Verifying RMC connections for the mobile partition

You can verify the Resource Monitoring and Control (RMC) connection between the mobile partition and the Hardware Management Console (HMC). This RMC connection is required to perform active partition mobility.

You must be a super administrator to complete this task.

RMC is a no-charge feature of the AIX® operating system that can be configured to monitor resources and perform an action in response to a defined condition. With RMC, you can configure response actions or scripts that manage general system conditions with little or no involvement from the system administrator. On the HMC, RMC is used as the main communication channel between AIX and Linux logical partitions and the HMC.

To verify an RMC connection for the mobile partition, complete the following steps:

  1. Using the HMC command line, enter lspartition -dlpar.
    Your command results will look similar to this example:
    ze25b:/var/ct/IW/log/mc/IBM.LparCmdRM # lspartition -dlpar
<#0> Partition:<5*8203-E4A*1000xx, servername1.austin.ibm.com, x.x.xxx.xx>
Active:<0>, OS:< , , >, DCaps:<0x2f>, CmdCaps:<0x0b, 0x0b>, PinnedMem:<0>
<#1> Partition:<4*8203-E4A*10006xx, servername2.austin.ibm.com, x.x.xxx.xx>
Active:<0>, OS:<AIX>, DCaps:<0x2f>, CmdCaps:<0x0b, 0x0b>, PinnedMem:<0>
<#2> Partition:<3*8203-E4A*10006xx, servername3.austin.ibm.com, x.x.xxx.xx>
Active:<1>, OS:<AIX>, DCaps:<0x2f>, CmdCaps:<0x0b, 0x0b>, PinnedMem:<340>
<#4> Partition:<5*8203-E4A*10006xx, servername4.austin.ibm.com, x.x.xxx.xx>
Active:<1>, OS:<AIX>, DCaps:<0x2f>, CmdCaps:<0x0b, 0x0b>, PinnedMem:<140>
</AIX></AIX></AIX>
    • If the results for your logical partition are <Active 1>, then the RMC connection is established. Skip the rest of this procedure and return to Preparing the mobile partition for partition mobility.
    • If the results for your logical partition are <Active 0> or your logical partition is not displayed in the command results, continue to the next step.
  2. Verify that the RMC firewall port on the HMC is disabled.
    • If the RMC firewall port is disabled, skip to step 3.
    • If the RMC firewall port is enabled, change your HMC firewall setting. Repeat step 1.
  3. Use telnet to access the logical partition. If you cannot use telnet, open a virtual terminal on the HMC to set up the network on the logical partition.
  4. If the logical partition network has been set up correctly and there is still no RMC connection, verify that the RSCT fileset is installed.
    • If the RSCT fileset is installed, use telnet to the HMC from the logical partition to verify if the network is working correctly and that the firewall has been disabled. After verifying these tasks, repeat step 1. If you continue to have problems establishing an RMC connection for your mobile partition, contact your next level of support.
    • If the RSCT fileset is not installed, use your AIX installation CD to install the fileset.
Important: It takes approximately five minutes for RMC connection to establish the connection after the network setup has been changed or after activating the logical partition.
