Pattern error "all commands failed on host" or "all command implementations"

KB Summary by Now Assist

Issue

When running a pattern discovery on a device, one of the following errors are seen:

  • All command implementations  
  • all commands failed on host

For example:

all commands failed on host <IP_ADDRESS>. command type: <COMMAND_TYPE>. command track:
ShellCommand\(NotRelevant),
WindowsShellCommand\(NotRelevant),;input 

The above shows that no command implementation was attempted.

Resolution

Starting from the Jakarta release, the table [sa_mapping_ext_commands] contains the list of commands patterns will execute, and the operating system classes that those commands are relevant for.

In order to relate a command for the a custom class, the following steps must be followed: 

  1. (If a custom class) Create a new record for the new Operating System Class in the [sys_choice] table: 
    1. Navigate to the [sys_choice] table. 
    2. Add a new record with the following details: 
      Table = Mapping Discovery Commands [sa_mapping_ext_commands]. 
      Element = os_class_name. 
      Value = the new table name.  
  2. Add the new class to the desired command: 
    1. Navigate to the [sa_mapping_ext_commands] table. 
    2. Click on the relevant command, for example, Shell. 
    3. Add the new class to the Operating System Class Name list. 

The world works with ServiceNow.
