Correcting problems powering on a logical server
Occasionally a Virtual Connect logical server or virtual machine logical server fails to power on
and returns an error. If you encounter this problem, check the firmware versions and hardware
as described below.
Suggested action: Check firmware versions Check the recommended firmware versions of
Virtual Connect Manager, Onboard Administrator, Integrated Lights Out (iLO) and server blade
BIOS. A firmware version different than the recommended version could cause a power request
to fail.
Suggested action: Check hardware using Onboard Administrator Most power issues are related
to the hardware itself. For example, power problems can be caused by temperature, fan speed,
fans not installed in an effective configuration, insufficient power because of power supply
location, Blades and Interconnect Modules health problems, or device failure errors in general.
These problems can be identified using the Onboard Administrator Rack Overview page (available
in HP SIM through Integrated Manager) or Onboard Administrator Insight Display.
The Rack Overview page provides error icons that identify the system status. Critical and major
errors influence power requests and should be corrected quickly. For more information, see the
“Enclosure Power Management” section of the HP BladeSystem c-Class Onboard Administrator
User Guide at

c00705292.pdf .
Suggested action: Check disk space When you create a Hyper-V virtual machine logical server,
if the amount of free disk space on the VM Host is smaller than the amount of memory chosen
for the logical server, the logical server cannot be powered on. This occurs infrequently, because
free disk space is usually larger than memory size.
To successfully power on a logical server, your data store size should be equal to or greater than
the VM disk size plus the VM memory size.
When you have enough free disk space on the data store, try using HP SIM to power on the
logical server. Select the VM node and click the power on button.
Errors accessing single sign-on iLO or Onboard Administrator
In some cases, when you click the technology icon for a Single-Sign-On configured iLO or Onboard
Administrator, you are required to manually login, or the browser returns a "404 Not Found"
error.
Workaround Login to the iLO or Onboard Administrator, ensure that all necessary licenses
are applied and HP SIM Single-Sign-On is properly configured. Then rediscover the iLO or
Onboard Administrator on the Central Management System.
Logical server operations cannot be cancelled
After a logical server operation is started, you can view its status on the Report
→Logical Server
Job Status... screen, but you cannot cancel it. Running jobs do not time out. If a job seems to be
running for a long period of time (more than two hours), the job may have completed but some
issues may have been encountered with the underlying software. The job will continue to run
and the logical server will be locked. The lock is released on the next restart of the Logical Server
Automation service.
Do not stop or restart Logical Server Automation service while operations
are in progress
Unpredictable results can occur if you stop or restart the LSA service while logical server
operations are in progress.
“Error saving storage pool entry after Logical Server Automation
service is restarted” is an example of one such result.
