Interconnect Cables

Host SCSI cables
Stop all I/O activities to the corresponding data path before replacing a host SCSI
cable.
SCSI cables
Drive side SCSI cables
You should stop all I/O activities to the controller module and power down the
controller module before replacing the drive side SCSI cables. If the failure caused
a disk tray to lose communication to the controllers, you will need to power cycle
the controller module to re-establish communication with the disk tray.

Subsystem Fault LED

The firmware turns the Subsystem Fault LED (
power supply, or temperature error condition occurs. Otherwise, the Subsystem
Fault LED is green. The Subsystem Fault LED is not turned off, even if the Global
Failure Indication and Global Warning Indication Flags are cleared by the SEND
GLOBAL FLAGS command issued by the initiator, until all the error conditions are
cleared.
A SEND GLOBAL FLAGS command will set the Subsystem Fault LED solid amber
when the "Global Failure" flag (byte 1, bit 1) is set. The Subsystem Fault LED will be
flashing amber when the "Global Warning" (byte 1, bit 2) is set.
