Storage subsystem profile
Configuring a DS5000 storage subsystem is a complex task and it is therefore essential to
document the configuration. The profile data contains information that could help recover part
or all of the configuration of the DS5000 storage subsystem, and can also be saved in a file
known as the
subsystem profile
. This profile stores information about the controllers, attached
drives, and enclosures, and their microcode levels, arrays, logical drives, and storage
partitioning.
1. To obtain the profile, open the Subsystem Management window and select Storage

2. The information is gathered from various components when you request the profile. The
profile can be saved locally and included in the documentation to maintain a change
history for the storage system.
We recommend that you save a new version of the profile and store it securely whenever a
configuration change takes place. Even in the case of a complete configuration loss, you
can restore the arrays and logical drives configuration as well as the mappings for the
storage partitioning using the profile information.
Tip: You should save a new profile every time you change the configuration of the DS5000
storage system, even for minor changes. The profile is stored in a location where it is
available even after a complete configuration loss, for example, after a site loss.
