New Raid 1 Disk Replacement Showing Predictive Failure

Question

Hi!

We have a Raid 1 disk configuration (PET320 server, PERC H310 adapter, hot swap) with one of the disks listed in a foreign state and with a predictive failure notice. The foreign disk was only showing blink and unblink options. I have replaced that disk with a new one (same capacity and speed) I ordered from Dell and the rebuild started seemingly ok.

Before the rebuild finished it showed an alert PRD16: Severity: Warning, Category: Storage, MessageID: PDR16, Message: Predictive failure reported for Physical Disk 0:1:0 on Controller 0 at Connector 0. A couple of hours later the rebuild completed. However, each day it is logging a PRD16 warning.

There are three tasks possible with this disk: blink, unblink and offline. This is a new disk. Any reason you can think of why it is showing predictive failure and anything I can do to try to fix this?

Thanks.

SJJP,

The first two things I would start with is to update the server, as well as the H310, to current on updates. After that is done then I would perform a Consistency Check on the Virtual Disk. To run the Consistency Check you need to start OpenManage from the OS and then do the following;

Locate the controller on which the virtual disk resides in the tree view.
Expand the controller object until the "Virtual Disks object is displayed.
Select the 'Check Consistency' task from the virtual disks's drop-down menu.
Click Execute.

After those two things the replacement drive shouldn't be showing the Predicted Failure, but if it does we need to run a SupportAssist report, so that I can check on a double fault or puncture to the parity.

Let me know what you see.

Hi Chris,

Thank you for your detailed reply!

I have run the updates on the server before replacing the disks. It seems there is a newly released PERC H310 firmware just last March so I will try to upgrade to that one later as well as perform a consistency check.

Just an additional question. In OMSA when I check the details of the physical disks, the new one's "capable speed" is listed as "not available" whereas the other had a speed listed. Does this matter?

Thanks again and will post an update here once I'm done with the checks.

Are they matching drives, if so are the firmware versions matching as well? Another thing is make sure the OpenManage version itself is the most recent version?

Check those, while you are doing that let me know the part number for the drive, as it could also be an issue with compatibility.

Thanks

Hi Chris,

The old one was a 3.5in drive but the new one is 2.5in in a custom kit. I requested same speed and capacity just to be sure and they had assured me it is compatible with the ones included when we purchased the server from them. OMSA used is the latest version.

I've done the driver and firmware updates. After restarting it gave me quite the scare, though. Couldn't boot into it. Inaccessible disks and no raid drives detected but the hard drive replacement was no longer flashing green/amber. After going to the configuration utility option it seemed to have booted correctly to my relief. Not sure what happened there but the logs showed PDs missing from configuration at boot. Seemed to have gotten loaded correctly afterwards based on the logs.

After logging in and running OMSA the drive is no longer showing as "foreign" but the capable speed is still listed as not available. I ran Check Consistency and it seemed ok. No issues but still no available capable speed.

Part Numbers:

CN0FPW68SGW007BQ005PA01 (new)

CN0W347K7262251Q00ZRA03 (old)

I just want to make sure the capable speed not getting listed will not turn into issues later on. I'd call local Dell support here to ask them but as it means I'll have to explain in a foreign language (I am not confident to use) I might just not explain it properly to them and run into more issues.

Again, thanks so much for the help!!!

It shouldn't be an issue. If those drives are 12gbps, then that is the reason the capable speed is blank, as read here.

Hello,

Was just looking for disk consistency option or workaround, and came to this link. What to do if the "Check consistency" task is not available in drop-down menu?

Locate the controller on which the virtual disk resides in the tree view.
Expand the controller object until the "Virtual Disks object is displayed.
Select the 'Check Consistency' task from the virtual disks's drop-down menu.
Click Execute.
