Dirty cache data error message
Error Message:
The following virtual disks are missing: (x). If you proceed (or load the
configuration utility), these virtual disks will be removed from your
configuration. If you wish to use them at a later time, they will have to be
imported. If you believe these virtual disks should be present, please power
off your system and check your cables to ensure all disks are present. Press
any key to continue, or 'C' to load the configuration utility. The cache
contains dirty data, but some virtual disks are missing or will go offline, so
the cached data cannot be written to disk. If this is an unexpected error, then
please power off your system and check your cables to ensure all disks are
present. If you continue, the data in cache will be permanently discarded.
Press 'X' to acknowledge and permanently destroy the cached data.
Probable Cause: The controller preserves the dirty cache from a virtual disk if the disk becomes oine or is deleted because of
missing physical disks. This message indicates that some congured disks were removed. If the disks were not
removed, they are no longer accessible. The SAS cables for your system might be improperly connected.
Corrective Action: Check the cable connections and x any problems. Restart the system. Use the HII conguration utility to import
the virtual disk or discard the preserved cache. For the steps to discard the preserved cache, see Clearing the
cache memory.
