Set the "Partition start policy" to either "Auto-Start Always" or "Auto-Start for Auto-Recovery". Click properties, then the "Power-On Parameters" tab.Ĭ. On the HMC, expand Systems Management, Servers and select the server.ī. POWER 7 servers, POWER 6 servers with server firmware Ex350 and HMC Version 7 release 7.3.5 or laterĪ. If a user selects power on to "standby" then this step will need to be repeated to set the next IPL to running otherwise the server halts the IPL at standby. Note: Each time a user "power on" operation is performed on the server this setting will change to the power on option the user selected. Set Boot to system server firmware to Running.
POWER 5 servers POWER 6 servers with server firmware Ex340 and earlier and HMC Version 7.3.4 and earlierĪ. Enable auto power restart for the partitions Sign in as admin (the user ID is lowercase).Ģ.
For information on how to access ASMI, refer to the IBM Systems Hardware Information Center at.
Launch the Advanced Management System Interface (ASMI) menu. Enable Auto Power Restart on the server a. To enable restart for all partitions after an AC power loss, perform the following:ġ. If the Advanced Management System Interface (ASMI) is set to automatically start after a power loss and the server 's partition start policy allows it, then any partition that was powered down while on battery power (for example, a power handling program or a system value time limit after the UPS power loss signal) or was up and running when the power failed is restarted automatically. VLOG dump identifier 0100054A has more information about the problem.
Return code X'00F0' was received from the service processor. V5R4M0: CPF1221 Service processor failed. V5R4M5: CPF18B4 QPWRRSTIPL cannot be changed in secondary partition.
V6R1M0: CPF18B4 QPWRRSTIPL cannot be changed in secondary partition. V7R1M0 and later: CPF18B4 QPWRRSTIPL cannot be changed in partition. If a user attempts to change the value for the QPWRRSTIPL system value on a partition running on a HMC managed server, the change operation will fail with the following message: The restart behavior is controlled by two settings: the server's auto power restart option and the server's partition start policy setting.
In a double boot, the PC will power on for about two seconds, off for about a second, turn back on, display the POST screen, and then continue to boot up normally.On HMC managed POWER servers, the IBM i QPWRRSTIPL system value does not control the restart behavior. Even after the computer is turned off, these parameters will not need to be re-entered for as long as the power supply is still receiving power. If the computer did not have any power and had just been plugged in, the same parameters would need to be implemented again, and since these parameters require a reboot, the computer will do a quick reset to implement the parameters that are set in the BIOS. At such times, a reboot will be required. ( Learn how and when to remove this template message)ĭouble boot (also known as cold double boot, double cold boot, double POST, power-on auto reboot, or fake boot) is a feature of the BIOS, and may occur after changes to the BIOS' settings or the system's configuration, or a power failure while the system was in one of certain sleep modes.Ĭhanging some parameters in the BIOS will cause this issue, even for items as simple as initializing the current CPU and memory clocks.
