Execution States

To control the execution state of SMF processes, you use two PUP commands: UP

and DOWN. A process in the UP execution state is fully operational. A process in the

DOWN execution state is capable of supporting only informational operations. Other

PUP commands, which you use to define and manage storage pools and virtual disks

and manage SMF processes, require that a process be in the UP or DOWN execution

state or in other states. For more information about various process states see

Controlling Process States on page B-24.

Several other commands can be used to manage SMF processes:

Defining Storage Pools and Virtual Disks

To define storage pools and virtual disks, $ZSMS must be running so it can update its

POOLTBL and VDPTBL catalog files.

Storage Pool Configuration

To configure a storage pool, use the PUP DEFINEPOOL command to name the

storage pool and define its configuration attributes:

DEFINEPOOL $MYPOOL [attributes]

The name, $MYPOOL, in this example, must be the same as that for a process

configured or to be configured as a storage pool process in OSCONFIG using COUP.

The attributes describe such storage pool characteristics as physical catalog location

and characteristics of volumes in the pool.

To modify the attributes of a storage pool, use the PUP REDEFINEPOOL command.

To delete a storage pool configuration, use the PUP DELETEPOOL command to

delete information about the storage pool from the $ZSMS catalog and the COUP

DELETE command to delete the OSCONFIG entry for the corresponding process.

PUP PRIMARY Changes the processor in which a process is executing to its

backup processor and makes the current primary processor the

new backup processor (takes effect immediately)

COUP ALTER Changes the attribute values of a process in its OSCONFIG

entry (does not take effect until the process is restarted)

COUP DELETE Deletes an OSCONFIG entry for a process that has been

stopped (does not take effect until the process is restarted)
