NOTE:
might not be able to create a CV with the same capacity as the internal XP LDEV (B) because
Volume Manager does not allow you to specify the capacity in blocks. In this case, you cannot
create a Continuous Access XP pair.

Copying data to external disk arrays (setting external LUs as S-VOLs)

For A, B, and C in the following description, see
To adjust the external LU's capacity to create a pair:
1. Map the external LU (A) as an internal XP LDEV (B) of the disk array. Set the emulation type to the same
as the copy source volume (C).
2. Check the capacity of the internal XP LDEV (B) to which the external LU (A) is mapped. If the mapped
internal XP LDEV's (B) capacity is not same as the copy source volume (C), use Volume Manager to
create a CV with the same capacity as the copy source volume (C) out of volume (B).
3. Create a copy pair.
