How are you seeing this mis-alignment? What are the numbers? How big
is the lun? What OS is using the LUN? Looking at the docs, VMware is
almost impossible to aligh correctly. There are other issues with
Linux and Solairs, but if you have LVM in place between the LUN and
the filesystem(s), maybe you can build a new aligned LUN and migrate
the data that way?

RE: How to resolve LUN misalignment? [ In reply to ]
Hi John,

Agreed about the signature, nothing I can do about that though!!

It is a SQL LUN which was 7MTT across, it is 12TB in size, about 5TB used.

I know there used to be a way to easily fix this in 7 mode, but cannot find anything on CDOT

RE: How to resolve LUN misalignment? [ In reply to ]
Are you sure it's genuinely misaligned?

Database logging operations almost always set off the misaligned warnings in ONTAP. The only way to be sure is to get the perfstat or just "stats lun" output. There's a quick guide on how to get this data in Appendix B of TR-3633. If you get the "stats start" and "stats stop" data from a time when the database is reasonably active, you'll know whether this is true misalignment or just the usual harmless logging activity.
