Deleting SFS20 array information from the database 3–15
6. When you have finished unconfiguring (or reconfiguring) the array, shut down the servers, enable
them, and then boot them again, by entering the commands shown in the following example:
sfs> shutdown server south[3-4]
sfs> enable server south[3-4]
sfs> boot server south[3-4]
Because the servers are enabled, the services will run on the servers when the servers boot.
3.10 Deleting SFS20 array information from the database
When you unconfigure an SFS20 array, the array information is not deleted from the database. If the array
is being removed from the system, you must delete the array information from the database by entering the
command shown in the following example, where array
3
is deleted:
sfs> delete array 3
CAUTION: Deleting the array information from the database makes the array unusable. Use this command
only when an array is being disconnected from a server pair.
If you do not detach the SFS20 array from both servers, the next time either of the servers is rebooted, the
SFS20 array is discovered again. This creates a new array in the database; the new array has a different
number but the same serial number. If this happens, you can delete the array again using the
delete
array
command, because the array is not configured.
3.11 Managing licenses
This section describes how to manage licenses on your HP SFS system, and is organized as follows:
• Understanding license file concepts (Section 3.11.1)
• Viewing license information (Section 3.11.2)
• Adding or removing licenses (Section 3.11.3)
• Licensing additional storage capacity to the system (Section 3.11.4)
• Upgrading from an SFSMDSOST license (Section 3.11.5)
• Deleting all licenses (Section 3.11.6)
3.11.1Understanding 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 the HP StorageWorks Scalable File Share System Installation and
Upgrade 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.
