Board Information (15H)

Per Target - Disconnect Time-out

If Disconnects are enabled for the target with the General Options command, this field represents the amount of time the adapter will wait for a reconnect before taking error recovery action. For more information, refer to the section of this chapter that explains the General Options, Unit Options, and Extended Unit Options commands.

Per Target - Retry Limit

This field specifies the maximum number of retries the RF3880 will attempt before reporting an error. This value is set for each target with the Unit Options or Extended Unit Options command.

Per Target - Sense Count

This field reports the number of Sense bytes that the adapter will return for this target. This number is defined by the Unit Options or Extended Unit Options commands.

Per Target - Device Flags

The Device Flags field is a word wide. It reports the options that you have selected for this target with the Unit Options or Extended Unit Options command. The format is as shown below:

BITS

15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0

0	SS	0	RBE	RCE	RPE	ISB	INT	0	TQE	0	0	WID	IAT	SYN	UNQ

Table 99: Bit-meanings of Device Flags Field

UNQ Untagged Queuing - This bit indicates whether the RF3880 will queue commands to a target with multiple LUN’s.

0 ⇒ One command at a time will be sent to this target.

1 ⇒ Commands to this target will be queued; it has multiple LUN’s.

SYN Synchronous Negotiation - This bit indicates whether negotiations for synchronous transfers will be initiated for this target.

0	⇒ Synchronous transfer negotiation will not be initiated by adapter.
1	⇒ Adapter will initiate synchronous transfer negotiations.

IAT Inhibit ATN Signal - This bit indicates if the adapter is to assert the ATN signal.

0 ⇒ Adapter will assert ATN for this target.

1 ⇒ Adapter will not assert ATN for this target.

WID Wide Transfers - This bit indicates whether negotiations for wide data transfers will be initiated for this target.

0 ⇒ Wide data transfer negotiations will not be initiated by the adapter.

1 ⇒ Adapter will initiate wide data transfer negotiations.
