Resetting Statistics

You should reset statistics when you are monitoring performance, when you change
how you are using volumes, or when an event occurs that alters virtual disks and
volumes, including additions, deletions, and component failures.
As an Advanced user, you can reset to zero either or both of the following:
All virtual disk and volume statistics
■
All controller disk-drive error statistics, which are maintained by the controller
■
for each disk drive
To reset statistics for specific drives only, see "Disk Drive Error Statistics" on
page 174.
Note – You cannot reset port queue depth and last I/O size, which always show the
current values.
Description
Space on spare disk drives that are designated for use by a
specific virtual disk.
Space on spare disk drives that are designated for use by
any virtual disk.
Space on unassigned disk drives that are available for
creating new virtual disks, for expanding virtual disks, or
for use as spares.
This category is displayed if a disk drive was previously a
member of a virtual disk and contains old metadata,
making it a Leftover. When the metadata is cleared, the
drive becomes Available. See "Clearing Metadata From
Leftover Disk Drives" on page 136.
