x4 SAS port. This bicolor LED displays the status of any external SAS port.
The LED indicates whether all links are functional or only partial links are
functional.
Table 7-9 describes the patterns for the PERC 6/E adapter port status.

This is a known issue. An unsupported
command is entered through the user
application. User applications attempt to direct
Command Descriptor Blocks to RAID volumes.
The error message does not effect the feature
functionality.
The Mode Sense/Select command is supported
by firmware on the controller. 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.
