How to Modify the Amount of Kernel Zone Physical Memory

Ensure that you have enabled and configured the memory live zone reconfiguration feature.

See How to Enable Memory Live Zone Reconfiguration and Configuring Memory Live Zone Reconfiguration.
Change a kernel zone's physical memory size by specifying the new amount of physical memory as the value of the capped-memory:physical property.
1. Configure the kernel zone.
```
# zonecfg -z kz-name
```
2. Specify the value of the capped-memory:physical property.
  new-phys-memory-size is an integer with an optional scale unit (K for kilobytes, M for metabytes, G for gigabytes, and T for terabytes).
```
zonecfg:kz-name> set capped-memory:physical=new-phys-memory-size
```
3. (Optional) Configure the strict method by setting the capped-memory:memlzr property to the strict value.
```
zonecfg:kz-name> set capped-memory:memlzr=strict
```
4. Commit the change.
```
zonecfg:kz-name> commit
```
5. Exit zonecfg.
```
zonecfg:kz-name> exit
```
6. Apply the configuration changes to the running kernel zone.
```
# zoneadm -z kz-name apply
```
The following example commands set the capped-memory:physical property value to 32 Gbytes (32G) for the somekz kernel zone, commit the change, and apply the configuration changes to the running kernel zone:
```
zonecfg -z somekz
zonecfg:somekz> set capped-memory:physical=32G
zonecfg:somekz> commit
zonecfg:somekz> exit
# zoneadm -z somekz apply
```
