Never mind, this question has already been answered by Scott Weitzenkamp: You need to configure Device Mapper Multipath or some other multipathing software to get HA. What OS are you running?
Steps for RHEL are: 1) Edit /etc/multipath.conf and comment out devnode_blacklist (RHEL4) or blacklist (RHEL5) entry. 2) Run "chkconfig multipathd on". 3) Reboot. 4) After reboot, /dev/mapper should be populated with mutipath block device entries. 5) You can run "multipath -l" to view the multipath status. Steps for SLES10 are similar: 1) Run "chkconfig boot.multipath on". 2) Run "chkconfig multipathd on". 3) Reboot. 4) After reboot, /dev/mapper should be populated with mutipath block device entries. 5) You can run "multipath -l" to view the multipath status. You use the /dev/mapper block devices, not /dev/sd* block devices.
