NOTE Library SCSI-3 Command Set Mode Sense (6) Command (1AH) Test (Default set to 0) When this bit is set to 0, this indicates that the target shall not generate any false/test informational exception conditions. When this bit is set to one and Test Flag Number is set to 0, the target will generate a false informational exception condition based on the MRIE and Interval Timer fields. When the Test bit is set to one and the Test Flag Number is set to valid non-zero value, the target will generate/clear a test informational exception condition. The value of the Test bit returned by a Mode Sense command will remain at 0. The test action is based on the Test Flag Number value: 1 to 64 This will set in the Log page the TapeAlert flag indicated by the Test Flag Number. Once the TapeAlert flag is set, it is processed normally. -1 to -64 This will clear the TapeAlert flag indicated by the absolute value of the Test Flag Number. Clearing the flag in this way is equivalent to performing the specified corrective action for that flag. 32767 (0x7FFF) This will set in the Log page all of the TapeAlert flags that are supported by the target. Once the supported TapeAlert flags are set, they are processed normally. LogErr (Always set to 0) When this bit is set to 0, this indicates that the logging of informational exception conditions within a target is vendor specific. MRIE (Always set to 0x0) This field indicates the method used by the target to report informational exception conditions. This is standard SCSI terminology and is not related in any way to the "Information" severity level for the flags. 2- 34 Chapter 2
