Support for PAV is now available
Parallel Access Volume (PAV) is an optional licensed feature of the IBM System Storage DS8000 and DS6000, and IBM TotalStorage ESS series. It enables a single System z server to simultaneously process multiple I/O operations to the same volume.
PAV support is now available in z/VSE V4.2 with APAR DY46953/PTF UD53399 (01C) and UD53400 (01J).
Note: When running under z/VM and using z/VM's PAV minidisk support the ALIAS minidisks must be defined in the CP Directory for the guest (MINIOPT PAVALIAS). Using the CP command DEFINE PAVALIAS to dynamically define an alias might lead to z/VSE system hangs. |

z/VSE 4.2.0:
During Fast Service Upgrade to z/VSE 4.2.0 VSE/POWER may terminate with message 1Q000 instead of intended message 1Q05I PAGEABLE AREA [nnnK] TOO SMALL... . This will happen when SIZE of VSE/POWER partition taken from previous system is too small and VSE/POWER can not load all of its phases.
If this this happens during step 2 of FSU, you should restart the old system and increase the VSE/POWER partition SIZE in FSU dialogue by specifying "OWN POWER PARAMETERS......... 1 (YES)" and then providing a larger SIZE (at least 1200K). After FSU or installation make sure that your ALLOC.PROC specifies SIZE=1400K (or more) for the VSE/POWER partition. For details of VSE/POWER partition usage see here. To correct message 1Q000 install DY46901. |
