INZTAP aborts on CHECK(*YES)

[rob@xxxxxxxxx]

We initialize the tapes in our backup.  I realize that there has been some 
discussion on this, but otherwise...

I have a backup module which does a CHKTAP followed by an INZTAP.  The 
CHKTAP retrieves the volume ID and that is used during the INZTAP.  Often 
the INZTAP will fail with a media error (CPF5349).  We clean the drive 
immediately before the backup.

We wondered if it was because the INZTAP is so soon after the CHKTAP.  But 
that is not it.  The tape can sit in the drive all night long.  In the 
morning if we do a INZTAP with CHECK(*YES) we'll still get the media 
error.  However if we change the INZTAP to CHECK(*NO) we do not get the 
media error.

The CHKTAP was able to successfully retrieve the volume id, therefore I 
assume it CAN read the tape.

Perhaps next time I should do a DSPTAP prior to the INZTAP to see if it 
will pass that.
