hoff, the physical volume /dev/dsk/c5t6d0 was added to volume group vg01. Possibly other disks might have been added to vg01 as well. Then vg01 is carved up into logical volumes such as /dev/vg01/lvol4. And then file systems were created on the logical volumes. It is possible to ignore LVM and install a file system directly on a physical disk, but few people would do that and the OS installation procedure would make it rather hard to do. So, yes, you need to fsck /dev/vg01/lvol4 and lvol5.
