is the only way to get back all the data on my sata raid array (striped) to have it hooked up to the exact same raid chip? -sil3112 on ga-8knxp that just died
You need the same stripe settings, too. Some mfgs provide utilities that can reinitialize stripesets without blowing them away, but to my knowledge Sil is not one of them.
To be frank, you're going to be a guinea pig. Sometimes it works, sometimes not. I can't tell you for certain unless I try it myself with the exact same setup. The el-cheapo raid adapters are flaky at best.
