481
Error The periodic monitor of CompactFlash hardware detected an error. The controller was put in write-through
mode, which reduces I/O performance.
Recommended actions
• Restart the Storage Controller that logged this event.
• If this event is logged again, shut down the Storage Controller, remove the controller module from the
enclosure, replace the CompactFlash card (which is accessible from the rear of the controller module,
as shown in your product's User Guide), and reinstall the controller module.
• If this event is then logged again, replace the controller module.
Recommended actions:
Replace the controller module that logged this event.
483
Error An invalid expansion-module connection was detected for the indicated disk channel. An egress port is
connected to an egress port, or an ingress port is connected to an egress port.
Recommended actions
• Visually trace the cabling between enclosures and correct the cabling.

Warning No compatible spares are available to reconstruct this vdisk if it experiences a disk failure. Only vdisks
that have dedicated spares will start reconstruction automatically.
This situation puts data at increased risk because it will require user action to configure a disk as a
dedicated or global spare before reconstruction can begin on the indicated vdisk if a disk in that vdisk
fails in the future.
If the last global spare has been deleted or used for reconstruction, all vdisks that do not have at least one
dedicated spare are at increased risk. Note that even though there may be global spares still available,
they cannot be used for reconstruction of a vdisk if that vdisk uses larger-capacity disks or a different type
of disk; so this event may be logged even when there are unused global spares. If the dynamic spares
feature is enabled, this event will be logged even if there is an available disk that may be used for
reconstruction.
Recommended actions
• Configure disks as dedicated spares or global spares.
• For a dedicated spare, the disk must be of the same type as the other disks in the vdisk and at least as
large and should have the same or better performance.
• For a global spare, it is best to choose a disk that is as big as or bigger than the largest disk of its type
in the system and of equal or greater performance. If the system contains a mix of disk types (SATA,
SAS, SSD, for example), there should be at least one global spare of each type (unless dedicated
spares are used to protect every vdisk of a given type).
