Types of volumes
Besides normal volumes, you can use external volumes, custom-sized volumes and LUSE volumes.
When using external volumes, customized volumes, or LUSE volumes, note the following points:
• External
volumes
The license of External Storage is required.
• Custom-sized volumes
The license for VLL is required. To create a Business Copy pair with custom-sized volumes,
P-VOL must be paired with S-VOLs of the same capacity and the same emulation type.
• LUSE
volumes
The license for LUSE is required. To create a Business Copy pair with LUSE volumes, you must
make sure that P-VOL must be paired with S-VOL of the same size and the same structure.
For example, if the P-VOL is a LUSE volume where volumes of 1 GB, 2 GB and 3 GB are
combined in this order, you must make sure that the S-VOL is a LUSE volume where volumes
of 1 GB, 2 GB and 3 GB are combined in the same order.
•
Emulation type
Only volumes of the following emulation types can be used: OPEN-3, OPEN-8, OPEN-9, OPEN-E,
OPEN-K, OPEN-L, or OPEN-V.
•
Logical DKC (LDKC), CU, LDEV number
You can use volumes whose LDKC:CU:LDEV (a combination of an LDKC number, a CU number,
and an LDEV number) is within the range of 00:00:00 to 00:FE:FF, or 01:00:00 to 01:FE:FF.
