Jags, Is your GRS-plex set up properly to propagate ENQs and RESERVEs across all the systems in your shared DASD complex? IMHO, under normal conditions, you should not have hard RESERVEs on a disk impacting your systems.

Possible cause or action DOV0053 DEV -Z18RS1 93.0 % delay May be reserved by another system. DOV0061 DEV -Z18RS1 92.0 % delay May be reserved by another system. DOV0065 DEV -Z18RS1 91.0 % delay May be reserved by another system. The above exceptions shows lot of device contention due to which often we are facing a session hang. Also, Device display shows the status as BSY(busy). Could anyone please throw some light on the above issue.
