BLOCK (nnn) NOT MODIFIED: INVALID TTR ENCOUNTERED

Reason:

An invalid TTR was encountered while migrating a system catalog data set between unlike device types. The block is copied to the target volume without modification on the assumption that it is a disconnected catalog block. The block number indicated in the message is the actual sequential block number from the beginning of the catalog; that is, the first catalog block is indicated as block 1, not relative block. Check the validity of the copied SYSCTLG after a migration in which one or more erroneous blocks were identified by performing an automated comparison of IEHLIST SYSPRINT data sets for the source and target copies of the SYSCTLG.
