STRIPE

Specifies that this is a STRIPE statement.

UNIT=unit

Specifies the device type or the device group name. The default is SYSALLDA.

VOLCNT=nnn

Specifies the maximum number of volumes in the range of 1 - 255. The value is used to allocate the following stripe data sets:

Stripe data sets that contain index records when the SORTFSZ control statement is specified
Stripe data sets that contain index records when duplicate key errors are detected

The default value is 10.

VOLCNT=1 is always used for the following stripe data sets:

Stripe data sets that contain WTO messages of each address space
Stripe data sets that contain SORT messages

Tip: You can override the default value in the runtime parameters module. See the explanation of the IIURDFLT STRIPE entry in Defining runtime parameters.
