Cannot. force HDD in Failed status to go offline

As described in guides and this forum, if a disk in RAID is to be replaced, shall be put offline.

/admin1-> racadm storage get pdisks -o -p state
Disk.Bay.0:Enclosure.Internal.0-1:RAID.Integrated.1-1
State = Failed
Disk.Bay.1:Enclosure.Internal.0-1:RAID.Integrated.1-1
State = Online
Disk.Bay.2:Enclosure.Internal.0-1:RAID.Integrated.1-1
State = Online
Disk.Bay.3:Enclosure.Internal.0-1:RAID.Integrated.1-1
State = Online
Disk.Bay.4:Enclosure.Internal.0-1:RAID.Integrated.1-1
State = Online

The command to put the failed disk offline reports error:
/admin1-> racadm storage forceoffline:Disk.Bay.0:Enclosure.Internal.0-1:RAID.Integrated.1-1
ERROR: STOR013 : One or more Storage device(s) are not in a state where the
operation can be completed.
Make sure the specified storage devices are in a state appropriate for
the requested operation and retry the operation.
There is no further explanation available, nor any info in the iDrac guide.

How to proceed in order to replace the drive?

Hi,

 

Drives that are in Failed state will not be able to force offline as they are already in failed state. Only Predictive Failure status can be force offline.

@DELL-Joey C​ Thank you for your response. It means I can just remove the drive and replace with a new one, without any further preparation for the replacement? The drive is a SAS HDD.

Thank you!

Vleck,
 
That is correct, you should be able to remove the drive, wait a minute and then insert the replacement. The only thing you will need to do, if the drive doesn't automatically start rebuilding, is to assign the replacement drive as a hotspare. As stated, this would only be needed if the replacement drive didn't automatically start rebuilding when inserted. 
 
Let me know if this helps.

Dear Mr. Chris H

I am now having the same issue with failed HDD on my RAID 1 (2x 4TB SAS) for DELL T140 while another HDD is in offline state.
Due to T140 is not the hot-plug model. Is it correct way to replace the failed drive without powering off the server? 
Will it rebuild the drive automatically or need me to start rebuilding it on Bios? 
Will my data will be back or gone if one HDD is failed and another is offline?

Thank you in advance for your support. 

Best regards
Sanal Ry

Sanalry,

 

Would you confimr some details for me?

 

What is the raid controller being used in the T140?

Was the offline drive forced offline, or was it just found like that? 
Does the offline drive show any sign of being a Predicted Failure?

Does the offline drive show as a Foriegn?

 

Let me know and we can go from there.
