 NAME       : HCPRSEBK
 DESCRIPTION: Reset Event Block
 DSECT      : RSEBK
 FUNCTION   : To preserve reset event status and sense data or to
              save a Format F, Message B unit check for later guest
              reflection or to save a Format 3, Message F unit check
              for later guest reflection.
 LOCATED BY : RDEVRSE FIELD OF RDEV - Reset event status for that device
 CREATED BY : HCPPRF creates an RSEBK when processing a reset
              notification or a Format F, Message B unit check
              reported on a dedicated device or a Format 3,
              Message F unit check for a minidisk.  HCPGDS also
              creates a Format 3, Message F RSEBK for a minidisk.
 DELETED BY : HCPIOV deletes the RSEBK when the guest issues a sense
              (or other command) subsequent to draining reset notification
              status.
 RELOCATION CONSIDERATIONS : None
