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.
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.
