Table 4: OCE Drive Additions by RAID Level
Expand Function (OCE)
Online Capacity Expansion (OCE) allows the user to expand the arrays without having to stop
I/O activity. Only one array can be expanded at a time, and the expansion of the array must
be completed before expanding another array.
NOTE: Once an OCE is started, it cannot be aborted!
The number of drives that can be added to an array depends upon the RAID level (Table 4).
To expand an array:
1. Select Expand Function from the Array Menu and press Enter.
2. Select Start Expand from the Expand Function options and press Enter.
3. Enter the number of drives and press Enter (Figure 14).
