Our server development has confirmed with our design, it is possible that the remote volhist entry can be different. Development believe this is their design. However, the existing document did not document this clearly. They agreed to open a Doc. APAR to properly document this for command query volhist.
In other words they felt that no action was needed other than to document that this possible occurrence within the TSM Admin and Reference guides. So I asked it be escalated since it is definitely a flaw and finally heard back from support and was told the following:
They agree what you observed or reported in this case is incorrect even though it does not cause any function lose. They have agreed to take the APAR IC65048 as a defect ( instead of Document ). However, this APAR would take a big code change to "fix" this issue and after first evaluate, they will not be able to deliver a fix in the service stream. They request to open a DCR ( design change record ) so development can make this change on a release boundary so that there is sufficient testing for a code change.So it looks like IBM will eventually fix this. Thanks to IBM support for helping me get development to at least go beyond the Doc. APAR.
