Tools to test hdd

Unix itself is a toolbox and you can use the dd command.
Suppose you want to check disk: /dev/hdisk1
you can try this:
dd if=/dev/hdisk1 of=/dev/null bs=1k
Meaning read disk /dev/hdisk1 (block device) and write to /dev/null
To physically test the hard disk you can use the raw device name:
/dev/rhdisk1 or /dev/rdsk/c0t5d0 whatever special file you have.
So this would look like: dd if=/dev/rdsk/c0t5d0 of=/dev/null
The block size (bs) is optional.

There might be a SCSI test from your vendor.
Some SCSI controllers have built in tools.

fsck checks filesystems this is a different story.
vxfs (Veritas Filesystems) can do a replay using a intent log.
(fsck -o full in hp-ux forces a full check)

ufs checks the whole filesystem, all inodes.
check your man page for options.

Good luck with your SCS disk.
