=head1 DESCRIPTION
|
|
|
|
For PPC (with HMC) specific:
|
|
|
|
This command is used to set up connections for FSP and BPA nodes to HMC nodes. (If the connection already exists, it will not break it.)
|
|
This command is useful when you have multiple HMCs, each of which will manage a subset of the FSPs/BPAs. Use B<mkhwconn> to tell
|
|
each HMC which FSPs/BPAs it should manage. When using this, you should turn off the self-discovery on each HMC. You also need
|
|
to put all the HMCs and all the BPAs on a single flat service network.
|
|
|
|
When -t is specified, this command reads the connection information from the xCAT ppc table (e.g. the parent attribute), and read the user/password from the ppcdirect table. Then this command will assign FSP nodes and BPA nodes to HMC nodes.
|
|
|
|
When -p is specified, this command gets the connection information from command line arguments. If -P is not specified, the default password for FSP and BPA nodes is used.
|
|
|
|
In any case, before running this command, the FSP and BPA nodes need be defined with correct nodetype.nodetype value (fsp or bpa) and nodehm.mgt value (hmc).
|
|
|
|
Note: If a CEC (FSP) belongs to a frame, which has a BPA installed, this CEC should not be assigned to an HMC individually. Instead, the whole frame (BPA) should be assigned to the HMC.
|
|
|
|
For PPC (without HMC, using Direct FSP Management) specific:
|
|
|
|
It is used to set up connections for FSP and BPA node to Hardware Server on management node (or service node ). It only could be done according to the node definition in xCAT DB. And this command will try to read the user/password from the ppcdirect table firstly. If fails, then read them from passwd table. Commonly , the username is HMC. If using the ppcdirect table, each FSP/BPA and user/password should be stored in ppcdirect table. If using the passwd table, the key should be "fsp" or "bpa", and the related user/password are stored in passwd table.
|
|
|
|
When --port is specified, this command will create the connections for FSPs/BPAs whose side in vpd table is equal to port value.

|
|
|
|
=item B<-h|--help>
|
|
|
|
Display usage message.
|
|
|
|
=item B<-t>
|
|
|
|
Read connection information from xCAT DB (ppc and ppcdirect tables). Use this option if you need to connect multiple FSPs/BPAs
|
|
to multiple HMCs in a single command.
|
|
|
|
=item B<-p>
|
|
|
|
The HMC node name. Only one HMC nodes can be specified by this flag. To setup connection for multiple HMC nodes, use flag -t.
|
|
|
|
=item B<-P>
|
|
|
|
The password of HMC based FSP/BPA login user(Default user name is 'HMC'). This flag is optional.
|
|
|
|
=item B<-T>
|
|
|
|
The tooltype is used to communicate to the FSP/BPA. The value could be lpar or fnm. The tooltype value lpar is for xCAT and fnm is for CNM. The default value is "lpar".
|
|
|
|
=item B<--port>
|
|
|
|
The port value specify which side will be used to create the connection to the FSP/BPA. The value could be "0" or "1". If this port value is not specfied in the command, it will use the default value "0". If the port value is "0", in the vpd table, the side column should be A-0 and B-0; If the port value is "1", the side column should be A-1 and B-1.
|

=item B<-V|--verbose>
|
|
|
|
Verbose output.

=item 1.
|
|
|
|
To setup the connection for all FSP nodes in node group fsp to HMC node, according to the definition in xCAT DB:
|
|
|
|
mkhwconn fsp -t
|
|
|
|
=item 2.
|
|
|
|
To setup the connection for BPA nodes in node group frame_grp1 to HMC node hmc1, with password 'abc123':
|
|
|
|
mkhwconn frame_grp1 -p hmc1 -P abc123
|
|
|
|
=item 3.
|
|
|
|
To setup the connections for all FSP nodes in node group fsp to hardware server, and the tooltype value is lpar:
|
|
|
|
mkhwconn fsp -t -T lpar
