Hi,

It looks like the array is still doing the background initialization on the array, this may be why it will not let you do a consistency check.  

hi Josh,

well, I'm not so sure...

$ perccli /c0/v1 show init
Controller = 0
Status = Success

there are two more raid volumes in that chassis under a one H800. The whole lot:

DG/VD TYPE   State Access Consist Cache Cac sCC      Size Name
---------------------------------------------------------------
0/0   Cac0   Optl  RW     Yes     RWTD  -   OFF  512.0 GB
3/1   RAID10 Optl  RW     No      RWBC  R   OFF 18.188 TB
1/2   RAID0  Optl  RW     Yes     RWBC  R   OFF 38.195 TB
2/3   RAID0  Optl  RW     Yes     RWBC  R   OFF 12.731 TB
---------------------------------------------------------------

All these disks currently in raid10, plus one more, were before parts of a raid5 volume and all was a OK.
Although inconsistent the volume is in the OS and appears normal.

it's quite a puzzle to me.
thanks

What OS are you using? You may want to install server administrator. 

it's Centos 7.3

OS should not play any role here, right ?

Try installing OMSA and see if it lets you run a consistency check. http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=KJK52&fileId=3592543700&osCode=RHE70&productCode=poweredge-r730&languageCode=en&categoryId=SM

there is something troubling here happening:

this VD was created with omconfig:

would you, anybody @Dell know this error codes:

$ perccli /c1/v0 start cc

I've tried two different PE815, firmware on both is the same, DSU used.

Both systems have different chassis makes attached(although LSI in both I imagine).

I see this on both.

Hello, were you able to find solution or reason for this? Iam having the same trouble and there is not much to google about it :/

It is probably doing a background init as opposed to a regular foreground init. Check with:

perccli /c0/v1 show bgi

Once it's finished, you can start the cc. Which probably happened 5 years ago for the OP
