Copying data to external arrays (setting external LUs as S-VOLs)
For A, B, and C in the following description, see Figure 73 .
To adjust the external LU's capacity to create a pair:
1. Map the external LU (A) as an internal LDEV (B) of the local array. Set the emulation type to the
same as the copy source volume (C).
2. Check the capacity of the internal LDEV (B) to which the external LU (A) is mapped. If the mapped
internal 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.
