HP OneView 1.05 User Guide

25.1.2 Roles
• Minimum required privileges: Infrastructure administrator
25.1.3 Tasks
Updating the appliance requires a single user accessing the appliance and causes the appliance
to restart. This does not disrupt the operation of the devices under management, but does result in
an outage of the appliance.
The appliance online help provides information about using the UI or the REST APIs to:
• Determine if a newer appliance update is available. (Minimum required privileges: Read only,
Network administrator, or Infrastructure administrator)
• Update the appliance. (Minimum required privileges: Infrastructure administrator)
25.1.4 Learning more
For more information about obtaining software updates, see “Support and other resources”
(page 247).
25.2 Managing appliance availability
Managing and maintaining appliance availability starts with configuring the appliance virtual
machine for high availability as described in “Planning for high availability” (page 87), and
following the best practices described in “Best practices for managing a VM appliance” (page 176).
In the event of an appliance shutdown, your managed resources continue to operate. For more
information about how the appliance handles an unexpected shutdown, and what you can do to
recover, see:
• “How the appliance handles an unexpected shutdown” (page 177)
• “What to do when an appliance restarts” (page 178)
For information about how to shut down or restart the appliance, see:
• “Shut down the appliance” (page 177)
• “Restart the appliance” (page 177)
25.2.1 Best practices for managing a VM appliance
HP recommends the following guidelines for managing your VM appliance from the virtual console:
Do notDo
• Use thin provisioning.
• Update the VMware tools. If VMware Tools show Out of Date or
Unmanaged, they are running correctly. These status messages are not a
problem, because the tools are available and running. VMware tools are
updated with each HP OneView software update.
• Revert to a VM snapshot (unless under specific circumstances, as instructed
by your authorized support representative).
• Set the Synchronize guest time with host option in the vSphere client when
the HP OneView appliance is configured to use NTP. HP OneView
automatically sets the appropriate Synchronize guest time with host setting
during network configuration. When HP OneView is configured to use NTP
servers, the Synchronize guest time with host option is disabled. If HP
OneView is not configured to use NTP servers, it synchronizes to the host
VM clock and the Synchronize guest time with host option is enabled. In
this case, configure the VM host to use NTP.
• Reduce the amount of memory assigned to the VM.
• Use thick provisioning.
• Use shares and reservations to
ensure adequate CPU performance.
