Cascade Failure - 4SI RAID

rmueller58 — Fri, 09 Jan 2009 13:48:59 GMT

2nd Day in a row I've have a problem with RAID

Yesterday it appeared to begin on 1:0 and 1:1 today it appears to have started on 1:9, Any thoughts on what to look at 1st.

The configuration is an SC10 8 disk set, with a RAID 4SI card.

in discussions it could be another disk in the set, the chassis backplane of the SC10 or the RAID card.. Any thoughts as to what to look at 1st.

HP's FE is dispatched and on his way over to the shop, wanted to see if anyone has experienced the multiple cascade failure and the best avenue to fix and correct it..

Problem related to backplane on SC10, FE replaced backplane and cascade failure ceased.
