Seagate Fibre Channel Interface - Manual (Page 237)

Fibre Channel Interface Manual, Rev. D 223
12.13.4 Format Parameters page (03h)
The Format Parameters page implementation is defined in Table 149. This table summarizes the function and
defines the default values for each bit. See the individual drive’s Product Manual, Volume 1, Mode Sense Data
section for changeable values.
The only time this page of parameters may be sent is immediately before sending a Format Unit command to
the disc drive. The current parameters for this page are updated immediately but any changes between these
current parameters and the existing media format are not in effect until after the Format Unit command is com-
pleted.
The actual implementation of reserving spare areas for defect management takes place during the Format Unit
command.
Note. In Table 149, zone refers to defect management zone (one or more tracks), not a ZBR (variable
track capacity recording) zone. ZBR zones are referred to as notches (page 0Ch is the Notch
page).
