[5] IP
An initialization pattern (IP) bit of one indicates that an initialization pattern descrip-
tor is included in the FORMAT UNIT parameter list immediately following the defect
list header. An IP bit of zero indicates that an initialization pattern descriptor is not
included and that the target uses its default initialization pattern.
The initialization pattern type field indicates the type of pattern the target shall use to
initialize each logical block within the initiator accessible portion of the medium (Table
5.2.1-6c). All bytes within a logical block shall be written with the initialization pat-
tern. The initialization pattern is modified by the IP modifier field as described above
in Table 5.2.1-6b.
[6] DISABLE
A disable saving parameters (DSP) bit of one, specifies that the target shall not
SAVING
save the MODE SELECT savable parameters to non-volatile memory during the
PARAMETERS
format operation. A DSP bit of zero specifies that the target shall save all the MODE
SELECT savable parameters for all initiators to non-volatile memory during the for-
mat operation.
[7] IMMEDIATE
An immediate (IMMED) bit of zero indicates that status shall be returned after the
first operation has completed. An Immed bit value of one indicates that the target
shall return status as soon as the command descriptor block has been validated,
and the entire defect list has been transferred. Check individual drive Product manual
Vol. 1 section 11.4 for applicability of this feature.
[8] VS
Vendor Specific. Not used.
[9] DEFECT
The length of any following D list (Defect Descriptors) must be equal to 8 times
LIST
the number of sectors to be reallocated per Table 5.2.1-6e or Table 5.2.1-6f.
LENGTH
Note.
The initiator may not use any previously defined “C”, “G”, or “D” lists if the sector size (block length)
has been changed.
The initialization pattern option specifies that the logical blocks contain the specified initialization pattern. The
initialization pattern descriptor (Table 5.2.1-6a) is sent to the target as part of the FORMAT UNIT parameter
list.
