I guess I don't understand how you expect smartctl to query a dead disk. It's
dead, that means it's not going to respond.
I secretly wished there was some kind of blackbox in some specialized chip or
memory
that specialized software can use for forensics and diagnosis.
A tool that queries the structure of the raid can tell you what drives the raid
expects to see, regardless of whether they are available or not[...]
[...] You can look for the (non-free) ssacli tool from HPE[...]
I figure that's the tool to query the structure of the RAID?
I can't find a 64bit version of it,
and the 32bit version isn't working well,
even after installing the 32bit versions of the glibc and libstdc++.
Here's an execution trace,
it gets stuck after showing a header line.
