A page set that was originally page set n is being presented as being a different page set, probably because the started task JCL procedure for the queue manager has been changed. Register 0 contains the identifier of the page set in error, and register 2 contains the identifier it was previously associated with.

If the problem persists, or no changes have been made to these statements, collect the items listed in Data manager problem determination and contact your IBM support center.
Your data set is not recognized as an MQ page set. This is probably because it has not been formatted.
Register 0 contains the identifier of the page set in error.

This reason code is caused by one of the following:
Neither of these actions is allowed.
Register 0 contains the identifier of the page set in error.

An internal error has occurred during processing of an MQGET call with the Mark Skip Backout option.
The current execution unit terminates with completion code X'5C6', and a dump is produced.
Collect the items listed in Data manager problem determination and contact your IBM support center.
During restart, the queue manager detected that a page set has been truncated. This is probably because the data set allocated during restoration of a backup was smaller than required to hold the backed up data, and so the data has been truncated. It may also occur if page set 0 is larger than the maximum supported page set size.
The identifier of the page set in error is put in register 0. Restart is terminated.
Reallocate the data set correctly, restore the backed up data if necessary, and restart the queue manager.

During restart, the data manager found a queue whose messages are apparently located in a newly added page set. This is probably because the queue manager was run with a page set offline, and a new page set was formatted to replace the original one. This will lead to data loss.

MQ was extending a page set at startup, based on log records from earlier dynamic page set extend operations. (MQ does this so that any media recovery operation will have the required number of pages available in the page set.)
The page set could not be extended to the required RBA value.
The contents of the relevant registers are as follows:

Create a larger page set, using multiple disk volumes if required, with a larger secondary extent value. The high page number of the page set should at least match that shown in register 2 in the dump.

An attempt to restart with a log from another queue manager was detected. The queue-sharing group name recorded in the log during checkpoint does not match the name of the queue-sharing group in the queue manager using that log. If the correct log is being used, you can perform the change only after a clean shutdown of the queue manager, that is, after a quiesce.
Message CSQI060E is issued before this error occurs.
Restart is terminated abnormally with completion code X'5C6' and a dump is produced.
