pair. With this configuration, you can:

The following figure shows an example of a volume functioning as both a TC390 M-VOL and an SI390
T-VOL.
NOTE: This configuration does not allow SI390 and TC390 to copy at the same time. Create the SI390
pair first, and then split the pair before creating the TC390 pair. You must suspend the TC390 pair to
resync the SI pair.
