1.    Log in again selecting the Log In option of "Classic".
2.    If already logged in to the HMC using Enhanced GUI, log off the HMC.
3.    Install using the normal installation instructions.

Alternatively, install this PTF using the CLI updhmc command.

2. After applying Service pack 3, discard any older backups and take a new backup. When taking a backup, specify the current fix level (lshmc -V output) in the backup description field to help identify the fix level the backup was taken from. Before restoring a backup, apply the same fix level (service pack and iFix) that the backup was taken on. If this is not followed the restore may produce unpredictable results.

3. This PTF is no longer available for download or order.
The following problems occur after installing PTF MH01677:

Custom HMC users are unable to log in to the HMC GUI and receive "Console Internal Error. Details: HTTP status code: 500 The server encountered an internal error that prevented it from fulfilling this request." The user can log in via ssh however attempting to run most commands fails with "HSCL8016 An unknown error occurred while trying to perform this command. Retry the command. If the error persists, contact your software support representative."
All custom users lose their task role assignment and any custom managed resource role assignment. Users hscroot, root, and hscpe (if created) are not impacted.
One or more custom task roles may be deleted.

List of fixes

Security Fix

Fixed Apache Tomcat vulnerabilities CVE-2016-6816, CVE-2016-6817 and CVE-2016-0762
Enabled TLSv1.2 on HMC port 12443 when HMC is in Legacy mode.
Removed support for all Triple DES ciphers from the Web UI (HMC ports 443 and 12443) to address vulnerability: CVE-2016-2183

General fixes

Fixed a problem causing a blank window to be opened when the ASM interface for a server is launched when the server is in Failed Authentication state.
Fixed an issue where HMC performance degrades over time until the command server and/or web servers hang requiring a reboot to resolve. Logs will show a large number of blocked threads for the unified JRE and may include an error of "too many open files". The issue is typically seen on HMCs where external scripts are running dozens or hundreds of commands.
Fixed a problem that caused the lpar_netboot command to fail with the error "The system has no more ptys. Ask your system administrator to create more."

Additional information

Notes:

The Install Corrective Service task now allows you to install corrective service updates from the ISO image files of these updates. You can download these ISO image files for the HMC, and then use the ISO image file to install the corrective service update. You no longer need to burn CD-R or DVD-R media to use the ISO image file to install corrective service.
This image requires DVD -R media.
To install updates over the network, select the *.iso file on the "Select Service Package" panel of the Install Corrective Service task. The HMC application extracts the files needed to install the corrective service. If you are using USB flash media, copy the *.iso file to the flash media, and then select the file when prompted.
The updhmc command line command has also been modified to use the *.iso file. To use the command, follow the syntax in this example:
updhmc -t s -h <myservername> -f </home/updates/corrrective_service.iso> -u <HMC_username> -i

In all cases, the HMC application extracts the files needed to install the corrective service.
