Working with z/VM recording devices

Typical tasks that you perform with z/VM recording devices include starting and stopping record collection, purging records, and opening and closing devices.

Starting and stopping record collection
By default, record collection for a particular z/VM recording service begins when the corresponding device is opened and stops when the device is closed.
Purging existing records
By default, existing records for a particular z/VM recording service are purged automatically when the corresponding device is opened or closed.
Querying the z/VM recording status
Use the recording_status attribute to query the z/VM recording status.
Opening and closing devices
You can open, read, and release the device. You cannot open the device multiple times. Each time the device is opened it must be released before it can be opened again.
