Target Selection Data Structure	Page 6 - 11

Flags Field

This field contains flags that report the status of the selection process. The format of this field is as follows:

BITS

7	6	5	4	3	2	1	0

CC	ERR	RTY	0	0	0	0	TME

Table 45: Meaning of Flags Field

TME Target Mode Enabled - This bit indicates the current status of Target Mode.

0 ⇒ Target Mode has been terminated. This Target Selection Data Structure was not due to an initiator selecting the adapter. (Either Target Mode was disabled by a SCSI Reset, or by the Target Mode Disable command.)

1 ⇒ Target Mode is enabled. This Target Selection Data Structure was sent due to an initiator selecting the adapter.

RTY Retry - Indicates whether a selection process required retries to complete.

0 ⇒ No retries were required.

1 ⇒ Retries were required to complete.

ERR Error Status - Identifies when a selection process completes with an error. Used in conjunction with the Error field, indicates if error was recoverable.

0 ⇒ No error occurred, or if non-zero value exists in the Error field, error was recoverable.

1 ⇒ An error occurred. Also set if Target Mode was terminated due to a SCSI Reset.

CCCommand Complete - Indicates whether a selection process has finished.

0 ⇒ Command not complete.

1 ⇒ Command complete.

Error

When the adapter detects an error, this byte contains an error code to describe the condition. There are special Target Mode error codes that indicate Target Mode error conditions. These codes are listed along with the other adapter error codes in Appendix A.
