• Known Issues
• Installation

• Added additional call home logging for SRC E212E161 when too many open files are detected on the HMC.
  
• System and partition description fields are now restricted to ASCII characters only.  If you have an existing system or partition description that contains non-ASCII characters, please update it to contain only ASCII characters.  On FSP-based systems, a non-ASCII character in a system or partition description field can cause the display of system settings or partition properties on the GUI to fail with an error.  On eBMC-based systems, a non-ASCII character in a system or partition description field can cause the system to transition into Recovery state and after recovered to transition into Recovery state on the other HMC in a dual HMC environment.
  
• Added a workaround to prevent the Firefox browser on the local HMC console from attempting to connect to Google addresses such as "201.181.244.35.bc.googleusercontent.com".  The workaround is to disable DNS in Firefox.  To disable DNS in Firefox and relaunch the Firefox browser on the local console, log in as user hscpe with role hmcpe and run "runsig -s 711" in the restricted shell.  To reenable DNS in Firefox and relaunch the Firefox browser on the local console, log in as user hscpe with role hmcpe and run "runsig -s 712".
  
• Fixed an issue causing the asmmenu command to always fail to launch the ASM menu window and the following Firefox error to pop up instead: "Firefox is already running but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

• Fixed vulnerability: CVE-2023-38280. Removed support for all sed command options in the restricted shell.

• Incorrect values are shown in the Storage I/O usage column on the Usage page of the Systems and Partitions tables in the new GUI dashboard.
  
• If log in to the HMC GUI is failing with this error for LDAP or auto-managed users: Error: "Logon Error: Invalid credential or Timeout. Please try again after some time, if it repeats, please follow troubleshooting steps from IBM support."
  Use the following troubleshooting steps:
  • Check whether the user is LDAP or auto-managed authentication type.
    
  • If so, run the following command to change the LDAP configuration:
    chhmcldap -o s --timelimit 30 --bindtimelimit 20
  • If log in to the GUI still fails, run the following command:
    chhmcldap -o s --timelimit 30 --bindtimelimit 10
