The error message "pool has no desktops available" suggests that the pool of virtual desktops could not be accessed by some users during the maintenance activity. The issue can be caused by various factors, but three possible reasons are listed below:
A. SQL Server was down: If the SQL Server used by the VMware Horizon infrastructure is down, then it can cause the issue where some users are unable to connect to the virtual desktops. SQL Server is responsible for maintaining the VMware Horizon database that stores the information about pools, desktops, and user sessions. If the SQL Server is not accessible, then the users may not be able to connect to their assigned desktops.
B. VMware Composer Server was down: VMware Composer is a component of the VMware Horizon infrastructure that is used to manage the creation and maintenance of linked-clone virtual desktops. If the VMware Composer Server is down, then it can cause the issue where some users are unable to connect to the virtual desktops. The Composer Server is responsible for creating and managing linked clones of the virtual desktops, and if it is not functioning correctly, then the pool of virtual desktops may not be available for some users.
C. View Connection Server was down: View Connection Server is the main component of the VMware Horizon infrastructure that is responsible for managing the connections between the virtual desktops and the clients. If the View Connection Server is down, then it can cause the issue where some users are unable to connect to the virtual desktops. The Connection Server manages the user sessions and the pool of virtual desktops, and if it is not functioning correctly, then the users may not be able to access their assigned desktops.
D. vCenter Server was down: The vCenter Server is the central management component of the VMware infrastructure that is used to manage the virtualization environment. If the vCenter Server is down, then it can cause the issue where some users are unable to connect to the virtual desktops. The vCenter Server is responsible for managing the virtual machines that host the virtual desktops, and if it is not functioning correctly, then the users may not be able to access their assigned desktops.
E. App Volumes Manager Server was down: App Volumes is a component of the VMware Horizon infrastructure that is used to manage the deployment of applications to the virtual desktops. If the App Volumes Manager Server is down, then it can cause the issue where some users are unable to connect to the virtual desktops. The App Volumes Manager Server manages the applications that are deployed to the virtual desktops, and if it is not functioning correctly, then the users may not be able to access their assigned desktops.
In summary, the possible reasons for the failure are related to the critical components of the VMware Horizon infrastructure such as SQL Server, VMware Composer Server, View Connection Server, vCenter Server, and App Volumes Manager Server. If any of these components are not functioning correctly, it can cause the issue where some users are unable to connect to the virtual desktops.
