NAME

rmhwconn - Use this command to remove connections from CEC and Frame nodes to HMC nodes.


SYNOPSIS

rmhwconn [-h| --help]

rmhwconn [-v| --version]

PPC (with HMC) specific:

rmhwconn [-V| --verbose] noderange

PPC (without HMC, using FSPAPI) specific:

rmhwconn noderange -T tooltype

PPC (use HMC as SFP) specific:

rmhwconn -s


DESCRIPTION

For PPC (with HMC) specific:

This command is used to disconnect CEC and Frame nodes from HMC nodes, according to the connection information defined in ppc talbe in xCAT DB.

Note: If a CEC belongs to a frame with a BPA installed, this CEC cannot be disconnected individually. Instead, the whole frame should be disconnected.

For PPC (without HMC, using FSPAPI) specific:

It's used to disconnection CEC and Frame nodes from hardware server.

For PPC (use HMC as SFP) specific:

It is used to disconnect Frame nodes from HMC nodes.


OPTIONS

-h|--help

Display usage message.

-V|--verbose

Verbose output.

-T

The tooltype is used to communicate to the CEC/Frame. The value could be lpar or fnm. The tooltype value lpar is for xCAT and fnm is for CNM.


RETURN VALUE

0 The command completed successfully.

1 An error has occurred.


EXAMPLES

  1. To disconnect all CEC nodes in node group cec from their HMC nodes:

     rmhwconn cec
  2. To remove the connection for Frame node frame1:

     rmhwconn frame1
  3. To disconnect all CEC nodes in node group cec from their related hardware serveri, using lpar tooltype:

    
     rmhwconn cec -T lpar
