Processor Halt Codes Manual

3 Software Halt Code Descriptions
This chapter describes processor halt codes generated by the operating-system software.
Halt code = %nnnnnn
When a millicode halt occurs, look up the halt code in this section. The codes are listed in numeric
order.
For information about recovering a halted processor, refer to Processor Halt Monitoring and
Recovery (page 10). If a system predates or does not have OSM or TSM, these instructions are
invalid. For recovery instructions, contact your service provider or the Global NonStop Solution
Center (GNSC), as directed by your local operating procedures.
Software Halt Code Categories
For all processors, the octal digits of each halt code, bits 0 through 6, identify the type of error
that occurred. Table 3 shows the categories of errors that the operating system detects.
