The OAM optical device statements in the IOCP/MVSCP input data
set must be upgraded for a migration to HCD/IODF for the following
reasons:
- In contrast to IOCP, HCD validates device and control unit types,
and associated parameters such as the protocols for a given control
unit type and the connection of a device to a control unit.
- HCD introduced the specification of the SDA model for the 3995.
- HCD uses the true 3995 device type that had to be defined as a
“look-like” device for MVSCP (3995 was defined as a “look-like”
CTC, CTCS, or 3088 in MVSCP).
There are really two options that can be used to assist you in
migrating to the HCD/IODF structure. The first method, and the preferred
option, is to redefine your optical devices using HCD control unit
and device definition panels. An alternate method is to change your
MVSCP/IOCP statements and migrate them to IODF. Both methods are discussed
in this section.
The preferred method of migrating your
configuration from IOCDS to IODF is to perform the following steps:
- Delete the CNTLUNIT and IODEVICE statements for the OAM 3995 optical
devices from the old IOCP/MVSCP input data set.
- Use the HCD migration panels or run a batch job to create a migrated
IODF work file using the updated IOCP/MVSCP input from the previous
step. This will create an IODF work file that does not include OAM
3995 optical devices.
- Add the OAM 3995 optical devices to the IODF work file generated
from the previous step by using the appropriate HCD panels. Use the
HCD Control Unit Panel to add the OAM 3995 optical library controllers.
Use the HCD I/O Device Panel to add the OAM 3995 optical devices.
An alternate method of migrating from MVSCP/IOCP to IODF is to
change the device statements within the IOCP input data set. The HCD
panels or a batch job can then be used to perform the migration.
Note: It is recommended that the preferred method
be used instead of this alternate method. The changes made to the
device and control unit statements in the alternate method are device
specific and therefore might cause errors if not modified correctly.
The following examples are provided to assist you in changing your
MVSCP/IOCP statements for 3995 optical devices for migration purposes
only. These examples can be used when migrating an old MVSCP/IOCP
input data set into an IODF file using the HCD migration panel or
batch job. These statements should not be used as an input example
for MVSCP or IOCP programs.
Here are some examples of changing the device and control unit
statements for 3995-C xx optical devices:
