DASD Support

Effective immediately, VSSI will only be providing product CKD support for 3390 disks. The affected disk configurations include:

. TPF and z/Linux BASE devices intercepted by the VPARS, ShadowDisk/Z,
and VTAPE products

. VPARS and VTAPE databases used as backing storage

3390 will be the only supported CKD device type going forward; older device types will be dropped from the code base as time permits  (i.e., during regular development cycles).

FBA device support is not impacted by this announcement.
