Parameter Data Formats

d.SIZE (size enable) (not supported)

"1" : Divides the data buffer in accordance with the value specified for the cache segment size (bytes 14, 15).

"0" : Divides the data buffer in accordance with the value specified for the number of cache segments (byte 13).

This bit cannot be changed. The IDD disregards the specification in this bit and operates according to the "Default" value (= "0").

e.DISC (discontinuity)

"1" : Even if a track switch occurs during Look-Ahead, the Look-Ahead operation continues without interruption.

"0" : Look-Ahead is terminated at the point where track switch occurs during Look-Ahead.

This bit cannot be changed. The IDD disregards the specification in this bit and operates according to the "Default" value (= "1").

f.IC (initiator control enable)

"1" : Dividing of cache segments is according to the SIZE bit specification.

"0" : Dividing of the cache segments is performed by an algorithm that is inherent in the IDD.

The IDD disregards this bit and operates according to the default value (= "0").

g.Demand Read Retention Priority (not supported)

This field advises the device server the retention priority to assign for data read into the cache that has also been transferred from the logical unit to the application client.

The IDD are not supported this field. Thus, the IDD disregards the specification in this field.

"F" : Data put into the cache via a READ command was not replaced if there is other data in the cache that was placed into the cache by other means and it may be replaced.

"1" : Data put into the cache via a READ command was replaced sooner than data placed into the cache by other means.

"0" : Indicates the device server was not distinguish between retaining the indicated data and data placed into the cache memory by other means.

h.Write Retention Priority (not supported)

This field advises the device server the retention priority to assign for data written into the cache that has also been transferred from the cache memory to the medium.
