Chapter 2. IBM TotalStorage Enterprise Storage Server configuration 103
There are different colors to indicate the state of the disk groups. At the upper
right of the screen, shown in Figure 2-33, a legend is displayed, which explains
what the different colors in the disk groups represent.
Figure 2-33 Legend of the disk group status colors
The colors indicate the following:
Purple, Host Storage Disk storage that contains ESS logical volumes that are
assigned to a specific (selected) host FC port. This
displays only if a host FC port is selected first.
Red, Assigned Disk storage that contains ESS logical volumes that are
assigned to other than the selected host FC port, or that
are assigned to any host FC port, when no host FC port
was selected. This happens, for example, when we select
a specific disk group or when we press the View All
Storage button.
Yellow, Unassigned Disk storage that contains ESS logical volumes that were
assigned to host FC ports before and then were
unassigned. Those ESS logical volumes can be assigned
to any host FC ports.
Green, Not Allocated Disk storage that contains no ESS logical volumes. This
storage can be used to define and assign ESS logical
volumes.
We will explain more details of the Storage Allocation — Graphical View panel
later on as we progress with our configuration and the panel shows the
information relating to our configuration changes.
Using the Storage Allocation — Tabular View panel
To get a detailed view of the ESS logical volumes later on, we will use the
Tabular View button to get to the view as shown in Figure 2-34.
