Such a tool does not exist. Every disk that cannot be identified by AIX is recognised as Other SCSI disk (osdisk) usually. You can use it, no sweat, but you are unlikely to use it with adequate settings. Therefore the disk will be slower than it could be. Some vendors offer special drivers for AIX or at least some ODM entries to facilitate use of their disks by AIX. If you cannot get such type of support you need to find a datasheet for those disks. E.g. with the information about queueing type and queue depth you can configure OEM SCSI disks manually. However to find out what disk it is you probably need to take it off the machine and look at the label.

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.
