IEF022I

Explanation
The allocation request failed because the system
programmer marked the required tape device as unavailable to allocation
by the VARY xxxx,UNAVAILABLE command.
If a VARY ONLINE or VARY
AVAILABLE command was done while the job was in allocation, any new
devices made available by the command are not available to the job,
because jobs in the recovery allocation are still locked onto the
eligible device table (EDT) as existed at the start of device allocation
processing. The newly available device becomes available only after
the job ends, or is cancelled, and then is submitted again.
In
the message text: jobname
The name of the job.
procstep
The name of the step in the procedure.
stepname
The name of the job step.
ddname
The name of the DD statement.
+ xxx
The relative position of a data set within a concatenation of
data sets, including all data sets implicitly concatenated (through
GDG ALL or OPTCD=B requests). See z/OS MVS JCL User's Guide for
more information about GDG ALL or OPTCD=B requests when used within
a set of concatenated data sets. The first data set of a concatenation
would be +000, but the value +000 is never shown.

System action
System processing continues.

Operator response
None

System programmer response
None

Problem determination
Use the display units command (D U,,,devnum,1)
to determine the status of the device as coded in the JCL or dynamic
allocation request. If the JCL or dynamic allocation request cannot
be updated to request a different device number, use the VARY ONLINE
or VARY AVAILABLE commands to change the device status and make it
available for allocation. Use the D U,TAPE,UNAVAIL command to show
all offline, unavailable tape devices and determine a different device.
