8.14.6 Removing the Resources Associated With the CPU Socket From the Control Domain
Use the ldm shrink-socket command to remove the resources in CPU socket #4 from a control domain.
The following example shows the removal of virtual CPUs and memory in CPU socket #4 from the control domain.
The following example shows the removal of virtual CPUs and memory in CPU socket #4 from the control domain.
# ldm shrink-socket cores=16 socket_id=4 primary # ldm shrink-socket memory=31488M socket_id=4 primary |
Note - The ldm shrink-socket command may fail to remove the target resource if the resource is busy. If so, stop the logical domain, and retry the ldm shrink-socket command. If the domain is the control domain, use delayed reconfiguration and try again. |
Use the ldm list-socket command to list the resources of each CPU socket. You can confirm that the memory in CPU socket#4 has been removed from the control domain.

Figure 8-4 shows the physical partition configuration after the ldm shrink-socket command is executed in the physical partition configured with two SPARC M10-4S units (BB#0 and BB#1).
