Managing Arrays & Partitions
127
The number of drives you can add to an array depends upon the RAID level as shown in Table 3–2. You
also cannot exceed the maximum number of drives for each RAID level. See C.1, ”Creating Arrays”, on
page 105.
If you are expanding a multiple-partition array, you add free space at the end of the array. For more
information about partitions, see C.3.1, ”Understanding Partitions”, on page 133.
Note Once you start expanding array capacity, you cannot stop it. The expand function may take an hour or
more to complete, depending on the array type, array size, drive speed, and other processes running on
the Galaxy 65 Subsystem.
