How to Specify the LDEV Capacity

When you specify the LDEV capacity for the AddVolumeSetting tag in a spreadsheet, follow the instruction in this section depending on the emulation type.

•When the emulation type is OPEN-V:

◦Specify the value in the range of 96000 and 8589934592.

◦An LDEV is created from where a slot starts. Therefore, if you specify the LDEV capacity indivisible by the slot size (512 blocks), an adjustment area will be created between where an LDEV ends and where the next LDEV starts. This adjustment area cannot be used as an LDEV.

You can calculate the adjustment area using the following equation: Adjustment area capacity = LDEV capacity 512 × 512 – LDEV capacity

The value enclosed in two upward arrows () must be rounded up to the nearest whole number.

◦Make sure that the capacity of the external volume is greater than or equal to the capacity that is the sum of the total capacity of all the LDEVs in the external volume and the total capacity of the adjustment areas.

Figure 40 (page 111) gives an example of creating four LDEVs of 100,000 blocks each. In this case, the required capacity of the external volume is 401,056 blocks.
