rmhwconn.1
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 table 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
To disconnect all CEC nodes in node group cec from their HMC nodes:
rmhwconn cec
To remove the connection for Frame node frame1:
rmhwconn frame1
To disconnect all CEC nodes in node group cec from their related hardware serveri, using lpar tooltype:
rmhwconn cec -T lpar
