[smartmontools-support] DEFAULT -n standby not working for Adaptec Raid

Oh!  

Hmmm... Can I configure smartd so that the -a stuff and the temperature
check are only done (e.g.) once every 24hrs or so (maybe with a retry after
a couple on mins if they fail because the device is powered off)?

Thanks again
David

If the controller firmware spins down the drive, it may later spin up 
the drive before the next command is issued. A workaround would require 
a separate I/O-control which reports the power state before a 
pass-through command is issued. This would require a specification from 
Adaptec or some sample source code.

Note that '-n standby' for SCSI/SAS drives is only implemented in 
smartctl, but not yet in smartd.

Thanks,
Christian
