Remove software-encrypted devices from an SDS and remove device encryption

Use this task to remove a device from an SDS and remove the device's encryption. Use this task for both software-encrypted devices and SEDs.

1. Remove the device from the SDS:
   • PowerFlex CLI:

     Use the SCLI --remove_sds_command. For example:

     scli --remove_sds_device --sds_name MY_SDS --device_path /dev/mapper/svm_sdX

     or

     scli --remove_sds_device --sds_name MY_SDS --device_path /dev/mapper/svm_nvmeXn1

   • PowerFlex Manager:

     For more information, see Remove devices.

2. Remove the encryption through CloudLink Center GUI or using the svm erase command:
   NOTE:Removing (erasing) a device from CloudLink destroys all data on the device.

   svm erase <device_name>

   For example:

   svm erase /dev/sdX

   or

   svm erase /dev/nvmeXn0

3. Confirm that the device was erased.
