User's Manual

• Set the add disk option to manual. See “Changing the Device Addition Policy” (page 69) for
more information.
• When adding multiple disk drives, add a disk and wait for its activity indicator (1) to stop
flashing (up to 90 seconds) before installing the next disk (see Figure 32 (page 68)). This
procedure must be followed to avoid unexpected EVA system behavior.

Creating disk groups
The new disks you add will typically be used to create new disk groups. Although you cannot
select which disks will be part of a disk group, you can control this by building the disk groups
sequentially.
Add the disk drives required for the first disk group, and then create a disk group using these disk
drives. Now add the disk drives for the second disk group, and then create that disk group. This
process gives you control over which disk drives are included in each disk group. Figure 33 (page
68) shows the sequential building of vertical disk groups.
NOTE: Standard and FATA disk drives must be in separate disk groups. Disk drives of different
capacities and spindle speeds can be included in the same disk group, but you may want to
consider separating them into separate disk groups.
