Pair volumes
• Number of P-VOLs per S-VOL: one
• Number of S-VOLs per P-VOL:
For L1 pairs, a maximum of three S-VOLs per P-VOL.
For L2 pairs, a maximum of two S-VOLs per P-VOL.
(For information on pair-layers, see “Cascaded pairs” (page 8)).
• Volume Capacity: P-VOL and S-VOLs must have the same capacity.
• Supported volume types:
- Internal system volumes.
- External volumes. External Storage (Ext Stor) license required.
- Custom-sized volumes. VLL required. Pair volumes must have same capacity and
emulation type.
- LUSE volumes require LUSE license. BC S-VOLs must have the same size and structure
as the P-VOL. For example, if the P-VOL is a LUSE volume in which volumes of 1 GB,
2 GB, and 3 GB are combined in this order, the S-VOL must also be a LUSE volume
with volumes of 1 GB, 2 GB, and 3 GB combined in the same order.
• MU number (mirror unit number):
- For an L1 pair, use 0, 1, or 2.
- For an L2 pair, use 1 or 2.
• Sharing volumes with other software products is supported. See “Sharing Business
Copy volumes” (page 23).

- Continuous Access Journal (Cnt Ac-J) journal volumes.
- Virtual volumes (except Thin Provisioning volumes).
- Pool volumes.
Per storage system: 16,384 pairs (when one S-VOL per P-VOL). Actual number is based
on amount of additional shared memory. See “Planning number of pairs” (page 13) for
further information.
