Probable Cause: The message indicates that some configured disks were removed. If the disks were not removed, they
are no longer accessible. The cables from the PERC controller to the backplane might be improperly
connected.
Corrective
Action:
Check the cable connections and fix issues if any. Restart the system. If there are no cable problems,
press any key or <C> to continue.
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 offline or is deleted
because of missing physical disks. This message indicates that some configured disks were removed. If
the disks were not removed, they are no longer accessible. The cables from the PERC controller to the
backplane might be improperly connected.
Corrective
Action:
Check the cable connections and fix any problems. Restart the system. Use the HII configuration utility to
import the virtual disk or discard the preserved cache. For the steps to discard the preserved cache, see
Clear the cache memory.
Discovery error message
Error Message:
A discovery error has occurred, please power cycle the system and all the
enclosures attached to this system.
Probable Cause: This message indicates that discovery did not complete within 120 seconds. The cables from the PERC
controller to the backplane might be improperly connected.
Corrective
Action:
Check the cable connections and fix any problems. Restart the system.
Drive Configuration Changes Error Message
Error Message:
Entering the configuration utility in this state will result in drive
configuration changes. Press 'Y' to continue loading the configuration
utility or please power off your system and check your cables to ensure all
disks are present and reboot.
Probable Cause: The message is displayed after another HII warning indicating there are problems with previously
configured disks and you have chosen to accept any changes and continue. The cables from the PERC
controller to the backplane might be improperly connected.
Corrective
Action:
Check the cable connections and fix any problems before restarting the system. If there are no cable
problems, press any key or <Y> to continue.
