Once you have provisioned a new LUN (or Symmetrix device), you have to scan for this LUN from Celerra/VNX file components to make use of it at the File side – for making filesystem and then CIFS share/ NFS export. Here we are discussing the simple steps to scan the new LUN.
1. From the GUI – Unisphere Manager
2. Now via CLI
From the CLI we have to scan for the new LUN on all data movers. We will use the command server_devconfig. We can run the command for each DM (data mover) separately starting with the standby one first. The syntax for a dual data mover system will be,
server_devconfig server_3 -create -scsi -all # for standby DM
server_devconfig server_2 -create -scsi -all # for primary DM
This is the recommended way but I have never heard of any issue occurred while scanning across all DMs at a time.For a multi DM system if we want to scan for all data movers in single command, the only change will be just ALL in the place of the server name.
server_devconfig ALL -create -scsi -all # for all DMs
After the successful scanning you can find the new devices/LUNs at the bottom of the output of nas_disks -list command.

You can verify the increased space of the respective pool by running the nas_pool -size [Pool Name].
