Updating a vCloud with only one cell


In this recipe, we will learn how to update a vCloud that has only one cell.

Getting ready

We need a vCloud with only one cell and downtime to bring it down. Make sure you have e-mails configured in vCloud.

How to do it...

  1. Log in to vCloud as SysAdmin.

  2. Navigate to Manage & Monitor | Provider VDCs.

  3. Right-click on each PvDC and select Notify... as shown in the following screenshot:

  4. Enter a title for the notification e-mail into Subject.

  5. Enter a text that describes to the users in easy terms why, when, and how long you plan to shut down the cells. Also, it always helps to put a sentence in about how this downtime helps them.

  6. Shut down the cell. See the A scripted cell shutdown recipe in Chapter 5, Working with the vCloud API.

  7. Do your maintenance on the vCloud Cell.

  8. Start the cell with service vmware-vcd start.

  9. Wait until vCloud is fully up.

  10. Go back to the PvDCs and send out another notification that vCloud is accessible again.

How it works...
