Inconsistent RAID5


Good day.

We have a small RAID5 on an Intel(R) RAID Controller SRCSAS18E comprised of 4 Seagate Cheetah ST3600057SS drives. The array seems to be functioning fine, however the command:

# storcli /c0 /v1 show all

results in part:


/c0/v1 :



DG/VD TYPE State Access Consist Cache sCC Size Name


1/1 RAID5 Optl RW No RWTC - 1.633 TB


Cac=CacheCade|Rec=Recovery|OfLn=OffLine|Pdgd=Partially Degraded|dgrd=Degraded

Optl=Optimal|RO=Read Only|RW=Read Write|B=Blocked|Consist=Consistent|

R=Read Ahead Always|NR=No Read Ahead|WB=WriteBack|

AWB=Always WriteBack|WT=WriteThrough|C=Cached IO|D=Direct IO|sCC=Scheduled

Check Consistency


From Google I understand that a lack of consistency means problems with parity. What I have not been able to figure out, and what I am looking for here is what can I do about it?
