Smart Array 642 Controller on HP ML350-G4 - continuous auto rebuild !!

Deal all,

we had a disk crash in our HP ML 350-G4.

We have replace the faulty one with a bigger 72GB disk, instead the previous ones of 32GB.

After the reboot it promts for autorecovery, but it does it pretty quick, in 30-40 secs.

Thru Smart array conf utility the logical drive it is on state ready for recovery.

After many reboots nothing chages, it always performs a very quick autorecovery and the status is always on ready for recovery.

i am attaching also the report fro smart array diagnostics.

 

Please advice

Thank you in advance.

Hi,

 

seems from decoding the SCSI sense keys in the report file that disk 2 and 3 have a status of "Read retries exhausted" , so basically we get read failures while rebuidling/reconstruct the raid5 data onto disk 0 (the new disk of 73 GB) so the rebuild stops.

 

 

So , in short you can only recover from this by backup the data and reinstall the array from scratch. But maybe it would be a good time to get 3 or 4 new disks now because the read errors on disk 2 and 3 could come back later ....

 

 

HTH
