Description of Fields

Table 102: Extended Board Statistics Data Structure

The Extended Statistics Data Structure returned from the Extended Board Statistics command contains these fields:

Total Commands Issued

This field reports the number of commands, SCSI Pass-through and Board- control, that have been processed by the adapter since power-up, reset, or the CLR bit option was used.

Number of SCSI Bad Status Conditions

This field reports the number of times a status other than Good was reported by all SCSI devices.

Number of SCSI Parity Errors

This field reports the total number of SCSI Parity Errors that have occurred since power-up, reset, or the CLR bit option was used.

Target Mode Selection Count

This field reports the number of times the RF3880 was selected as a target device.

Per SCSI Target — Number of Commands

This field is repeated for each of the 16 possible SCSI Target ID’s. It reports the number of commands received by that target since power-up, reset, or the CLR bit option was used. (The Number of Commands field for the SCSI ID that corresponds to the adapter ID will be zero, as will any ID in the table that is not presently used by a device.)
