Verifying the Integrity of the CTM Installation ISO Image

Verifying the Integrity of the CTM Installation ISO Image

---

This appendix describes how to verify that the CTM installation ISO image is not corrupt.

---

Note The validity of the checksum does not guarantee the integrity of the ISO image. However, if the checksum is invalid, the ISO image is definitely corrupt.

---

---

Step 1 Copy the CTM ISO image to the local disk. The disk partition must have at least 2 gigabytes (GB) of disk space to store the CTM ISO image.

Step 2 Depending on your workstation type, complete one of the following substeps to generate the SHA-1 checksum:

a. On a Solaris server, enter the following command for the ISO image:

digest -a sha1 ISO-filename

b. On a Windows PC, use a tool such as the Microsoft File Checksum Integrity Verifier (FCIV) utility to generate the checksum for the ISO image.

For example, if you are using the FCIV utility, enter:

fciv.exe -sha1 ISO-filename

Note The FCIV utility is available on the Microsoft website at http://support.microsoft.com/kb/841290. This website is © 2010 Microsoft Corporation. All rights reserved.

Step 3 In the command output, verify that the checksum matches the value shown in the following table.
