When you manage a NetApp filer and because of new insights or new organizational names (or even maybe typos) you need to change the names of your volumes and LUNs you might be surprised at how easy that is. I, and I think most Administrators, use FilerView as the main administrative tool. Since there is a rename button for your volumes there I won't talk about that. There ain't however a rename button for your LUNs but there are two easy ways for renaming them without downtime for your storage consumers. The first option is to use the command “lun move” from the commandline, the other one is to use the PowerShell cmd-lets provided by NetApp. See below for more information about these two methods:
Replace a Disk on a NetApp Filer
Summary: How to replace a failed disk on a Netapp Filer.

If you need to replace a disk in one of your netapp filers (for example because it is faulty) you can use the disk replace command:
disk replace start [-f] [-m] <disk_name> <spare_disk_name>
-f: skip confirmation-m: allows mixing disks with different characteristics. It allows using the target disk with rotational speed that does not match that of the majority of disks in the aggregate. It also allows using the target disk from the opposite spare pool.
The disk replace command uses Rapid RAID Recovery to copy data from the specified file system disk to the specified spare disk. At the end of that process, roles of disks are reversed. The spare disk will replace the file system disk in the RAID group and the file system disk will become a spare.
The process can be stopped with:
disk replace stop <disk_name>
NetApp Data Planning

With the introduction of all kind of options in their filers NetApp provides several ways to plan for your data consumption. In this article I'll discuss a few of the most confusing options and clarify them and their interaction with each other by showing an example.
