just this week we had an issue with bad disk (of the non-failing but 
disrupting everything kind) and issues with the raid controller (db of 
both controllers corrupted due to the one disk, controller reboot loops 
etc etc).

but tech support pulled it through, although it took a while. i'm amased 
what can be done with the hardware controllers (and i've seen my share 
of recoveries ;)

my question to ibm wrt gss would be: can we have a "demo" of gss 
recovering from eg a drawer failure (eg pull both sas connectors to the 
drawer itself). i like the gss we have and the data recovery for single 
disk failures, but i'm not sure how well it does with major component 
failures. the demo could be the steps support would take to get it 
running again (e.g. can gss recover from a drawer failure, assuming the 
disks are still ok ofcourse).
