P222 parity initialization for more than a month?

Recommended Posts

Hello everyone and I am new to this forum.

 

I have my Gen8 and P222 running for over a year without any problem. I setup my P222 with 3T x 4 WD RED in Raid 5 mode. Recently, I noticed there is an error message for my P222 card. Please check the photos attached.

 

At first I didn't pay too much attention since it was not critical information. Now it has been more than a month, is there anything I can do to fix it? The disk performance has been decreased noticeably. 

 

Thanks in advance for any help

Have you gone into ACU or SSA to check drive health? It looks like the controller is seeing media errors. This issue you are seeing comes up from time to time and it seems to be related to a failing drive. The controller keeps trying to finish parity initialization, but keeps getting media errors that it need to try to fix. Do you have a good backup of your data?

Thanks for your reply. I don't have any backup of my data. The logical volume of my Raid 5 is still accessible but preference decreased. A silly question, How can I go into ACU or SSA? I believe the screenshot I took is from Smart Storage Administrator, if that is SSA. Which part of information should I look for to take further action?

 

Thanks again.

Have you reviewed the diagnostic report in SSA? The screen above shows the major errors, but the report may have more info.

What OS are you running? If you are running a supported OS you could try HPE Insight Diagnostics:

I will see if I can find anything else to try.

It looks like most people with the 1716 error resolve it by backing up their data, removing the array, build a new array and restore the data.

It is a very big report with tons of information which I don't understand.:wacko:

 

I attached the report if you can check it for me. BTW, I am running Windows Server 2012 R2 Essential, which can't be found on HPE insight diagnostics tool.

Much much appreciated.

I gave it a brief look. The drives are listed near the bottom. You can search the text file in notepad. Drives are listed as 2I:1 2I:2 2I:3 2I:4. The drives look OK except for 2I:3

Last Failure Reason                  Write Retries Failed (0x2b)

Errors Logged                        27782 (0x00006c86)

 

Your other drives have no failures and each only shows 45 errors. The media errors reported in error code 1716 could relate to the failed write retries listed above. If it was my server I think I would replace that drive, but first I would confirm that I had a clean backup. When you replace a drive the controller will rebuild the RAID5 array. That will cause a lot of drive activity. The rest of your drives seem fine, but you may lose a second drive during rebuild and then you would lose your data.

Disclaimer: I did not study the log file in depth. I am not sure that swapping the drive will fix the issue. I am just telling you what I would try.

This is super super helpful!

 

I am going to backup my files, about 4T in total, to an external drive and then to rebuild my array.

Few questions here:

1. It seems that Raid 5 is very vulnerable. You suggest I backup data first in case during the rebuilding, there are chances that second drive fails, what is the point to have Raid 5 as data redundancy ?

2. After I backup my data, if I switch from Raid 5 to Raid 10. Does singel drive readable if I connect one of these drives from Raid 10 array to other normal PC?

3. Any other better suggest? I have 4 x 3T drive and my data is about 4-5t in total.

 

Again, thanks so much for helping me out.

1. RAID is not a backup, you should always have a backup of your data regardless of the RAID you use. RAID5 is capacity efficient (9TB usable with four 3TB drives)   and can sustain a single drive failure, but the array rebuild puts a great deal of activity/load on the drives. There is no data redundancy in RAID5.

2. RAID10 is less capacity efficient than RAID5 (6TB usable with four 3TB drives) it can sustain a single drive failure and sometimes two drive failures and not lose data. RAID10 is much easier to rebuild as there is no parity calculations. Drives in a RAID controller based RAID10 are not portable to a normal PC. The RAID sets are portable to another HP Smart Array controller.

3. In your current setup RAID10 would be my preferred setup.  

There is some good info in this document on replacing drives and rebuilding array,

      Hello,
       
      I have recently purchased a Gen 8 Microserver with plans to install OMV.
       
      I did a bit of reading prior (and having also got a N54L) picked up a P222 Smart Array Raid card so I could also use RAID 5 on my 4 x 8Tb WD Red Plus drives.
       
      I also had lying around an old 2.5" 160Gb WD Blue drive which I was going to use for the OS.
       
      All the extra parts and cables have been installed (power from FDD to SATA for the HDD) and everything appeared ok.
       
      I have configured the 160Gb drive as Raid 0 in SSA on the B120i internal controller.  However when I attempt to install OMV, it comes up with an error message when installing the files onto this drive.
       
      Is it possible to install an OS onto the ODD drive and boot from it.  I have read elsewhere that I may need to use either a USB or microSD card as the boot device.
       
      Does this drive need to be a SSD?
      Since I have plugged the SAS cable into the P222 card, I was able to configure the drives in RAID 5, however, I am now getting a error under iLO saying System Health Degraded.
       
      Upon further investigation, it appears to be from the P222 card, getting Error 1797 - Slot 1 Drive Array - Write-Back Cache Backup Previously failed, caching is disabled at startup.
       
      When I open the SSA application, there is a Warning - 823 - The cache for Smart Array P222 in Slot 1 has been disabled because the backup operation failed.
       
      I am unsure what could be causing this as the card has the cache and battery (both being detected).  I have tried removing the cache and reinstalling it but didn't make a difference.
       
      Is this a hardware issue?  I only just purchased the card so will contact the seller to advise of a faulty card.
       
      Any help on either of these would be greatly appreciated.
       
      Thanks

      Hi All,
       
      Is it possible for the P222 Raid Card to pass through storage on the Mircroserver Gen8 esxi 7.0u build? 
      I cannot get my VM to see a datastore I have created after rebuilding my Gen8 from Windows to ESXI 7.0u
       
      Hope my query makes sense.
       
      Thanks

      Hi,
      it is a stormy weekend here, lots of rain, so i want to change some configurations in my gen8 with P212 smart array card
      my configuration:
       
      booting from odd bay 240 gb ssd 
      in gen 8 bays 1 and 2  raid 2x 3 tb
      bay 3 and 4 stand alone drives for server backup and client backups. All connected to b210
       
      an external box for 4 drives, all raid 0 connected to p212 external port.
       
      my changes include the following:
       
      replace P212 by P222.
      take connector from b210 and connect it to internal port P222
      connect external connector to P222
      connect ssd to b210 port 1 for higher speed.
       
       
      questions i am asking myself:
      a) will all arrays be recognized directly when connect to P222
      b) will set boot from ssd, guess i have to look in setup for boot disk
      c) can i add a second ssd, same size, and make it an raid 1 configuration, so port 1 and 2 from b210 are 1 boot disk?
       
      rgds
      Patrick
      Sorry, When writing b210, i meant b120i

      Hello! I put P222 on my Gen8 server, but I can not use RAID6. Can someone share the key?

      Hello
       
      I have a Micreoserver gen8 with a new P222 and 4 X 4TB WD red drives forming a raid6 array. The problem is i can hear a loud noise comming from HDD like a intense reading disk operation, but when disks suposly are idle. This happen periodicaly like each 15 minutos or so. I think this can be a checking disk operation from p222 raid card but is anoying and I'm not sure. Can you provide any hint to this?
       
      Thank You
