The Cluster Edition includes the instance parameter for disk init:
disk init
name = “device_name”
physname = “physical_name”,
[vdevno = virtual_device_number ,]
size = number_of_blocks
[, vstart = virtual_address
, cntrltype = controller_number ]
[, contiguous]
[, dsync = {true | false}]
[ ,directio = [{true | false}]
[, instance = “instance_name”]
The instance parameter marks the device as private and sets its owning instance to instance_name.
By default, the disk init . . . directio parameter is set to false for non-clustered versions of Adaptive Server.
For the Cluster Edition, the default behavior of the disk init . . . directio parameter is set to true.
The Cluster Edition provides a new option in the disk init command to create a private device:
[instance = "instance_name"]
For more information on disk init, see “Using Temporary Databases”.
The directio parameter is ignored
if you use raw devices.
