If a Version 2 Relationship is Suspended
Version 2 relationships may be suspended if a hardware or software failure occurs during a Version
2 operation. If Version 2 relationships are suspended, hosts may be unable to access the copy
target datasets.
To find whether suspended Version 2 relationships exist within the volumes, use the Pair Operation
window (see (page 74)). If the Relationship(S) column of the volume list displays S-Failed or T-Failed,
a suspended Version 2 relationship exists within the volume.
To delete a suspended Version 2 relationship, do one of the following:
• Delete the copy target dataset that has the suspended Version 2 relationship (that is, the dataset
that is inaccessible from the hosts). The operating system will automatically recognize the pair
that has the dataset to be deleted, and will issue the Withdraw command.
• Issue the TSO FCWITHDR command. If the suspended Version 2 relationship can be identified,
issue the FCWITHDR command to its extent.
If an ICKDSF Command Ended Abnormally
When you execute the ICKDSF command for Version 2 to a TrueCopy for Mainframe M-VOL or
ShadowImage for Mainframe S-VOL that is in pending status, ICKDSF job will end abnormally
with CC=12. (page 148) describes how to avoid the abnormal ending.
