addresses or WWN addresses) are used from now on. Also the boot
device priority setting as defined in the VIOM server profile is no longer
valid. The performed init boot results in a power-off state and the server
reports the status “Boot without VIOM” which is also displayed in the
VIOM user interface on the Server Configuration tab in the table col-
umn state. In some situations you may need to manually update this
information in order to get the current state. To do this, click the Update
States button.
Behavior after AC failure
The VIOM-specific virtualization data and inventory data are stored in the
iRMC. This data only remains valid as long as the iRMC is powered on. Dur-
ing a power loss (disconnection of all power cables or power loss in the data
center) the iRMC will forget the VIOM virtualization data as well as the
VIOM-specific inventory data. When AC power returns and the iRMC has
booted again, it still has the following information:
1. This PRIMERGY rack server is managed by VIOM.
2. The VIOM-enabled flag is set.
3. The unique identification of the VIOM installation.
4. The SNMP trap destination as specified by VIOM when managing the
server.
5. Whether VIOM virtualization data was stored in the iRMC before power
loss or not.
If VIOM virtualization data was stored in the iRMC before power loss and
because the iRMC knows that the server was managed by VIOM and that vir-
tualization data was assigned, a special communication process with the
VIOM management station will start when the iRMC is booted again after
power has returned. This communication is based on sending SNMP traps to
the VIOM management station and setting specific status information in the
iRMC. For this process to work, the VIOM management station must be run-
ning and must be accessible to the iRMC.
As long as the iRMC did not receive virtualization data from the VIOM man-
agement station, it will periodically send SNMP traps to the management
