@TMADOCTHOMAS wrote: I would like to change all of the LUNs created via SnapDrive to space-reserve = disabled for space saving reasons. Any downsides to doing so? This does not save any (physical) space. It simply allows you to over-commit logical space in volume by creating LUNs with total size exceeding volume size. If you over-commit you need to monitor for free space both on logical (volume) and physical (aggregate) level. If you do not over-commit, it is entirely equivalent to having space-reserved LUN. ...

@sroy wrote: Can I safely remove all of the existing lifs including the mgmt lif?  Where do you see it complaining about management LIF? It complains about data LIFs belonging to data SVMs.   @sroy wrote: Can I also remove the root volumes on the FAS-3240 nodes as well and still be able to complete the unjoin procedure?  Again - it complains about SVM root volumes. You obviously cannot remove SVM root volume without losing access to other SVM data volumes (I am not sure it is even possible to remove). What you can do is to move volume to another aggregate on another node.   You cannot remove node root volume. ... View more

@Ontapforrum wrote: 10TB capacity in DS4486/DS4246 is not supported with 8.2.3 7-mode, but with 9.x it is supported. Only in RAID-TEC.   @Ontapforrum wrote: I have never tried it  but I am guessing the system will recognize the disks but will be 'down-sized' to the max-supported disk size supported by that particular OS version type. To correctly recognize disk you need corresponding DQP, my understanding always was that "disk supported starting with Data ONTAP X.Y.Z" simply means "Data ONTAP X.Y.Z includes DQP with this disk". But good question is what happens when you try to create RAID-DP with 10TB disks. Will it be refused flat out or it is "unsupported" in the sense "we do not recommend it". ... View more

It should not have any effect on failover (performance). There will be one path to internal disks from each controller, but I find it acceptable given that all connections are via fixed backplane. ... View more

@netappmagic wrote: Make sense? No. You cannot remove nodes that host volumes. If volumes are already relocated to another nodes, any traffic to LIFs on these nodes will go via interconnect to another node(s). So moving LIFs to nodes that actually host volumes will actually improve situation by avoiding indirection via cluster interconnect. ... View more

Older version may not be able to access disks used by newer version. So before directly installing 9.3, remove all aggregates, unpartition disks, if possible, zero spares (not sure if it works from maintenance mode) and unassign disks.   Once I observed old version crashed when booted on new firmware. I had to downgrade firmware as well.   So doing official revert is more fool proof, but requires working cluster and takes more time. ... View more

@General wrote: This is 7-mode, verion 8.2. [Disks] were partitioned 7-Mode never supported partitioned disks. It sounds like you tried to sanitize root aggregate which you cannot do for obvious reasons. Now you are left without root volume/aggregate. If this is HA pair and partner still works you may try to complete sanitize from partner. If this is standalone controller, it may be possible to do it from network boot, but I am not sure if it will work.   Or you may try to initialize disks and install Data ONTAP again and follow https://kb.netapp.com/app/answers/answer_view/a_id/1034477/loc/en_US ...

If these are new systems, it is faster to simply install another version. Use special boot menu 9a to remove existing partitions, then 7 to install desired version (needs HTTP server to download ONTAP from) and then 4 or 9b to initialize. After that join nodes to existing cluster. ... View more
