The UCS USRM has four hard drives configured in two RAID-1 mirrors. Hard drive 

bays 1 and 2 (counting from the left) require SAS 7.2K 1TB drives, while bays 3 and 4 

require SAS 15K 146GB drives. 
If a hard drive fails or is removed from its slot, an alarm is raised in the UCS USRM 

Web GUI and the UCS CIMC GUI. If so configured, an SNMP trap notification is 

also sent to the configured SNMP trap receiver(s). An audible alert also sounds until 

the hard drive is replaced and the RAID mirror is reconstructed. 
Caution: Failure to use the correct replacement hard drive can result in system 

failure and loss of data. Use only Cisco UCS USRM hard drives as replacement parts. 
A hard drive failure is indicated by a solid yellow warning light on the failed hard 

drive, and by a continuous beeping tone. 
Note: In the event of a hard drive failure, system performance may be degraded, and 

failure of the remaining hard drive in the pair will result in system failure and loss of 

data. 
Shortly after the hard drive is replaced, the yellow warning light blinks while the 

hard drive is being replicated. A yellow warning light that does not change from 

steadily lit to blinking indicates that the system has not accepted the new hard drive. 

If this occurs, make sure that the drive is of the correct size and type for the bay, and 

try again. 
The system continues to beep while the hard drive is replicated. After replication is 

complete and the system returns to normal status, the yellow warning light ceases to 

flash and the audible alert stops beeping.
