There's always a, (* for lack of a better description, *) power pin with every drive and its seeded, male to female, at time of install. So powering up is automatic unless you flip the power switch on the bay, or array, or cabinet, etc. Sat, 15 Mar 2003 10:00:12 GMT Michael Steele_2 2003-03-15T10:00:12Z https://community.hpe.com/t5/disk-enclosures/spare-harddrives-in-an-array/m-p/2926801#M7833 simple question really, just never noticed. Does a spare drive in an array remain constantly powered up or is it powered up only when the array needs it? And, if a drive is not even a member of the array (compaq 531 array controller), does it remain powered up if it is not being used?<BR />thanks...
