Question
Which command will dispalys path status for device defined on a specific channel?
A. D M=CHP
B. D M=CHP()
C. DS P
D. D M=CONFIG()
Answer
B. D M=CHP()
Explanation
The D M=CHP() command is used to display the path status for devices defined on a specific channel path (CHP) in a z/OS mainframe environment.
Here’s a more detailed explanation:
- D is the display command
- M= specifies that you want to display information about a specific type of resource
- CHP indicates you want to display channel path information
- The parentheses () after CHP allow you to specify a particular channel path ID
So D M=CHP() lets you view the status of devices and paths associated with one specific channel by providing the channel path ID in the parentheses.
The other options are incorrect because:
A) D M=CHP without parentheses would try to display info for all channel paths, not a specific one
C) DS P is not a valid z/OS display command
D) D M=CONFIG() displays general I/O configuration information, not path details for a particular channel
Therefore, D M=CHP() is the right command to display the path status for devices on a single, specified channel path. Mastering commands like this is key to managing z/OS I/O configurations and excelling as a mainframe systems programmer.
