TrueCopy for z/OS user guide 129
• Data: M-VOL is fenced when the MCU cannot successfully execute an update copy operation for
any reason.
• Status: M-VOL is fenced only if the MCU cannot change the R-VOL status to suspended when an
update copy operation fails.
• CFW Data: Specifies whether the CFW data is copied to the R-VOL. For TCPD-MF, only Copy to R-VOL
is available.
• Asynchronous Parameters (Async only):
• Error Level: Error level for the new pair(s): Group, or Volume.
NOTE: To set the parameters on multiple volumes at once without changing individual parameters
per volume, make the box for the parameters you do not want to change blank. Only parameters
you input are changed.
• Cancel: Cancels settings you made and closes the Change Pair Option panel.
• Set: Sets parameters and closes the Change Pair Option panel.
To change the pair options for one or more TC390 volume pairs:
1. Connect to the MCU of the pair(s) to be changed the options and start the TC390 software.
2. From the CU Number tree on the TrueCopy main window, select the CU number of the correct CU
image.
3. From the Volume list on the TrueCopy main window, select the TC390 volume pair(s) that you want to
modify the options. Select either TC390 Sync or Async pairs, but not both.
4. Right-click to display the pop-up menu and click Change Pair Option. The Change Pair Option window
is displayed.
5. From the Change Pair Option window, select the pair options for the selected pair(s), and click Set to
close the Change Pair Option window and set the parameters. The list changes to the Pair Settings
Parameter list (Change Pair Option). Repeat this step as needed to change the pair options for the
pair(s).
NOTE: The options can be modified and/or canceled after you have set them. See ” Modifying
Parameters and Omitting Selected Volumes ” on page 111.
6. If you want to execute the pair option change requests quickly, select the Use Time-Saving Model check
box above the Pair Settings Parameter list (Change Pair Option).
7. Click Apply on the TrueCopy main window to change the options for the specified pair(s).
8. From the TrueCopy main window, verify that the pair option change was completed successfully.
ICKDSF Considerations for TrueCopy Volumes
The XP128/XP1024/XP10000/XP12000 supports the use of the ICKDSF utility program. ICKDSF
performs functions for the installation, use, and maintenance of DASD as well as service functions, error
detection, and media maintenance.
ICKDSF on a TrueCopy M-VOL
ICKDSF activities involve write I/O operations with device support authorization instead of normal
authorization. Because the MCU does not duplicate write I/O operations with device support authorization
at the R-VOL of a TC390 volume pair, you must suspend a TC390 pair before running ICKDSF on a TC390
M-VOL.
To perform ICKDSF on a TC390 M-VOL:
1. Connect to the MCU of the volume pair, and then start the TC390 software.
2. Suspend the volume pair, if not already suspended, using the R-VOL suspend option and the TC390A
Volume and Purge suspend options (see ” Suspending TrueCopy Pairs (Suspend Pair) ” on page 120).
You can also use the CSUSPEND TSO command to suspend the pair.
