How do you check the Dlpar is working or not?

The best way to monitor is by running the lspartition -dlpar command on the Management Console every few minutes and watch for the target LPAR to show up with a non-zero DCaps value.

How to enable RMC connection?

From the HMC GUI, click HMC Management → Change Network Settings → LAN Adapter/Details → Firewall Settings, and then select Allow RMC.

What is RMC connection?

RMC (Resource Monitoring and Control): RMC is a distributed framework and architecture that allows the HMC to communicate with a managed logical partition. An external network that the partition has access to and the HMC has acces to as well. For example, if HMC has a connection to a 9.

How do you use Dlpar in HMC 9?

Performing DLPAR Physical IO Moves with Enhanced HMC GUI

1. Remove the adapter from current partition. From the partition signon, Vary off the resource. Select Resources > All partitions.
2. Add the adapter to the target partition. Select the target partition. Select Physical I/O Adapters:

What does it mean when there is no output from DLPAR?

The output will show you any logical partitions which are ready for DLPAR operations. If there is no output at all, that means that either there are no LPARs which can communicate with HMC via network, or there is some problem with the HMC itself.

How to check DLPAR or dynamic logical partitioning problems?

You should check if DCaps value is higher than 0x0 and active value is higher than 0. If it is not, perform the next steps from the LPAR you are trying to perform DLPAR operations. Check the RMC connection to HMC using the following command: If you are using AIX 7.1 type the following command instead: You should see something like this:

How to check RMC connection to DLPAR operations?

You should check if DCaps value is higher than 0x0 and active value is higher than 0. If it is not, perform the next steps from the LPAR you are trying to perform DLPAR operations. Check the RMC connection to HMC using the following command:

What should be the connection between HMC and LPARs?

Since DLPAR function relies on RMC connection between HMC and LPARs, you should ensure that the public network interface of your HMC is properly configured and HMC can reach your LPARs via network (HMC connection to FSP (Flexisible Service Processor) of managed systems is not enough).
