Starting and Stopping the System Recovering From a System Load Failure

Recovering From a System Load Failure

If a system load is not successful or if the system halts:

1.Check for messages in the System Load dialog box of the OSM Low-Level Link.

2.Check the Processor Status dialog box of the OSM Low-Level Link for halt codes. Look up the halt codes in the Processor Halt Codes Manual for further information about the cause of failure and the appropriate recovery procedure.

3.Check the startup event message window for any event messages. Record the event messages, and refer to the appropriate documentation for recovery information. Refer to the Operator Messages Manual for further information about the cause, effect, and recovery procedure for an event.

4.Check that the disk you selected to load from is in the specified location.

5.Check that the disk is properly configured as a system disk.

6.Correct the problems, and try loading the system again. If you cannot correct the problem, contact your service provider.

7.If you continue to have problems, load the system from each disk path for both the primary and mirror $SYSTEM drives.

8.If you cannot load the system using the current configuration file, load the system using a saved version of the system configuration file. See Configuration File on page 15-8.

9.If you still cannot load the system or if a CONFxxyy is not available, load the system from an alternate system disk if one is available.

10.If you cannot load the system from an alternate system disk, contact your service provider. You might be able to load the system from the CONFBASE configuration file and restore a previously backed-up configuration file. If you use this option, many additional steps are required to restore your system to normal working order.

a.Load the system as described in Starting a System on page 15-5.In the Configuration File box, select Base (CONBASE) as the configuration file.

b.Reload the remaining processors. See Reloading Processors on page 15-12.

c.From the Startup TACL window, configure a tape drive.

d.Restore a previously backed-up configuration file.

e.Load the system as described in Starting a System on page 15-5from the current configuration file (CONFIG). Check that the CIIN file is enabled.

11.After you load a system from a saved version (CONFxxyy) of the system configuration database file or the CONFBASE, verify that no pending changes to system attributes appear. From a TACL prompt:
