Best practices on resolving a faulty pairity drive when you have 2?

Featured Replies

I find lots of suggestions on how to resolve a parity situation when you have one parity drive, but no specifics when you have more than one. I'm unsure if anything is different about the process. I recently had one of my two parity drives fail and I'm apprehensive about doing much of anything without a little guidance. 

 

Here is what SMART is throwing:

 

ATA Error Count: 2
	CR = Command Register [HEX]
	FR = Features Register [HEX]
	SC = Sector Count Register [HEX]
	SN = Sector Number Register [HEX]
	CL = Cylinder Low Register [HEX]
	CH = Cylinder High Register [HEX]
	DH = Device/Head Register [HEX]
	DC = Device Command Register [HEX]
	ER = Error register [HEX]
	ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 2 occurred at disk power-on lifetime: 10463 hours (435 days + 23 hours)
  When the command that caused the error occurred, the device was active or idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  40 51 00 b8 96 01 0e  Error: WP at LBA = 0x0e0196b8 = 234985144

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name
  -- -- -- -- -- -- -- --  ----------------  --------------------

Any suggestions would be most appreciated!

It's the same, just replace that parity disk and start the array to re-sync parity.
