Disabling BSR arrays for the mobile partition

You can disable barrier synchronization register (BSR) arrays for the mobile partition by using the Hardware Management Console (HMC) so that you can perform active partition mobility.

1. In the navigation pane, select Systems Management and select Servers.
2. In the navigation pane, select the managed server of your choice and select Properties.
3. Click the Capabilities tab.
   • If Barrier Synchronization Register (BSR) Capable is True, click OK and continue with the next step.
   • If Barrier Synchronization Register (BSR) Capable is False, the server does not support BSR. Skip the rest of this procedure and continue to HMC-managed systems: Preparing the mobile partition for partition mobility.

     The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.

     When the HMC is at version 8.7.0, or later, complete the following steps to disable BSR for the mobile partition:

     1. In the navigation pane, click the Resources icon .
     2. Click All Systems. The All Systems page is displayed.
     3. In the work pane, select the system and click Actions > View System Properties. The Properties page is displayed.
     4. Click Licensed Capabilities. The Licensed Capabilities page lists the features that are supported by the server.
     5. In the Licensed Capabilities page, verify the list of features displayed.
        • If Barrier Synchronization Register (BSR) Capable is marked by the icon, click OK and continue with the next step.
        • If Barrier Synchronization Register (BSR) Capable is marked by the icon, the server does not support BSR. Skip the rest of this procedure and continue to HMC-managed systems: Preparing the mobile partition for partition mobility.
4. In the navigation pane, open Systems Management and select Servers.
5. Select the managed server of your choice in the navigation pane.
6. In the work pane, select the logical partition of your choice, click the Tasks button, and select Properties.
7. Click the Hardware tab.
8. Click the Memory tab.
   When the HMC is at version 8.7.0, or later, complete the following steps to view the memory details of the mobile partition:

   1. In the navigation pane, click the Resources icon .
   2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition. Click View System Partitions. The All Partitions page is displayed.
   3. In the work pane, select the logical partition and click Actions > View Partition Properties.
   4. Click the Memory tab.
   • If the number of BSR arrays equals zero, the mobile partition can participate in active or inactive partition mobility. Skip the rest of this procedure and continue to HMC-managed systems: Preparing the mobile partition for partition mobility.
   • If the number of BSR arrays is not equal to zero, then take one of the following actions:
     • Perform an inactive migration instead of an active migration.
     • Click OK and continue to the next step to prepare the mobile partition for an active migration.
9. Select the mobile partition, and then select Configuration > Manage Profiles.
   When the HMC is at version 8.7.0, or later, complete the following steps to view the Manage Profiles page:

   1. In the navigation pane, click the Resources icon .
   2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition. Click View System Partitions. The All Partitions page is displayed.
   3. In the work pane, select the logical partition and click Actions > Profiles > Manage Profiles.
10. Select the partition profile with which you will reactivate the mobile partition, and select Action > Edit.
11. Click the Memory tab.
    • If the number of BSR arrays equals 0, the mobile partition can participate in active or inactive partition mobility. Skip the rest of this procedure and continue to HMC-managed systems: Preparing the mobile partition for partition mobility.
    • If the number of BSR arrays is not equal to 0, then take the following action to change BSR to 0 if you want to do an active migration:
      • Enter 0 in the field for the BSR arrays.
      • Click OK and continue to the next step to prepare the mobile partition for an active migration.
