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
```

FILES

$XCATROOT/bin/rmhwconn

(The XCATROOT environment variable is set when xCAT is installed. The default value is “/opt/xcat”.)

NOTES

This command is part of the xCAT software product.
