I solved this issue by removing 'exclude kernel' config item from yum.conf. Because SAS raid driver limit, cannot use newer kernel, so excluded kernel update. removed 'exclude kernel' configure, it work fine for migrating from centos8 to rocky linux. But can not use newer kernel, must change grub to use old kernel otherwise no raid driver.
