I have an external dock with a couple of SATA HDDs in it, which is
normally spun down. The drives are RAID-1 but you can ignore that. To
spin it up I do:
SLOT1=/dev/disk/by-id/wwn-0x50014ee058f952e1 # Usually /dev/sdd
SLOT2=/dev/disk/by-id/wwn-0x50014ee212458648 # Usually /dev/sde
spunup() { # At least one is spun up, so RAID should work
if sudo hdparm -C $SLOT1 $SLOT2 |grep -q active/idle ; then
return 0
else
return 1
fi
}
spinup() {
sudo hdparm $SLOT1 $SLOT2 >> /dev/null 2>&1
for t in 1 2 ; do # Make sure it's up
spunup && return
sleep 5
done
}
poc
