When adding the "Largest Free Space"
In the "Largest Free Space" field for the RAID group, the largest free space that is managed in the ETERNUS DX
is displayed after rounding off to two decimal places.
For example, if "10.00GB" is displayed for "Largest Free Space", the actual largest free space managed in the
ETERNUS DX may be between "9.995GB" and "10.004GB". The ETERNUS DX replaces (adjusts) the value
entered by the user to the actual largest free space value managed in the ETERNUS DX. This adjustment
enables the use of the largest free space with minimal waste.
However, if the value is entered in a different format (unit or digits) for the "Largest Free Space", the capacity
is not adjusted. Depending on the largest free space managed on the ETERNUS DX, there may be situations
when adding a specified capacity may not be possible.
[Example 1] If the "Largest Free Space" is "10.00GB" and the largest free space managed in the ETERNUS DX is
"9.995GB", the following situations occur.
• When entering "10.00GB" for the capacity, "9.995GB" is added.
• When entering "10.000GB" or "10240MB" for the capacity, an input error occurs.
[Example 2] If the "Largest Free Space" is "10.00GB" and the largest free space managed in the ETERNUS DX is
"10.004GB", the following situations occur.
• When entering "10.00GB" for the capacity, "10.004GB" is added.
• When entering "10240MB" for the capacity, "10240MB (10.00GB)" is added.
