9.1.4 Connection lost

If the management connection from the management station to the storage server is lost, the
icons and text change, and an additional line appears in the box to notify you of this
(Figure 9-8). If only the management connection is lost, the attached hosts can still access
data on the disks, but you will not be able to manage your subsystem or to receive alerts. The
subsystem summary will display the last known state of the subsystem, but you will not be
able to perform any administrative operations.

9.2 Hardware components

Below the status box is an overview of the installed hardware components (Figure 9-9), that
is, the physically installed components in this storage subsystem. The upper part of the box
shows the number of installed controllers and the number of connected enclosures. The lower
part of the box shows the number of installed hard drives, the drive type, and an overview of
the hot spare drives.

The box also includes the following three links included to more detailed information:

9.2.1 Storage Subsystem Profile

Configuring a storage server can be a complex task - it is essential to document the
configuration and every configuration change. This documentation can be saved in a file
known as a subsystem profile. This profile stores information about the controllers, attached
drives and enclosures, microcode levels, arrays, logical drives and storage partitioning. To
generate the subsystem profile, click the Storage Subsystem Profile link in the Hardware
Components box (Figure 9-9). The information will be gathered from the various components
and the profile window will appear (Figure 9-10). Use the Save As button to save the profile
locally, to help document a change history of your storage subsystem. It will be saved as a
text file. You can look at the profile laters, as described in 13.1.3, "View Storage Subsystem
Profile" on page 293.
