HP Array Controller HSG V8.7 Software - Manual (Page 129)

Creating Storagesets 3–51
n All configuration information normally saved when you restart
your controller except, the controller serial number, product ID
number, vendor ID number, and any manufacturing fault
information.
n Patch information
The save configuration option does not save the following
information:
n Software or hardware upgrades
n Inter-platform conversions
Considerations for Saving the Configuration
n Use the SET FAILOVER COPY= command to restore
configuration information in a replacement controller. See “Saving
Configuration Information in Dual-Redundant Configurations,”
page 3–52 for details.
n Do not remove and replace disk devices between the time you save
and restore your configuration. This is particularly important for
devices that you migrate from another system. The controller could
recover and use the wrong configuration information on your
subsystem.
n Save your subsystem configuration as soon as possible after
removing and replacing any disk devices in your subsystem. This
ensures that the devices always contain the latest, valid information
for your system.
n When you incorporate a spare into a storageset that you initialized
with the INITIALIZE SAVE_CONFIGURATION command, the
controller reserves space on the spare for configuration information.
The controller updates this information when the configuration
changes.
n You cannot use a storageset that contains user data to save your
subsystem configuration unless you backup and restore the user
data.
n If you previously configured storagesets with the
SAVE_CONFIGURATION option, you do not need to initialize
them again after you reconfigure your devices with a new
controller.
