Hot adding a drive shelf

You can add a new drive shelf while power is still applied to the other components of the storage system. You can configure, reconfigure, add, or relocate storage system capacity without interrupting user access to data.

Due to the complexity of this procedure, the following is recommended:

  • Read all steps before beginning the procedure.
  • Ensure hot adding a drive shelf is the procedure you need.

This procedure applies to hot adding a DE120S, DE240S, or DE600S drive shelf to a DE2000, DE4000, or DE6000 controller shelf.

  1. Prepare to add the drive shelf
    Before you hot add a drive shelf, you must check for critical events and check the status of the IOMs.
  2. Install the drive shelf and apply power
    You install a new drive shelf or a previously installed drive shelf, turn on the power, and check for any LEDs that require attention.
  3. Connect the drive shelf
    You connect the drive shelf to controller A, confirm IOM status, and then connect the drive shelf to controller B.
  4. Complete hot add
    You complete the hot add by checking for any errors and confirming that the newly added drive shelf uses the latest firmware.
