<strong>CP</strong>U cpuaddr<br />

<strong>CP</strong>U cpuaddr1-cpuaddr2<br />

<strong>CP</strong>U ALL<br />

specifies the processor or processors you want to place in hard stop. You can<br />

specify a single processor address, a list of processor addresses delimited by<br />

blanks, a nonwrapping pair of addresses separated by a hyphen (-) with no<br />

blanks, or ALL. If you omit this oper<strong>and</strong>, all of your virtual processors are placed<br />

into soft stop.<br />

1. If you enter the STOP comm<strong>and</strong> without oper<strong>and</strong>s, all of your virtual processors<br />

are placed into soft stop.<br />

2. This comm<strong>and</strong> is useful with a TRACE comm<strong>and</strong> to suspend execution when a<br />

certain condition is reached.<br />

3. Execution of the virtual processor or processors is suspended until a BEGIN,<br />

SYSTEM RESTART, ATTN, IPL, EXTERNAL, or REQUEST comm<strong>and</strong> is<br />

entered.<br />

4. The STOP comm<strong>and</strong> causes suspension of virtual machine execution,<br />

regardless of the SET RUN setting.<br />

H<strong>CP</strong>6026E The comm<strong>and</strong> comm<strong>and</strong> for <strong>CP</strong>U nn is<br />

invalid because the <strong>CP</strong>U is in<br />

check-stop state.<br />
