HP StorageWorks Scalable File Share System Installation and Upgrade Guide Version 2.2

Choosing the root user password 2–29
2.10 Choosing the root user password
When the HP SFS software is installed, the servers are configured with the password for the root user set
to secret. Instructions are provided in the relevant sections for changing this password.
HP strongly recommends that you change the root user password. When choosing a new password,
consider the following points:
• Do not keep the default secret password.
• Do not use words from the dictionary.
• Do not use the name of people, places, or things that can easily be connected with you or your
company.
2.11 Understanding license file concepts
For each license that you order from HP, you receive a license file when you redeem the license. Depending
on your system configuration, you may receive more than one license (this is explained later in this section).
When you install your HP SFS system, you use the licenses you received from HP to create a license file and
then install that license file on the system. The instructions for obtaining and installing license files are given
as part of the installation instructions in Chapter 4, Chapter 6, Chapter 7, and Chapter 8 of this guide.
This section describes the contents and purpose of the license files.
Each license file that you receive from HP contains an increment. There are five types of increment, and each
one enables a specific piece of functionality, as follows:
SFSMDSOST (MDS+OST license; minimal system) Allows you to create and start a 2TB file
system based on capacity class (SFS20 enclosure) storage on an HP SFS
system that contains two servers. The OST services must not run on Object
Storage Servers; instead, they must run on the administration and MDS servers.
SFSMDSENT (MDS license) Allows you to start a file system that is based on enterprise class
(EVA4000) storage.
SFSMDSCAP (MDS license) Allows you to start a file system that is based on capacity class
(SFS20 enclosure) storage.
SFSOSTENT (OST license) Allows you to create a file system that is based on enterprise
class (EVA4000) storage.
SFSOSTCAP (OST license) Allows you to create a file system that is based on capacity class
(SFS20 enclosure) storage.
The following are the valid license combinations:
• A combined MDS and OST license (SFSMDSOST) for systems where there are only two servers and
SFS20 storage is used.
• One MDS license (SFSMDSENT) and one or more OST licenses (SFSOSTENT) for systems where
EVA4000 storage is used.
• One MDS license (SFSMDSCAP) and one or more OST licenses (SFSOSTCAP) for systems where
SFS20 storage is used.
Each SFSOSTENT and SFSOSTCAP increment (OST license) also specifies (in terabytes) the amount of
storage licensed by that increment. The create filesystem command does not allow you to create a
file system (or file systems) that would result in the aggregate file system size exceeding the total amount of
storage licensed by the combined OST licenses.
