Do you see messages like this in the SYSLOG?

 CBR3006I Library $ATL0002 with Library ID A0420 unknown in I/O
 configuration.
*CBR3002E Library $ATL0002 no longer usable.
 CBR3006I Library $VTS0002 with Library ID B1589 unknown in I/O
 configuration.
*CBR3002E Library $VTS0002 no longer usable.


If so, that means that the Library IDs in the IODF / SMS do not match the
physical Library IDs at DR. You need to change the IODF and SMS to have the
proper physical Library IDs. This is one area which z/VM cannot virtualize.
If you don't know the actual Library IDs, the simplest way to get it is to
enter a command like I did below. Note that 0600 is a virtual tape address,
and 0800 is an ATL address.

V 0600,ONLINE
IEE103I UNIT 0600 NOT BROUGHT ONLINE 635
IEE763I NAME= IECTDSR2 CODE= 0000000800000000
IEA437I TAPE LIBRARY DEVICE(0600), HCD(B1589-01),DEVICE(70868-01)
IEE764I END OF IEE103I    RELATED MESSAGES

V 808,ONLINE
IEE103I UNIT 0808 NOT BROUGHT ONLINE 578
IEE763I NAME= IECTDSR2 CODE= 0000000800000000
IEA437I TAPE LIBRARY DEVICE(0808), HCD(A0420-01),DEVICE(17909-02)
IEE764I END OF IEE103I    RELATED MESSAGES


The above shows that my HCD has B1589-01, but the physical device has
70868. So I went into the HCD and changed the Library ID for the devices. I
also updated SMS for the VTS definition. I had to do the same with the
physical ATL devices. I could then do a soft activate of the new IODF and
an ACTIVATE of the new (updated) SCDS as well.
