Creating an IM Volume
To create an IM volume with the LSI MPT* SAS BIOS Configuration Utility, follow
these steps:
1. On the Adapter List screen, use the arrow keys to select an adapter.
2. Press <Enter> to go to the Adapter Properties screen, shown in Figure 10.
Figure 10. Adapter Properties Screen
3. On the Adapter Properties screen, use the arrow keys to select RAID Properties on
the screen and press <Enter>.
4. When prompted to select a volume type, select Create IM Volume.
The Create New Array screen shows a list of disks available to be added to a
volume.
5. 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 <+> or <-> keys, or the space bar.
When the first disk is added, the utility 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 512 KB 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 <+> or <-> keys, or the space bar.
Figure 11 shows an IM volume configured with one global hot-spare disk.
