Predictive failure not rebuilding

li_andrew — Tue, 21 Jul 2009 22:49:58 GMT

Hi All,

Few days ago we had power off and power on the server. Since the power on, a disk status have changed to Predictive Failure. Normally when we replace a disk with Predictive Failure it will rebuild itself. It didn't happen this time. The disk led is green, anyone got any ideas?

Here are some details about the logical drive with the Predictive Failure physical drive.

Logical Drive: 2
Size: 273.4 GB
Fault Tolerance: RAID 1+0
Heads: 255

Array Accelerator: Enabled
Unique Identifier: 600508B100104D395355463239340003

physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 146 GB, Predictive Failure)
physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 146 GB, OK)
physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SAS, 146 GB, OK)
physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SAS, 146 GB, OK)

physicaldrive 1:3

Shalom,

Look at the front of the server. One of the disks in the array has probably got a yellow light. It is replacement time.

If not, it may be the disk controller and that will need to get looked at right away.

Ah sorry, I should have been more clear. The disk led is still green even after a disk replacement.

I'll probably need to take a look at the controller. Is there anyway to check the health of the controller?

hplog and hpasmcli both don't show anything weird.

hi,

you could contact HP, it could be some bug in the firmware ( disk / raid controller )
