In this recipe, we will learn how to update a vCloud that has only one cell.
We need a vCloud with only one cell and downtime to bring it down. Make sure you have e-mails configured in vCloud.
Log in to vCloud as
SysAdmin
.Navigate to Manage & Monitor | Provider VDCs.
Right-click on each PvDC and select Notify... as shown in the following screenshot:
Enter a title for the notification e-mail into Subject.
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.
Shut down the cell. See the A scripted cell shutdown recipe in Chapter 5, Working with the vCloud API.
Do your maintenance on the vCloud Cell.
Start the cell with
service vmware-vcd start
.Wait until vCloud is fully up.
Go back to the PvDCs and send out another notification that vCloud is accessible again.
