You can use the system values discussed in this topic to control the type of initial program load (IPL) and the way the system does an IPL.
You can now work with all system values in iSeries™ Navigator. To work with system values in iSeries Navigator, select your system . If you do not have an iSeries Navigator connection, you can still use these system values through the character-based interface. From the character-based interface, change or display these values using the Work with System Values (WRKSYSVAL) command.
The Allow scheduled restart (QIPLDATTIM) system value sets the date and time for a scheduled restart. In iSeries Navigator, select your system .
To set the date and time format, use the Date and Time (QDATFMT, QDATSEP, QTIMSEP) system values.
The Previous restart type system value displays the way the system did the last IPL. You cannot change this system value. In iSeries Navigator, select your system . When needed, use the help associated with the display.
| Operator panel restart (0) | The restart operation occurred when requested from the operator panel or from Dedicated Service Tools (DST) for a secondary partition. |
|---|---|
| Automatic restart after power restored (1) | The restart operation occurred automatically when power was restored after a power failure. You can specify this type of restart operation in the Restart options on the General page. |
| Restart (2) | The restart operation occurred when a user requested turning off the system and restarting it. |
| Time-of-day restart (3) | The restart operation occurred automatically on the date and time specified for Scheduled restart on the General page. |
| Remote restart (4) | A remote restart operation occurred. You can specify this type of restart operation in the Restart options on the General page. |
The Type of restart system value defines the type of IPL the system does from the control panel. In iSeries Navigator, select your system . When needed, use the help associated with the display.
| Unattended (0) | An unattended IPL. No displays requiring user interaction are shown during the restart. The normal signon display is shown when the restart is complete. If the system is in manual mode, an attended IPL is performed instead. |
|---|---|
| Attended (1) | An attended IPL. Start the system with an operator. All dedicated service tools functions are available along with the full set of restart displays. An unattended IPL is done if it is done remotely, by date and time, or after power failure. |
| Attended, console in debug mode (2) | An attended IPL in debug mode. Restarts the system and leaves the controller QCTL and device QCONSOLE varied on. Select this only for problem analysis, as it prevents other devices on the workstation controller from being used. |
With the Automatically restart after power failure system value, you can specify whether to allow auto-restart when a power failure occurs. In iSeries Navigator, select your system . When needed, use the help associated with the display.
| Not selected (0) | Does not do an automatic restart after a power failure. |
|---|---|
| Selected (1) | Does an automatic restart after a power failure. |
Use the Allow remote power-on and restart system value to start the remote system by using your telephone and a modem or the system power control network (SPCN) signal. This means that any telephone call causes the system to restart. In iSeries Navigator, select your system . When needed, use the help associated with the display.
| Not selected (0) | Does not allow a remote restart. |
|---|---|
| Selected (1) | Allows a remote restart. |
The When power failure occurs (QUPSDLYTIM) system value controls the length of time the system waits before saving main storage and turns off the system. If utility power is restored before the time ends, the system ends the timer. If the timer ends first, the system begins to save main storage or goes into continuously powered main storage (CPM). In iSeries Navigator, select your system .
There are five choices for the QUPSDLYTIM value.
| Automatically power down the entire system (0) | The system automatically turns down when system utility power fails. |
|---|---|
| Power down system after time interval (1-99999) | Specifies the delay time in seconds before the utility power fails. |
| Power down system, retain power on main tower (*BASIC) | Turns down only the processor, I/O processor cards, and load source storage. The appropriate wait time, in seconds, is calculated. (This must be used only if you have the battery power unit or an uninterruptable power supply without every rack being connected.) |
| Power down system, system calculates delay time (*CALC) | The appropriate wait time (in seconds) is calculated. This value must be used only if you have a 9402 or 9404 system with a battery power unit. |
| Do not automatically power down system (*NOMAX) | *NOMAX is used when a user supplied program is controlling the turning down of the system or a generator is providing unlimited power. The system does not start any action on its own. |
Use the Message queue and library system value to specify where you want your messages sent when the power to the system is interrupted. The default values are QSYSOPR for the Message queue and QSYS for the library. In iSeries Navigator, select your system . When needed, use the help associated with the display.
This system value sends the messages to the system operator's message queue when power to the system is interrupted.
| Message queue | Specifies another message queue (in addition to the system operator's message queue) where messages are sent when power to the system is interrupted. |
|---|---|
| Library | Specifies the library where the other message queue is located. |
