Remove the E1.L SSD

To replace a failed SSD, you must remove the SSD from the CERES DBox , which could cause a data rebuild to occur, resulting in degraded performance.

You can avoid degrading the performance by deactivating the SSD before removal. Deactivating copies the data from the defective SSD to other SSDs and stops the cluster from using the defective SSD. When you remove a deactivated SSD, no data rebuild occurs and there is no impact on the cluster's performance.

Deactivate the SSD in advance of replacing the failed SSD via VAST CLI or VAST Web UI.

Deactivation can take several hours and removes the SSD's capacity from the cluster. Initiate deactivation approximately 24 hours prior to a scheduled SSD replacement to be sure the deactivation completes before the replacement.

After you replace the SSD into the CERES DBox, you must activate the SSD to restore its capacity to the cluster.

To deactivate and remove the applicable E1.L SSD:

  1. Connect to the VAST Web UI and do either of the following:

    1. From the menu, (click menu_button.png ), select Infrastructure > SSDs. Select ( 3dots_menu.png ) More actionsat the right side of the SSD to deactivate, and select Deactivate.

    2. You can also (click menu_button.png ), select Hardware Layout, select the necessary SSD from the graphical view and click Deactivate_Icon_VMS.png in the right pane to deactivate it.

  2. Click Yes to confirm you want to deactivate the SSD. Deactivation begins and the progress is displayed in the Activities page, which you can navigate to, from the menu.

    If you initiated the task from the Infrastructure page, the Activities icon appears at the top of the page, showing that the deactivation task is in progress. When the task is complete, a message appears at the bottom right of the page.

    You can also deactivate the SSD from the VAST CLI (see VAST CLI Commands for Deactivating and Activating SSDs.)

  3. Press the latch (1) to release the tray lever on the E1.L solid state drive, as shown in the figure given below.

  4. Rotate the tray lever (2) to the horizontal position as shown above.

  5. Pull the tray lever (2) to remove the SSD (3) from the enclosure.

  6. Return the tray lever (2) to the closed position.

  2. Insert the SSD fully into the enclosure.

  3. Push the latch (3) inwards.

  4. Return the tray lever (2) to the closed (vertical) position.

    Activate the applicable SSD.

  5. To activate the SSD from the VAST Web UI, select Hardware Layout from the menu, click the necessary SSD in the diagram and click the activate button (Activate_button.png). You can also activate any SSD from Infrastructure > SSD.

    The activation task commences and the progress is displayed in the Activities page, which you can access from the menu.

    You can alternatively activate the applicable SSD from the VAST CLI (see VAST CLI Commands for Deactivating and Activating SSDs.)

 

VAST CLI Commands for Deactivating and Activating SSDs

Use the VAST CLI commands given below as an alternative method to deactivate and activate the SSD.

  • To list the SSDs, run the ssd list command.

    For example:

    vcli: admin> ssd list --dbox-name DBox1

  • To deactivate the SSD, run the ssd deactivate command.

    For example:

    vcli: admin> ssd deactivate --id 2

  • To activate the SSD, run the ssd activate command.

    For example:

    vcli: admin> ssd activate --id 2
