The only time that you should remove a data disk from a storage system is if the disk is not functioning correctly. If you want to remove a data disk so that it can be used in another system, you must convert it to a hot spare disk first.
You can cause Data ONTAP to fail the disk immediately or allow a disk copy to finish before the disk is failed. If you do not fail the disk immediately, you must wait for the disk copy to finish before physically removing the disk. This operation might take several hours, depending on the size of the disk and the load on the storage system.
Do not immediately fail a disk unless it is causing immediate performance or availability issues for your storage system. Depending on your storage system configuration, additional disk failures could result in data loss.
|Can wait for the copy operation to finish (recommended)||Enter the following command to pre-fail the disk: disk fail disk_name
Data ONTAP pre-fails the specified disk and attempts to create a replacement disk by copying the contents of the pre-failed disk to a spare disk.
If the copy operation is successful, then Data ONTAP fails the disk and the new replacement disk takes its place. If the copy operation fails, the pre-failed disk fails and the storage system operates in degraded mode until the RAID system reconstructs a replacement disk.
|Need to remove the disk immediately||Enter the following command to cause the disk to fail immediately: disk fail -i disk_name
The disk fails and the storage system operates in degraded mode until the RAID system reconstructs a replacement disk.
