system can continue to operate even if one Hard Disk Drive (2 drives in the case of RAID 6)
failed. However, we recommend you replace the failed Hard Disk Drive and perform
rebuilding as soon as possible (Hard Disk Drives are replaced by using hot swapping).
• The LED flashes green and amber alternately
Th
is indicates that a Hard Disk Drive is being rebuilt (not a defect). In a RAID S
ystem, the Hard Disk
Drive is automatically rebuilt upon replacing a broken Hard Disk Drive (auto build function). The LED
flashes green and amber alternately while a Hard Disk Drive is being rebuilt.
The LED goes off when rebuilding completes. If rebuilding fails, the LED flashes amber.
Important Observe the following precautions whenever you use the auto build function.
• Do not turn off or reboot the server while a Hard Disk Drive is being rebuilt.
• Wait at least 90 seconds before installing a Hard Disk Drive after removing one.
• Do not replace a Hard Disk Drive while another Hard Disk Drive is being rebuilt.
