RAID 5 Array randomly rebuilds

hello everybody.

 

i have a ProLiant DL380 G7 server with two RAID arrays.

about once a week the second array (RAID 5 SATA) goes recovery mode and starts rebuilding the first physical drive.

rebuild takes something like 12 hours, then everything goes back OK.

 

what the hell is goin' on?

 

- here  is what happens:

# hpacucli ctrl slot=0 show config

[...]

   array B (SATA, Unused Space: 0 MB)
      logicaldrive 2 (2.7 TB, RAID 5, Recovering, 19% complete)
      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SATA, 1 TB, Rebuilding)

[...]

 

- and then everything is OK again:

# hpacucli ctrl slot=0 show config

Smart Array P410i in Slot 0 (Embedded)    (sn: 50014380095A23E0)

   array A (SAS, Unused Space: 0 MB)


      logicaldrive 1 (136.7 GB, RAID 1, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 146 GB, OK)
      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 146 GB, OK)

   array B (SATA, Unused Space: 0 MB)


      logicaldrive 2 (2.7 TB, RAID 5, OK)

      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SATA, 1 TB, OK)
      physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SATA, 1 TB, OK)
      physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SATA, 1 TB, OK)
      physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SATA, 1 TB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250 (WWID: 50014380095A23EF)

- server firmware version is as follows (hpasm:

ROM version   : P67 05/05/2011

Smart Array P410i in Slot 0 (Embedded)
   Hardware Revision: Rev C

Re: RAID 5 Array randomly rebuilds

Hello, 

 

HP ADUreport might be able to tell you some more details.

Maybe some disk is intermittently having problems. Connection problems etc.

Also HP IML.

 

There are a few firmwares released since 3.66B, see this link:

There are also updates to the disk drive firmware:

I haven't gone through the release notes of the firmwares so maybe they don't apply to your problem.

Re: RAID 5 Array randomly rebuilds

As Johan said, get and ADU report. I'd also shut down the system (so as to not initiate a rebuild) and re-seat the drives in case there is a bad connection.
