It's been suggested to me (by a DB vendor) to use Oracle ASM to manage the disks presented to Linux for our servers hosting Oracle DBs. The disks are hosted on a C-Mode 9.7 array (All Flash). I cannot see the benefit of this with an all flash array. (RAID10 DP and WAFL). ASM seems to utilize stripping at the OS layer and manages the disk groupings. Perhaps on a very I/O intensive workload this would be beneficial but with our NetApp array being all flash seems to me to needlessly complicate matters.   Some aspects of ASM that concern me: Does NetApp Snapcentre 4.4. suppor t it (seems to) Does this tie the disk to only the Oracle layer i.e. seems like you cannot write an arbitrary file to these disk with using ASM tooling?  What is the impact for other tools (AV, backup tools) Other aspects? I'd be very interested to here from people that are using ASM with NetApp arrays and what their use cases were. ... View more

I am snapmirroring volumes from a 8040 FAS to our new AFF that tiers to a Storage Grid. We want to get all of the volumes onto the AFF and retire the FAS. We have 2 aggregates on the AFF. When I create the snapmirror protection group using the GUI on the source (FAS), it always puts the destination volume on the same aggregate on the AFF. So now the 1st aggregate is full and the 2nd aggregate has 0 volumes on it.  Shouldn't the snapmirror protect process choose the aggregate that has less volumes and more free space? I don't think I should have to continually move destination volumes around and I don't think I should have to manually create a dp volume and then run it via command line. Any ideas why it's not using the empty aggregate?  ... View more

From SMB2.0 it is only possible to access the ~snapshot folder from an ONTAP junction point. In SMB1 the ~snapshot tree could be entered at any folder. This is described here: https://library.netapp.com/ecmdocs/ECMP1196891/html/GUID-6D832809-1E60-4041-BF08-D390CB6B3D89.html    I have found that if I take a UNC, append \~snapshot to it and map that to a drive letter it works but has anyone got a more elegant solution? Is there a freeware tool that will give access to the ~snapshot tree at an arbitrary  place in the hierarchy?  I don't want to subvert security.   Thank you ... View more

I'm wanting to turn on SMB2 on my netapps that are running SMB1 now.   WIndows 10 is our OS and can mount CIFS fine on SMB1 right now. I went to options enable smb2 on and that worked but then no WIndows10 systems could mount cifs shares.  So i turned if off and we are back to being able to mount the cifs shares.   Not sure what to make of that.  Did i miss something?! ...
