Technical data

ipi(7D) Devices SunOS 5.5
The supported commands are:
IP_READ
IP_WRITE
Read or write data. The addressing is always by logical block
(ignoring [a-h] logical partition information); the Opcode modifier
is ignored.
IP_READ_DEFLIST
IP_WRITE_DEFLIST
Read or write one of the defect lists. The defect list is selected by
the Opcode modifier in bits <15:8> of the hdkc_cmd.
IP_FORMAT Format a range of cylinders. For this command, the block number
and sector count fields must both be a multiple of the number of
blocks per cylinder. The hdk_buflen field must be zero for this
command.
IP_REALLOC Reallocate a block. The controller attempts to recover the data
from the old block being reallocated. If the old data cannot be
recovered, a conditional success status is presented and a message
may be printed. The hdk_buflen field must be zero for this com-
mand.
DISK SUPPORT This driver handles all supported IPI drives by reading controller attributes and a label
from sector 0 of the drive which describes the disk geometry and partitioning.
