Is my drive dead already?

[grob115]

Just saw the following screenshots on my vSphere client.  Can someone let me know:

1) If the two are related or they are referring to different things?

2) If they are related, why would a failure of one of the disks in a RAID 1 group be detected as a disconnection by ESX?

3) Is vSphere reporting an upcoming failure (drive isn't dead yet), or the drive is dead?

Hi Grob,

It looks like one of your physical disks composing your RAID 1 group failed. And it produced a 20 second period of unavailability of your storage.

It's a strange behavior of such a redundant disk configuration. What RAID controller are you using? Check its configuration and verify that you use the latest firmware.

Good luck.

Regards

i would bring the host know to check from the raid manager to ensure the the right faulted disk is being replaced asap ..

Yeah on the first screenshot the drive comes up as predictive failure.  Get that drive replaced ASAP.

Okay it's replaced.  Questions:

1) After 8 hrs I'm still seeing this.  Any idea why the bolded messages are not changing to indicate KS67 ONLINE?

    I'm also not seeing the description RAID 1 Logical Volume .........

    Is this due to the 2nd drive is still being re-built by the RAID controller?  Does it take that long even after 8 hrs already?

Before maintenance
Controller 0 (SAS6IR)
Drive 0 on controller 0 FW: KS67 - ONLINE
Drive 1 on controller 0 FW: KS67PREDICTIVEFAILURE
RAID 1 Logical Volume 0 on controller 0.  Drives(0,1) - OPTIMAL

After maintenance
Controller 0 (SAS6IR)
Drive 0 on controller 0 FW: KS67 - UNCONFIGURED GOOD
Logical Volume 0 on controller 0 -

2) So the text "PREDICTIVEFAILURE" actually means it's dead, not going to die?

3) The controller is a SAS6IR apparently.  Any idea if this is a good/bad controller?  Anyway I can check it's firmware from vSphere client?
