I think you should be able to verify the disk surface from within format and there is an option to do a destructive test. There was certainly one to do a non-destructive test when I used to have a Solaris server.
Is that an option? An alternate would be to slice the disk differently and then install a default Solaris and create filesystems from the other slices. That would probably clobber most data pointers.
Of course if you are super paranoid or have a regulatory or contractual obligation then you can remove and destroy the disks with a degausser (not sure on cost) or with one of the recycle companies that turn it all into high mineral compost.
What level of certainty do you need that no-one can read your data? A drill through the casing is a pretty good deterrent over data recovery.

diskscan
diskscan(1M) System Administration Commands diskscan(1M)
NAME
diskscan - perform surface analysis
SYNOPSIS
diskscan [-W] [-n] [-y] raw_device
DESCRIPTION
diskscan is used by the system administrator to perform surface analysis on a portion of a hard disk. The disk portion may be a raw parti-
tion or slice; it is identified using its raw device name. By default, the specified portion of the disk is read (non-destructive) and
errors reported on standard error. In addition, a progress report is printed on standard out. The list of bad blocks should be saved in a
file and later fed into addbadsec(1M), which will remap them.
OPTIONS
The following options are supported:
-n Causes diskscan to suppress linefeeds when printing progress information on standard out.
-W Causes diskscan to perform write and read surface analysis. This type of surface analysis is destructive and should be invoked
with caution.
-y Causes diskscan to suppress the warning regarding destruction of existing data that is issued when -W is used.
OPERANDS
The following operands are supported:
raw_device The address of the disk drive (see FILES).
FILES
The raw device should be /dev/rdsk/c?[t?]d?[ps]?. See disks(1M) for an explanation of SCSI and IDE device naming conventions.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Architecture |x86 |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
SEE ALSO
addbadsec(1M), disks(1M), fdisk(1M), fmthard(1M), format(1M), attributes(5)
NOTES
The format(1M) utility is available to format, label, analyze, and repair SCSI disks. This utility is included with the diskscan, addbad-
sec(1M), fdisk(1M), and fmthard(1M) commands available for x86. To format an IDE disk, use the DOS format utility; however, to label, ana-
lyze, or repair IDE disks on x86 systems, use the Solaris format(1M) utility.
