0000 0 Structure $VDEV Relocation mapping for HCPVDEV
00000003 $VDEV_VER 3 $VDEV mapping version.
$VDEV_VER is independent of the
CP level and need only be changed
when this DSECT is changed. The
convention is to increment by 1.
0000 0 Signed 2 $VDEV_HDRL Header length (in bytes)
0002 2 Signed 2 $VDEV_BITL Length of mapped bits (in bytes)
0004 4 Signed 4 * Reserved for future use
00000008 $VDEV_HDLN *-$VDEV Length of header (bytes)
Bit map: Contains the VDEV flags that are subject to
relocation. These bits are defined sequentially,
regardless of how they are defined in HCPVDEV.
This yields a consistent mapping that ensures
compatibility when a guest is relocated between
systems at differing service levels.
Names in the comments column indicate the control
block byte which contains the flag. This name is
subject to change if the flag definition changes.
====> NEVER change bits which already exist here.
====> NEVER change the order of bits in this section.
====> ALWAYS add new bits at the end of this section,
together with new flag bytes as required.
