                       There is a problem with the system software on this Storage Processor (ADMIN). 
                       To attempt to correct this problem: Run Data Collection, check all cables, 
		   reboot each SP, and lastly try Reimaging each Storage Processor (SP). 
		   If the Service Code is shown below and is set to 0xFC12CDD1, 
		   some part of the system is Cache Dirty so contact support for resolution.

* Hint Code: Dart root LUNs are cache dirty, escalate to fix cache dirty (code 0xFC12CDD1)

* SP Service Hint Code: 0xFC12CDD1  -->解决方法

Technicians have SSH into each SP and run the following: svc_cdca
 --list-cdca (list all cache dirty luns for current SP, 
 clear any cache dirty luns for current SP, 
 prepare any system luns for auto fsck.) Still no results as the SP's continue to reboot randomly.
