Table 4-5. S.FT3 Bit Description
BIT VALUE DESCRIPTION
0-7 1 Reserved
Table 4-6. S.FT4 Bit Description
BIT VALUE DESCRIPTION
0-2 Reserved
3 1 Support ANSI SCSI-3 Write Buffer modes 6 and 7. Reference the Write Buffer com-
mand description in the M2488 for a description of Write Buffer modes 6 and 7.
0 Write Buffer modes 6 and 7 are reserved (per ANSI SCSI-2).
4 1 For SCSI commands which require access to tape or the data buffer, Busy status is not
generated when the command is received for an ITL nexus which is currently processing
previously issued immediate SCSI command. The new SCSI command is held (following
a disconnect, if allowed) , then processed after the current immediate operation under
way has completed.
NOTES:
1) This feature is similar to FT4, bit 5 defined below, except for sense key 2 (Not Ready)
with ASC/ASCQ 0401 (LUN is in process of becoming ready) not being generated.
2) If FT4, bit 4 and FT4, bit 5 are both set, then the FT4, bit 4 feature takes precedence.
0 Busy status is generated when a SCSI command, which requires access to tape or data
buffer, is received for an ITL nexus currently processing a previously issued immediate
SCSI command.
