vmware userland file-level restores (vmdks on nfs + smvi)
by Nick Silkey 14 May '09

14 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Toasters -- Our bare-metal systems[1] are able to self-service themselves with TSM clients to perform file-level restores. There is a push to standardize on VMWare to replace the kit behind a lot of the low-hanging fruit Windows/Linux x86 systems. But theres a desire to not reduce function regarding file-level restores with the introduction of this new VMWare platform. We dont want to stick TSM clients on these guests due to redundant backup data shuffling over to pricy FC 3Par disk and the inordinate I/O load on the guests impacting ESX. We want to find a crafty means to leverage crash-consistent snaps on the NetApp (ala, SMVI) which is hosting all the vmdks in order to source restores, but no one is able to order the steps and pieces in such a way that allows people to self-service file-level restores. Theres been talk of craziness of exporting/serving snaps of vmdks to staging guests which can then browse the vmdk to pluck out files and other such hoop-jumping ... but this far from an elegant, scalable solution. The NetApp hosting VMWare serves VMDKs via NFS (3160 under 7.2.6.1). A-SIS and SMVI are components in this architecture as well. If anyone has crossed this path before, insight is appreciated. Thanks. [1]: Windows, Linux, AIX, Solaris, and Tru64 ... oh my. - -- Nick Silkey -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAkoMKrQACgkQrDQjhjXrMeK++wCfZdTkxRUFpWVM7caUatOcC5wp GlQAn0amnstES04kngn9wyKNyb8RbHGg =QjuQ -----END PGP SIGNATURE-----

Any luck with SnapMirror & ESX LUN's ?
by Raj Patel 14 May '09

14 May '09

Hi, Anyone used SnapMirror successfully with ESX LUN's ? I realise it will only be a crash-consistent copy and I have to enable LUN re-signaturing for ESX to pick it up but this seems like a handy way for me to backup a few DMZ VM's on a LUN (on a seperate secured iSCSI vlan) to another LUN on the same SAN. Cheers, Raj.

snapmirror retrieve - multiple sites from one tape
by John Stoffel 07 May '09

07 May '09

Hi, We're starting to use snapmirror to help us migrate some data from old to new filers at sites. We're also going to use it to setup from snapmirror relationships across the WAN as well. What we'd like to do is make one tape on the source side, then ship that one tape to each of the destination sites, do the snapmirror store <vol> <drive> - ship to <dest> dest> snapmirror retrieve <vol> <drive> dest> snapmirror update -S <src>:<vol> <dest>:<vol> - ship to <another> another> snapmirror retriev <vol> <drive> another> snapmirror update -S <src>:<vol> <another>:<vol> Is this possible? It's not clear from the docs if you can do this. Hmm, looking at the Data Protection Using Snapmirror documentation, it looks like the base snapshot created by the 'store' command sticks around, and could be used for other snap mirror relationships, since it has to be manually deleted down the line. Any clarification would be appreciated. Thanks, John John Stoffel - Senior Staff Systems Administrator - System LSI Group Toshiba America Electronic Components, Inc. - http://www.toshiba.com/taec john.stoffel(a)taec.toshiba.com - 508-486-1087

NetApp3140 v EMC CX4-240

I am after opinions / Pros and Cons on running a substantial VMware infrastructure of approximate 200+ VMs using the 2 mentioned storage systems. Obvious benefits of the NetApp seem to be around the De-Dupe out of the box. Any other thoughts / experiences would be appreciated Fibre attached Dell R900s will be running the ESX side of things.

Re-exporting your /etc/exports - how do I get a change in order of shares to take effect?
by Page, Jeremy 05 May '09

05 May '09

I have several NFS mount points that also have child directories also exported and I've been told that you should export the parent directories first, then the children. I've updated my /etc/exports file and ran exportfs -r on the filer but it does not look like it's taking effect if I do an exportfs to see what's currently exported. How do I get the exports in the correct order? Please be advised that this email may contain confidential information.

Re: Warning for people doing a head upgrade from a 3050 to a 3170
by Romeo Theriault 01 May '09

01 May '09

> > I dont think the issue here, is that netapp doesnt document where to > download the PROPER version of ONTAP. Agreed. I think my biggest issue is that I misinterpreted the documentation. In the docs when it say's : Go to the NOW site at http://now.netapp.com/NOW/main/software.shtml and > download the version of Data ONTAP for your existing system that matches the > version installed on the FAS31xx system. > I interpreted this as meaning download the version for your existing system (3050 in my case) that matches the version installed on the FAS3170, which I assumed meant the version number (7.2.6.1) in my case. But..ya think you're reading "upgrade version" a little too...narrowly? Yes, I guess I was. How can Netapp prevent this chain of errors? I would say by doing what you and I have both suggested. Amending the documentation to unambiguously state what they really want to happen. -- Romeo Theriault System Administrator Information Technology Services

I stated in the original message: The documentation states that you need to bring the 3050 heads up-to the > same software level as the 3170 heads. If you read the rest of the doc it says this: *If your FAS3020 or FAS3050 system has... * *Then...* The same version of Data ONTAP as the FAS31xx system Go to Step 3. A version of Data ONTAP different from the one on the FAS31xx system Go to Step 2. Step 3 is to continue with the install, Step 2 is to upgrade the *version*of OnTap to the level of the FAS3170. To me version says software level, not different binaries for the different arch. Besides, step 3 is to continue with the install. Under what case would you have a 3170 build of OnTap on your filers before you start an upgrade? All of this tilted towards making me believe that they were concerned with the software version on the heads. If this is not the case it needs to be made clear.

Warning for people doing a head upgrade from a 3050 to a 3170
by Romeo Theriault 30 Apr '09

30 Apr '09

Here is a warning for people that might be doing a head upgrade from a 3050 to a 3170 (and possibly other heads). The documentation states that you need to bring the 3050 heads up-to the same software level as the 3170 heads. This may very well be the case but they fail to mention that the 3170 uses a different build of OnTap and that you need to upgrade OnTap on the 3170's immediately after the upgrade with the build for the 3170's. So right now we are running 3170's with a build of OnTap 7.2.6.1 built for the 3050's and getting these errors in syslog: na1-u-e0a [na1-u: mgr.stack.openFail:warning]: Unable to open function name/address mapping file /etc/boot/mapfile_7.2.6.1.2O: No such file or directory Netapp Supports response is: "Upgrade or you'll probably get Kernel Panics." and "We'll try to update the documentation." Needless to say I'm not impressed. -- Romeo Theriault System Administrator Information Technology Services
