4.In the SELECT NEW ARRAY TYPE screen (Figure 7-6), select CREATE IM VOLUME.

The CREATE NEW ARRAY screen appears (Figure 7-7). This screen shows a list of disks available to be added to a volume.

5.In the CREATE NEW ARRAY screen move the cursor to the RAID Disk column and select a disk. To add the disk to the volume, change the NO to YES by pressing the + key, - key, or SPACE bar.

When the first disk is added, the SAS BIOS CU prompts you to either keep existing data or overwrite existing data.

6.Press M to keep the existing data on the first disk or press D to overwrite it.

If you keep the existing data, this is called a data migration. The first disk will be mirrored onto the second disk, so any data you want to keep must be on the first disk selected for the volume. Data on the second disk is overwritten. The first disk must have 512KB available for metadata after the last partition.

As disks are added the ARRAY SIZE field changes to reflect the size of the new volume.

7.[Optional] Add one or two global hot spares by moving the cursor to the hot spare column and pressing the + key, - key, or SPACE bar.

Figure 7-7shows an IM volume configured with one global hot spare disk.
