The boot time of your system can increase dramatically if use Sun Cluster 3.2 in combination with Volume Management software. There is a bug 6626457 (boot time increases exponentially with S10U4 + VxVM 5.0 + Sun Cluster 3.2) which describe the issue in more details. Long boot times can be critical in the view of high availability.
Besure you have installed the following patch to decrease the boot time.
It's worth to install this patch anyway because the boot time also decrease if you running Sun Cluster without volume management software.
