Attention

• To ensure that there is adequate system cooling, do not operate the solution for more than two minutes without either a drive or a filler panel installed in each bay.

• Before you make changes to the drives, back up all important data stored on them.

• If one or more NVMe solid-state drives need to be removed, disable them in the OS before removing them.

Procedure performed by: customer or field service

To remove a hot-swap drive, complete the following steps:

1. To open the drive tray handle, press the tab.
   Figure 1. Hot-swap drive removal
   
   
2. Grasp the handle and slide the drive out of the drive bay.

3. Check the status of the RAID array to verify that slot 5 is empty:

   # /usr/share/tacp/lenovo/tacp-nvme-control.py -display

   The output shows that there is no drive in slot 5.

4. Check that the NVME namespace to verify that nvme3 is deleted:

   # ls -l /dev/nvme

   Following is an example output:

   crw-------. 1 root root 243, 0 Aug 20 11:02 /dev/nvme0
   crw-------. 1 root root 243, 1 Aug 20 11:02 /dev/nvme1
   crw-------. 1 root root 243, 2 Aug 20 11:02 /dev/nvme2
   crw-------. 1 root root 243, 4 Aug 20 11:02 /dev/nvme4
   crw-------. 1 root root 243, 5 Aug 20 11:02 /dev/nvme5
   crw-------. 1 root root 243, 6 Aug 20 11:02 /dev/nvme6
   crw-------. 1 root root 243, 7 Aug 20 11:02 /dev/nvme7
   

   The output shows that there is no nvme3.

The removal of the hot-swap drive is now complete.

After removing the hot-swap drive:

• Install a drive filler or a new drive to cover the drive bay. See Installing a hot-swap drive.

• If you are instructed to return the component or optional device, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
