5.2.11 Format Status log page (08h/00h)
5.2.11.1 Format Status log page overview
Using the format shown table 175, the Format Status log page reports information about the most recent successful format
operation and the state of the direct access block device since that operation was performed. The parameter codes for the
Format Status log page are listed in table 303.
The Format Status log page has the format defined in table 304.
DS bit, SPF bit, PAGE CODE field, SUBPAGE CODE field, and PAGE LENGTH field
The DS bit, SPF bit, PAGE CODE field, SUBPAGE CODE field, and PAGE LENGTH field are described in 5.2.2. The DS bit, the SPF bit, the PAGE CODE
field, and the SUBPAGE CODE field shall be set to the values shown in table 304 for the Format Status log page.
If a format operation has never been performed by the logical unit, then the log parameter for each Format Status log parameter
listed in table 303 is not defined by this standard. If a device server begins a format operation, then the device server shall set
each byte of the log parameter data (i.e., bytes four to n of the log parameter), if any, to FFh for each Format Status log parameter
(e.g., if the PARAMETER LENGTH field is set to 02h, then the log parameter data is set to FFFFh).
