Procedure
1. Verify that all servers are switched off.
2. Start all storage systems, beginning with the expansion enclosures.
Wait until the disk LEDs on all of the expansion enclosures have stopped blinking
(which indicates that they are spinning up) or two minutes, whichever comes first,
then start the storage system RAID controller enclosures. Note that the disk drives
in some storage enclosures do not spin up until commanded to do so by the RAID
controller, so the LEDs may continue to blink until after the RAID controller
enclosure has sent those commands and the drives have spun up.
3. For a cluster configuration, verify the virtual SMU has been installed and configured
in the customer VMware or HyperV environment.
Wait one minute to allow the external SMU to start.
4. If you are starting a cluster, wait 5 - 10 seconds before powering on the next node in
the cluster.
Recovering from power stand-by
When the server is in a power stand-by state, the power supplies are powered and the
PSU LEDs are lit, but the Power Status LED on the rear panel is not.
The server enters a stand-by power state due to any the following conditions:
■
The
shutdown --powerdown
command has been issued.
■
The PWR button is pressed when the server is running.
■
The server has shut down automatically due to an over-temperature condition.
You can restore the server to its normal power state by either of the following methods:
■
Press the PWR button.
■
Remove the power cables from both PSUs, wait for 10 seconds, then reconnect the
cables to the PSUs.
