SCSI_WRITE
Specifies a frame of type SCSI Write with a bit pattern of
“12,0xFF,0x08;4,0xFF,0x06;40,0xFF,0x08,0x0A,0x2A;”.
SCSI_RW
Specifies a frame of type SCSI Write with a bit pattern of
“12,0xFF,0x08;4,0xFF,0x06;40,0xFF,0x08,0x28,0x0A,0x2A;”.
SCSI2_RESERVE
Specifies a frame of type SCSI-2 Reserve with a bit pattern of
“12,0xFF,0x08;4,0xFF,0x06;40,0xFF,0x16,0x56;”.
SCSI3_RESERVE
Specifies a frame of type SCSI-3 Reserve with a bit pattern of
“12,0xFF,0x08;4,0xFF,0x06;40,0xFF,0x5F;41,0xFF,0x01;”.
-pat bit_pattern
Specifies a unique combination of values in the first 64 bytes of a frame. The
syntax for the bit patterns is as follows: “offset, bitmask,value;[offset,
bitmask,value;] ...;” for example, "12,0xFF,0x08;4,0xFF,
0x06;40,0xFF,0x08,0x28;". This example monitors for SCSI read command
traffic transmitted from a port by filtering on offset 12 with a value of 0x08
(SCSI-FCP), on offset 4 with value 0x06 (unsolicited command), and on offset
40 with values of 0x08 or 0x28 (read command). Each pattern must end with
a semicolon (;) and the combined pattern must be enclosed in double
quotation marks. This operand is required with the --create option. It is
optional with the --change option.
The pattern components are as follows:
Offset
Specifies the offset within the frame. Offset 0 is the first byte of the
start-of-frame (SOF) delimiter, and offset 4 is the first byte of the frame
header. The offset must be in decimal format. Valid values for offset are
0, 4-63. Offset 0 is a special case that can be used to monitor the first
four bytes SOFx frames. The end-of--frame (EOF) delimiter cannot be
monitored. A maximum of six offsets can be specified for each filter, and
each offset can match up to four values. The count is incremented by
one, if a frame has a matching value in all the offsets specified by the
filter.
bitmask
Specifies the mask value to be applied to frame contents.
value
Specifies the values that need to be captured from the frame contents.
In SOFx frames the offset is specified as 0x0; value is specified as one of
the following. For example, the value of 0x6 matches frames of type
SOFi3:
