LED Behavior Patterns

The external SAS ports on the PERC 5/E Adapter have a port status LED per x4 SAS port. This bi-color
LED displays the status of any external SAS port. The LED indicates whether all links are functional or
only partial links are functional. Table 6-7 describes the patterns for the port status.

Audible Alarm Warnings

An audible alarm is available on the PERC 5/E Adapter to alert you of key critical and warning events
involving the virtual disk or physical disk problems. You can use the Basic Input/Output System (BIOS)
Configuration Utility to enable, disable, or silence the on-board alarm tone.

NOTE:

Silencing the alarm stops only the current alarm, but future alarms will be sounded. To permanently disable

the alarm, select the

disable alarm option.

These error messages are caused by an unsupported command coming directly
from the user application. This is a known issue in which user applications try to
direct Command Descriptor Blocks to RAID volumes. This error message has no
effect on the user and there is no loss of functionality due to this error.

The Mode Sense/Select command is supported by firmware on the PERC 5.
However, the Linux kernel daemon is issuing the command to the virtual disk
instead of to the driver IOCTL node. This action is not supported.
