Mode Sense: SAS Disconnect/Reconnect Page Definitions:
PS The parameters Saveable bit is set to 0.
SPF The library returns a value of:
0 = SubPage Format bit, indicating page_0 format is being used.
Page Code This field is set to:
02h = identifies the page as the Disconnect/Reconnect page.
Bus Inactivity
Time Limit
This field contains the maximum time in 100 µs increments that an SSP
target port is permitted to maintain a connection without transferring a frame
to the SSP initiator port.
n 0000h indicates that there is no bus inactivity limit.
Maximum Connect Time
Limit
This field contains the maximum duration of a connection in 100 µs
increments.
n 0000h specifies that there is no maximum connection time limit.
Maximum Burst Size For read data, this field contains the maximum amount of data in 512-byte
increments that is transferred during a connection by an SSP target port per
I_T_L_Q nexus without transferring at least one frame for a different I_T_L_Q
nexus.
For write data, the value shall specify the maximum amount of data that an
SSP target port requests via a single XFER_RDY frame.
n 0000h in this field specifies that there is no maximum burst size.
First Burst Size If the ENABLE FIRST BURST bit in the COMMAND frame is set to zero, then
the FIRST BURST SIZE field is ignored.
If the ENABLE FIRST BURST bit in the COMMAND frame is set to one, then
the value in the FIRST BURST SIZE field contains the maximum amount of
write data in 512-byte increments that may be sent by the SSP initiator port to
the SSP target port without having to receive an XFER_RDY frame from the
SSP target port.
