Removing the HP-UX TCS Software
To remove (uninstall) HP-UX TCS A.01.00 from an HP-UX 11i v2 system, follow these steps:
1. Log in to the system as the root user.
2. Use the following command to remove HP-UX TCS A.01.00:
# swremove TCS
3. Use the swlist TCS command to verify HP-UX TCS was removed from the system. If
HP-UX TCS was removed from the system the swlist TCS command reports the following:
# swlist TCS
# Initializing...
# Contacting target ""...
ERROR: Software "TCS" was not found on ...
The HP-UX TCS software removal sequence includes the following operations:
1. The files in the /etc/opt/tcs/ directory are deleted. These files contain the TPM password
and the TCS encryption keys. Save these files to a location other than /etc/opt/tcs/
before removing HP-UX TCS if you want to preserve the content.
2. If HP-UX TCS is configured for EVFS, the removal script exits with an error and reminds
you to unconfigure HP-UX TCS for EVFS before removing HP-UX TCS.
3. The removal script stops tcsd, unloads the TPM device driver, and removes all product
file sets. Under normal circumstances you do not need to remove the product, unless there
is a TPM-related error affecting the system.
Clearing TPM Ownership
Clearing ownership causes the TPM to clear any existing secrets and delete the Storage Root Key
(SRK). Do not clear TPM ownership on HP-UX unless absolutely necessary (for example, if you
lose the TPM password). If you need to clear ownership, you must use the firmware shell to do
so. For instructions on clearing TPM ownership, see the HP-UX Trusted Computing Services Release
