Thank you all for the input. After trying and failing to make the MINIOP T user directory statement work, the ticket with IBM took a positive turn,
and have what I think is a good answer. They pointed me to CP Planning Manual section "Using HyperPAV Minidisks" which indicates for MDISK allocations (the way we are allocating space) z/VM will automatically use PAV if present. This means there is no need, as discussed in the SC33- 8414-00 manual, to try and cause the z/Linux guest to use PAV with COMMAN D DEFINE HYPERPAVALIAS, DASDOPT, or MINIOPT statements in the user director y.
