Re: Hyperpav Error on Linux side
Problem as you're experiencing went away with RedHat 6.5 and higher. For RedHat /etc/dasd.conf seems to work well if HPAV address is placed before real device mdisk . Example: 0.0.0813 use_diag=0 readonly=0 erplog=0 failfast=0 0.0.9EE0 use_diag=0 readonly=0 erplog=0 failfast=0 Also, HPAV base must be full pack starting at Cyl 0.

Re: Hyperpav Error on Linux side
Hi Tito, just a guess: You defined 200 for base 9998 which is on device D279. This means, the HyperPAV alias would be valid for 9998, , and 999A. In all the examples I seen in the web, when using different pools, the first two digits of the virtual address for the different pools also represent a different number. I would try to use something like 9A98, 9A99, and 9A9A as virtual base devices and something like 9A9F as virtual HyperPAV alias device address for real devices D279, D27A, and D27B. Starting with SLES11-SP3, there is also the utility dasdstat available that give more information about the current usage and statistics of HyperPAV devices.
