Removing disks from a node

How you remove a disk from a node depends how the disk is being used. By using the correct procedure, you can prevent unwanted AutoSupport notifications from being generated and ensure that the disk functions correctly if it is reused in another node.

You cannot reduce the number of disks in an aggregate by removing data disks. The only way to reduce the number of data disks in an aggregate is to copy the data and transfer it to a new aggregate that has fewer data disks.

If you are removing a partitioned drive, you must account for how both partitions are being used, and unpartition the drive before you remove it.

If you are removing a disk in a multi-disk carrier, you must take special precautions.
