the destination If i have a volume which currently not replicating and i enable a-sis on that volume and in the future i want to start mirror this volume with VSM is there anything i can do to reverse the dedupe in order to allow VSM ? Thank you --

Syncmirror (Local) doubts
by Milazzo Giacomo 09 Dec '10

09 Dec '10

Hi all, times ago I used Local Syncmirror to "move" data from old aggregates created with 144 FC disks to new 300 GB FC ones and I remember that the old:new ratio was 2:1, i.e., from an aggregate on 56 144 GB disks on 4 shelves to a new one on 28 300 GB disks on 2 shelves...But I don't remember other stuff related to raid group, geometry of them and so on...simply I used the aggr mirror and Ontap chose the needed disks from a pool of spare (Pool 1 as usual) Now I've a similar issue but with a lot of doubts (re)reading the manual. First of this is that manual states that from original aggregate and the mirrored one disks must be the same number...and I ask myself how I was able to do that job times ago?!? Anyway the problem is this: Current aggregate: 56 disks on 4 shelves of 300 GB but with rg and disk geometry wrong (rg0 20 disks, rg1 26 and rg2 8, a couple of spare). The customer wants to rebuild this aggregate using Local Syncmirror a first time to transfer data to other disks available and a second time to put the data back on the 300 GB disks with a correct rg geometry (only 2 rg with 26 disks each). I've 8 or more shelves with 144 FC disks available. Can I use Local Syncmirror fm the 4 300 GB shelves to an automatic created mirror on those 8/9 shelves letting Ontap choose the disks from the Pool 1 spares? What's about the aggr mirror xxxx -v "victim_aggrname" found on the man sections and not on the manual? Can I create a new aggregate on the 144 GB disks the use in some way this syntax? Once splitted the mirror I will temporarily have the data on the 144 disks (if work the points before) so I will be able to destroy the 'old', zero the disks and then...? To create another mirror to put the data back on the 300 GB disks will I have to create an aggregate before with the right disk geometry I want and then use this as "victim aggregate" It's a little bit complicate I know....I apologize in advance for the headaches I will cause in somebody :) but thank you in advance also! Regards, PS) we're not discussing here questions about raid group size, geometry, performances and other so I please you to avoid to ask or observe thinks like this. Also, options such as snapmirror, backup and restore and so on useless for the moment because we've about 8 TB of data (long time) to move ahed and back and Local Syncmirror offer the fastest way and overall a way usable "hot" with no disruption Dott.

Thanks for update Jeffrey, we've just discovered that there's a but in 3.1 version. We've downgraded to the 3.03 and everything works.

Issue on creating profiles on SnapManager for SAP on AIX
by Milazzo Giacomo 03 Dec '10

03 Dec '10

Hi all, we're experiencing this issue nevertheless we've applied the suggestion stated on "SnapManager for SAP 3.1 Administration Guide" (pag. 45) "SAP uses a standard layout for Oracle database installations. In this layout, SAP places copies of the Oracle control file in the /oracle/SID/origlogA, /oracle/SID/origlogB, and /oracle/SID/sapdata1 file systems. The control file in the sapdata1 file system conflicts with the SnapManager requirements for separating the control files and datafiles into separate volumes and must be adjusted to allow for fast restore capability." Has anyone some suggestion on it? It seems a well known error but we don't find documentation on it. This is the result of the command line issued in verbose mode: root#sapQHR/opt/NetApp/smsap/properties>smsap profile create -profile smsap_profile -repository -dbname smsap -host 192.168.10.88 -port 1521 -login -username smsap -database -dbname QHR -host 192.168.10.38 -osaccount smdba -osgroup dba -verbose < Enter password for profile smsap_profile: ***** [ INFO] SMSAP-20020: Set password for profile "smsap_profile" in user credentials for "root".

The N3600-A20 is a 2050 cluster. EXN4000 is the same as DS14MK4 (the "4" in the EXN4000 name stands for 4 Gbps). You have to find on the shelf two SFP (Gbic) connector plugged on the IN port of the two ESH4 controller.

The N3600 A20 is currently configured as Active/Active with the existing set of 20 SAS disks. I'm reading through the documentation on NOW[1] on hot-adding shelves and am running into a few questions: - Is the EXN4000 the same as the DiskShelf14mk4? - How do I know if I have ESH2/ESH4 modules or LRC or ESH modules? Also, the NOW documentation[1] refers to the Data ONTAP 7.3 Active/Active Configuration guide for hot-adding of shelves since we are using an Active/Active setup.
