| Notes:
a. If mapping an external volume with more than 4 TB by using a virtual volume for which Data Direct Mapping is enabled: 16,777,216 blocks b. If mapping an external volume with more than 4 TB by using a virtual volume for which Data Direct Mapping is enabled: 549,755,813,888 blocks c. For 3380-A and 3390-A, a control information area is required for every 1,113 cylinders. |
