156 Implementing an Open IBM SAN
The space of the disk groups that contains ESS logical volumes that are assigned
to the selected host FC port show up in purple, and unused space in green.
Both host FC ports have no ESS logical volumes assigned to them in the disk
group in cluster 1, adapter pair four, loop B. This is indicated by the absence of
colors.
However, on the particular disk group space is allocated for volumes. This means
that there is an existing volume (or more), which is not yet assigned to any host
FC port. To make this allocated space visible, we press the View All Storage
button and see all the allocated space on the disk groups. This is shown in
Figure 2-110.
Figure 2-110 Unassigned volume(s) in disk group 2 of cluster 1 loop B
Allocated, but unassigned, volumes are indicated by the yellow colored space in
the disk group. The space in the other disk groups, that contains allocated and
assigned volumes shows up in the color red.
