TAPEDRIVES Scheduler Attribute
The TAPEDRIVES scheduler attribute specifies the number of tape drives available for
use by jobs.
number
is a number in the range 0 through 99 specifying the number of tape drives
available.
Considerations
•
A scheduler adopts the attribute TAPEDRIVES 2 by default when cold
started.
Note. The scheduler cannot determine the actual number of tape drives configured for its
node. Consequently, you must check tape drive availability before specifying the TAPEDRIVES
scheduler attribute. (Use the TAPECOM STATUS command or the PUP LISTDEV TYPE 4
command, or their equivalent MEDIACOM and SCF commands, respectively.)
