It looks to me as if the HSMs themselves are negatively impacting each other, the only data set on the voilume being the OCDS with it's VVDS, VTOCINDEX VTOC. I worked on a similar problem once where HSM on system B owned the reserve and our vendor product on system A couldn't do an I/O - got Start Pending. User had no product installed to convert Reserves into ENQs. I changed logic to do an I/O Purge after X no. of seconds - this caused IOS to do a Halt Subchannel - which also didn't end. Then user started seeing Halt Subchannel Pending messages. User went ballistic - your product is melting/destroying my processor. I ended up disabling the feature that did the I/Os. Sigh... HSM is a likely candidate for initial investigation.

It could also be reserved on the same system. But this would not block access from the same system, so START PENDING does not apply here. Of course, there can be contention by means of an ENQueue, but that would just block a task long before an I/O is even started.

Cheers Jan Try looking for a hardware reserve from a sharing system. I can't see all the error msg... looks like it might have ended with RESERVED BY xxx, where xxx is another system's name? It could also be reserved on the same system.
