On two recent deployments our team ran into some issue when trying to create pools with file shares created on an EMC NAS device. The install wizard was not seeing those folders as setup properly so it could not complete the install. All the permissions were checked best we could see, but it still did not like the share configuration.
I decided to try creating the shares on one of the front end servers and moving on with installation, I then would xcopy the data over to the EMC NAS, and then modify the file locations for the pool.
There is a great article here that goes over the bulk of this migration process, the one difference for my situation is the xcopy from windows share over to the EMC device.
In my example my file shares were in D:OCS Shares on local folder and I had mapped the folder on the EMC containing all of the OCS Shares to Z:
xcopy “d:ocs shares” z: /e /k /o /x /y
This basically will copy everything in the D:ocs shares folder, including sub directories and files to the Z: drive.
All attributes, including all ACL information will be kept, and it will not prompt to overwrite any existing files.
Once we completed this xcopy, we followed the instructions in the above link to modify all WMI settings and all IIS settings, from there we were able to restart services and verify all functionality.
Obviously there is a way to get the EMC NAS file shares setup correctly, however I did not have this knowledge, and as a time saver, this was the best fix for me.
