RECtech
optionally, specifies the method used to record data tracks on the tape surface for the
desired data set. You can enter a list of recording techniques, but they must be
separated by commas.
Notes:
1. A list specifies a generic pool from which a selection is made. There is no
implied priority.
2. The SL8500 library supports only the T9 x 40 (9840/T9840B/T9840C and
T9940A/T9940B) media types and recording techniques.
RECtech and MODel are mutually exclusive.
If this parameter is not specified on any matching TAPEREQ, a default is chosen
based on the value of the MEDia parameter on the first matching TAPEREQ. Table 6
shows default values used if RECtech is omitted.
To avoid problems, StorageTek recommends that all TAPEREQ statements specify
MEDia and RECtech consistently. Make sure to include either one or both parameters on
each statement.
If both media type and recording technique are omitted, all available devices are eligible
for allocation.
Valid recording techniques are:
LONGItud
indicates any device that uses longitudinal recording.
18track
indicates a 4480 transport.
36track
indicates a 4490, 9490, or 9490EE transport (any device that records in 36-track
mode).
