3. Remove the current TCS software by entering the following command:
swremove TCS
4. Download the new version of TCS software, as described in “Step 2: Acquiring TCS Software”
(page 23).
5. Use swinstall to install the software, with deferred configuration. This procedure is
described in “Step 3: Installing TCS Software” (page 23) and “Deferring TCS Configuration”
(page 24).
6. If necessary, restore the backup copies of the /etc/opt/tcs/passwd and /etc/opt/
tcs/system.data files. For information about file permissions, owner, and group
information, see “Restoring TCS System Data” (page 30).
7. Reconfigure the TCS software by entering the following command:
swconfig TCS
8. Verify the TCS installation by entering the following command:
swverify TCS
For more information, see “Step 4: Verifying the TCS Installation ” (page 24).
9. Verify TCS operation by entering the following command:
tcslist status
For more information, see “Step 5: Verifying TCS Operation” (page 24).
Removing TCS
Under normal circumstances you do not need to remove the TCS bundle unless there is a
TPM-related error affecting the system.
CAUTION: Removing the TCS bundle deletes the TPM password and all TPM keys stored in
system persistent storage. Any data encrypted with or using TPM keys becomes unusable if you
do not create a TPM key archive as described in “Creating and Restoring TPM Key Backup Files”
(page 31).
To remove TCS, follow these steps:
1. Log in to the system as a superuser.
2. Prepare to remove the TCS software bundle as described in step 2 in the procedure
“Upgrading or Reinstalling TCS” (page 25). If you want to retain data in the /etc/opt/
tcs/ directory, move the data to another location.
3. To remove the TCS software bundle, enter the following command:
swremove TCS
4. To verify TCS was removed from the system, enter the following command:
swlist TCS
If TCS was removed from the system, the swlist TCS command displays the following
messages:
# Initializing...
# Contacting target ""...
ERROR: Software "TCS" was not found on ...
The TCS software removal sequence includes the following operations:
