There are offline or
missing virtual drives
with preserved cache.
Please check the
cables and ensure that
all drives are
present.
Press any key to enter
the configuration
utility.
The controller preserves
the dirty cache from a
virtual disk if the disk
becomes offline or is
deleted because of missing
physical disks.
This preserved dirty cache
is called pinned cache, and
is preserved until you
import the virtual disk, or
discard the cache.
Use the
<Ctrl><R>
utility to import the
virtual disk or discard
the preserved cache.
For the steps used to
manage preserved
cache, see "Managing
Preserved Cache" on
page 96.
