|---|---|
| Volume type | DP-VOL (V-VOL) The LDEV number is handled in the same way as for normal volumes. |
| Emulation type |
3390-A |
| Maximum number of DP-VOLs |
Up to 63,232 per pool. Any number of available DP-VOLs can be associated with a pool. Up to 63,232 volumes per system. If external volumes and V-VOLs are used, the total number of external volumes and V-VOLs must be 63,232 or fewer. |
| Volume capacity |
For 3390-A, volume capacity from 1 cyl to 1,182,006 cyl per volume. Total maximum volume capacity of 11.1 PB per storage system. |
| LDEV format |
When you format a DP-VOL, the storage system releases the allocated page area in the DP-VOL. The quick format operation cannot be performed. If the LDEV format is applied to V-VOLs that are enabled for full allocation, the used capacity of the pool is not changed before the LDEV format is applied. |
