4.1 Control/Sense Commands

a.Page code

This field identifies which log page is being transferred.

The log pages that can be transferred by this command are shown in Table 4.21.

Table 4.21 Page code

Page Code	Description	Changeable Parameter

01	Buffer Overrun/Underrun Page	Disable
02	Write Error Counter Page	Enable
03	Read Error Counter Page	Enable
05	Verify Error Counter Page	Enable
06	Non-medium Error Page	Enable
0D	Temperature Page	Disable
0E	Start-stop Cycle Counter Page	Enable only 0002
0F	Application Client Log Page	Enable
10	Self-Test Result Log Page	Disable
15	Background Medium Scan Page	Disable
18	Protocol Specific Port Log Page	Disable

b. Page length

This field specifies the length in bytes of the following log parameters. If the application client sends a page length that results in the truncation of any parameter, the device server terminates the command with CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]).

The log pages contain one or more special data structures called log parameters as shown below. Each log parameter begins with a 4-byte parameter header followed by one or more bytes of "Parameter Value" data.
