Usage
MAXBURSTSIZE ASCII
Binary
0080h 2The value in this field specifies the
maximum amount of data to be
transferred without disconnecting. A
value of 0 sets no limit. This value is given
in 512 byte increments. For example, a
value of 8 indicates 4K bytes. Values that
are not multiples of 8 are rounded up to
the nearest multiple of 8. Minimum value
of this field is 0000h, maximum is FFFFh.
NODEFERRCVDERR ASCII
Binary
0 1 The drive reports deferred recovered error
as current recovered error (if set).
NODISCONFXDBLK ASCII
Binary
1 1 To turn on/off feature that prevents
disconnecting on every fixed block data
transfer
NORDYUAONUNLD ASCII
Binary
0 1 When set, Not Ready to Ready unit
attention will be removed from the unit
attention queue upon a successful
unload.
PERFMODE ASCII
Binary
1 1 When set, the drive is tuned for
performance.
When cleared, the drive is tuned for
capacity.
The default for 4 MB cache tape drives is
1 (performance mode). In performance
mode, compression is turned off to keep
the drive streaming, thus improving
performance. If PERFMODE is 0 on 4 MB
cache tape drives, then compression is
turned on, resulting in better capacity.
PERFMODE is ignored by 8 MB cache tape
drives.
