Verifying the Resource Monitoring and Control (RMC) setup

Use this procedure to verify the Resource Monitoring and Control (RMC) setup.

To verify the RMC setup, run the following as the Partition Load Manager user for each of the logical partitions that were used with the plmsetup script. Replace PART_HOST with the name of the logical partitions in the following command:

	CT_CONTACT=PART_HOST lsrsrc IBM.LPAR

If the persistent attributes of the resource class are displayed, then verification is successful.

If the persistent attributes of the resource class are not displayed, try the following steps:

To troubleshoot host or connection errors, complete the following steps.
1. Perform host-based authentication. Complete the following steps:
  1. Run the following command on both the Partition Load Manager server machine and the logical partition.
```
/usr/sbin/rsct/bin/ctsvhbal
```
    A list of identities are displayed. These are identities as which the known partition host can be identified.
  2. Run the following command on both the Partition Load Manager server machine and the logical partition.
```
/usr/sbin/rsct/bin/ctsthl -l
```
    On the Partition Load Manager server machine, there is an entry for the logical partition. On the logical partition, there is an entry for the Partition Load Manager server machine. The HOST_IDENTITY value must match one of the identities listed in the respective ctsvhbal command output.
2. If the HOST_IDENTITY value in the ctsthl command output does not match the correct identity in the ctsvhbal command output on either the Partition Load Manager server machine or the logical partition , change the HOST_IDENTITY value by completing the following steps:
  1. Remove the incorrect HOST_IDENTITY value by running the following command:
```
/usr/sbin/rsct/bin/ctsthl -d -n HOST_IDENTITY
```
  2. Add the correct HOST_IDENTITY value by running the following command:
```
/usr/sbin/rsct/bin/ctsthl -a -n IDENTITY -m METHOD \  -p ID_VALUE
```
    The value for the METHOD parameter can be obtained from the ctsthl command. Look for an entry for the machine itself. In that entry, use the value in the Identifier Generation Method field. One example is rsa512. For the ID_VALUE parameter value, use the Identifier Value field in the same entry.
To troubleshoot user or authorization type errors, check the ACL file on the logical partition. In the /var/ct/cfg/ctrmc.acls file, there is a stanza for IBM.LPAR towards the end of the file that looks similar to the following:
```
IBM.LPAR            plmuser@plmserver1.domain.com      *       rw  
```
The user name in the stanza must match the actual user name to run the Partition Load Manager. Also, the host name in the stanza must match what was returned by the ctsvhbal command which was run on the Partition Load Manager server machine. If the host name is incorrect, run the plmsetup script again, this time using the IDENTITY provided by the ctsvhbal command.
