Chapter 2. IBM TotalStorage Enterprise Storage Server configuration 113
The rectangle representing the disk group is green to show that this is empty
storage. We also see that the host FC port icon row is empty. When selecting a
particular disk group, the row will only present and highlight those host FC port
icons that have ESS logical volumes assigned to it in the selected disk group.
Because there is no host FC port defined, there cannot be any ESS logical
volume defined and assigned.
When the disk group is selected, the Information field to the right of the panel
shows specific information such as the location of the disk group, the type of
storage the disk group is configured for and the available and allocated capacity.
This is shown in Figure 2-45.
Figure 2-45 Information window, for RAID 5 configured disk group
Here we see that the capacity of the disk groups that are configured as RAID
array, has changed to 210.48 GB. This is mainly because of the space for the
redundancy information that is now spread over the disks in the disk group and
because of the RAID configuration information.
