I have a Linux Rackmount server with  4 disks in a SATA RAID 5 array managed by a 3ware controller and want to add another disk in standby mode, so that if any of the 4 disks fails, the standby will take over. Is it sufficient just to plug in the disk and have it in READY mode (as seen on the 3ware console mode), or some other action has to be taken?

You need to designate it a "hot Spare"

You can download the manual here: http://www.3ware.com/support/UserDocs/EscaladeUG7000-122003.pdf
Page 101 talks about specifying the hot spare.
