HP StorageWorks 2000 Series Reference Manual page 165

As an Advanced user, you can view the following categories of configuration
settings: general, RAID controller, EMP, security access to services, user
preferences, and Network Time Protocol (NTP).
To view miscellaneous configuration settings:
Select Monitor > Status > Advanced Settings > Misc Configuration.
The information is displayed in five panels.
The General Configuration Status panel shows the following information:
Background Scrub – Shows whether virtual disks are automatically analyzed to
find disk-drive defects. The default is Enabled. If Enabled, disk drives associated
with virtual disks are continuously analyzed and information about disk-drive
defects is reported and is stored in disk-drive metadata. If Disabled, virtual disks
are not automatically scrubbed. For more information, see "Enabling and
Disabling Background Scrub for Disks" on page 189.
Partner Firmware Upgrade – Shows whether the system automatically upgrades
firmware on one controller when a newer version of firmware is loaded on the
partner controller. The default is Enabled. If Enabled, the partner controller is
automatically upgraded. If Disabled, the partner controller must be upgraded
manually.
If directed by a service technician, a Manage user can disable partner firmware
upgrade on the Manage > General Config > System Configuration page.
Utility Priority – Shows the priority at which all system utilities run when there
are active I/O operations competing for the controller's CPU. The setting can be
High (default), Medium, or Low. The default is High. For more information, see
"Changing Utility Priority" on page 183.
Host Control Of Cache – Shows whether hosts are prevented from using SCSI
commands to change the system's write-back cache setting. Some
operating systems disable write cache. The default is Disabled. If host control is
Disabled, the host cannot modify the cache setting. For more information, see
"Controlling Host Access to the System's Write-Back Cache Setting" on
page 190.
Dynamic Spare – Shows whether the system can automatically take a properly
sized available drive to reconstruct a virtual disk when no spares are designated.
The default is Disabled. For more information, see "Managing Dynamic Spares"
on page 80.
