Wiping a disk is probably better done on the disk level, not the filesystem level. Write some stuff (random, just zeroes or just ones) at the disk device instead of the mount point.
If you still want to go with your procedure you can use the "mount" command to find out where the filesystems are mounted. It always looks a little different from system to system, so there is no general line i could give you, but surely you can figure out some parsing schema once you see it. A simple way to read a tablelike output would be (replace "<b>" and "<t>" with literal blanks/tabs when you write it):

hello,
We are using Solaris 11.3 on SPARC T5-2. The below is the actual output from "zpool status" command. The disks were scrubed last week, but it says the scrub repaired on Dec 31, 1969.
Does anyone know how to correct this to report the correct date?
Thanks

hformat
HFORMAT(1) General Commands Manual HFORMAT(1)NAME
hformat - create a new HFS filesystem and make it current
SYNOPSIS
hformat [-f] [-l label] destination-path [partition-no]
DESCRIPTION
hformat is used to write a new HFS filesystem to a volume. A UNIX pathname to the volume's destination must be specified. The destination
may be either a block device or a regular file, but it must already exist and be writable.
An optional label can be specified to name the volume. The name must be between 1-27 characters and cannot contain a colon (:). By default,
the volume will be named Untitled.
If the destination medium is partitioned, one partition must be selected to receive the filesystem. If there is only one HFS partition on
the medium, it will be selected by default. Otherwise, the desired partition number must be specified (as the ordinal nth HFS partition) on
the command-line. The size of the partition determines the size of the resulting volume.
Partition number 0 can be specified to format the entire medium as a single filesystem without a partition map, erasing any existing parti-
tion information. Since this will destroy all the partitions, the -f option must be specified to force this operation if the medium cur-
rently contains a partition map.
If the medium is not partitioned (or if partition 0 is specified), the size or capacity of the medium determines the size of the resulting
volume.
The new volume will be empty and will become "current" so subsequent commands will refer to it. The current working directory for the vol-
ume is set to the root of the volume.
EXAMPLES
% hformat /dev/fd0
If a floppy disk is available as /dev/fd0, this formats the disk as an HFS volume named Untitled. (N.B. The floppy must already
have received a low-level format by other means.)
% dd if=/dev/zero of=disk.hfs bs=1k count=800
% hformat -l "Test Disk" disk.hfs
This sequence creates an 800K HFS volume image in the file disk.hfs in the current directory, and names it Test Disk.
% hformat -l "Loma Prieta" /dev/sd2 1
If a SCSI disk is available as /dev/sd2, this initializes the first HFS partition on the disk (which must already exist) with a new
filesystem, naming the resulting volume Loma Prieta.
% hformat -f /dev/sd2 0
This causes the medium accessible as /dev/sd2 to be reformatted as a single HFS volume, ignoring and erasing any existing partition
information on the medium. The -f option must be specified if the medium is currently partitioned; otherwise the command will fail.
NOTES
This command does not create or alter partition maps, although it can erase them (as described above). Any partition number specified on
the command line must already exist.
The smallest volume size which can be formatted with hformat is 800K.
