Field definitions (listed alphabetically)
Action Code
06h
Port Parameters.
Drive Capabilities
This is a bit-significant field that indicates which device control codes defined by SFF 8045 are supported by the drive. The
corresponding device control code is supported. For example, a one in bits 7 and 6 indicates that device control codes 7
and 6 are supported. This indicates the drive supports Fibre Channel link rates or 1 and 2 GHz.
ESI Page
00h
Identifies the ESI page code used (00h).
LSP CHG (Link Status Page Change)
This bit-significant field indicates which device control codes defined in SFF 8045 are supported by the drive.
0
The Link Status Page data has not changed.
1
The date in the Link Status Page has changed since the enclosure last read the Link Status Page.
Port Bypass
0
The drive is not requesting bypass.
1
The drive is asserting the –ENBL BYP CH signal in the SCA connector for the port.
Port Link Fail
0
The drive is not currently detecting a loop failure condition as defined in FC-AL for the port.
1
The drive is currently detecting a loop failure condition as defined in FC-AL for the port.
Port Link Rate
This field contains the value defined for the Fibre Channel link rate by the Device Control Code inputs in SFF 8045. For
example, seven represents 1 GHz.
