If XSTCTXAV falls below XSTLOTHR, the migration task will be kicked off. This value may change at the end of each migration. 52 34 Unsigned 4 STOXSG_XSTCYCLS Number of times the migrator has made a complete circuit of the cyclic list 56 38 Unsigned 4 STOXSG_XSTCPDAL Total number of expanded storage blocks migrated allocated to guests 56 38 Unsigned 4 STOXSG_XSTGUEST Alternate name to STOXSG_XSTCPDAL 60 3C Bitstring 8 STOXSG_XSTNOIO Number of expanded storage blocks that could be released by the migrator without having to perform I/O. These are pages that have not been modified since they were last written to DASD. Additionally, for user pages, the page must have been brought into storage as part of a block and not referenced. 68 44 Character 0 STOXSG_END
