Value Description
00b Current threshold values
01b Current cumulative values
10b Default threshold values
11b Default cumulative values
The "PC" bits are ignored by the drive. The drive assumes that current cumulative parameters are
selected.
The "Parameter List Length" field specifies the length in bytes of the parameter list that is located in
the Data-Out Buffer. If a parameter list length results in the truncation of any log parameter, the
device server terminates this command with CHECK CONDITION status (ILLEGAL REQUEST
[=5] / Invalid field in CDB [=24-00]).
A "Parameter List Length" of zero indicates that no pages shall be transferred. This condition shall
not be considered an error.
Note:
The IDD does not support that the application client should send pages in ascending order by
page code value if the Data-Out Buffer contains multiple pages.
