Release Notes

Issues for Remote Access
NOTE: The Remote Access Service is supported on 11th generation of PowerEdge servers only. The following subsections list
the currently known issues regarding implementation and operation of your RAC and the Remote Access Service in Server
Administrator.
Issues of Server Administrator on all Operating Systems
• The Server Administrator user interface and commands related to local authentication enable are not applicable for RAC firmware
3.20. The Active Directory authentication feature replaces the local operating system authentication feature in this version of
firmware. Due to this change, the following commands return errors:
• racadm localauthenable
• omconfig rac authentication
NOTE:
The following packages will be deprecated from DellEMC Server Administrator current release (9.1.0):
1. Srvadmin-racadm4.
2. Srvadmin-racadm5.
• Due to fluctuations in the watchdog timer, the Last Crash Screen may not be captured when the Automatic System Recovery is set
to a value of less than 30 seconds. To ensure the correct functioning of the
Last Crash Screen feature, set the System Reset Timer
to at least 30 seconds.
• DF132894: The cfgDNSServer1 and cfgDNSServer2 properties of group cfgLanNetworking may be set to identical values while
swapping addresses. Some performance may be lost temporarily during the swapping. The cfgLanNetworking group is configured
using theracadm config command.
• The remote access controller uses FTP protocol to perform some of the Server Administrator commands. If a firewall is installed in the
system, it may cause these commands to fail.
The following Server Administrator CLI commands use FTP protocol to communicate with the RAC:
• omconfig rac uploadcert
• omconfig rac generatecert
The following racadm commands use FTP protocol to communicate with the RAC:
• racadm sslcertupload
• racadm sslcsrgen
• racadm fwupdate
• If the RAC configuration is reset to factory defaults using the racadm racresetcfg command, the RAC configuration tab in
Server Administrator does not reflect the reset configuration settings until the system reboots. Also, the RAC configuration page in
Server Administrator cannot be used to make any configuration changes until the system reboots.
• The RAC does not support local RAC user IDs with special characters. When adding a local RAC user, use only alphanumeric
characters for the user name.
• While the RAC is being reset, the Instrumentation Service cannot read sensor data for certain systems. As a result, the voltage,
temperature, and other probes may not be visible on the Server Administrator home page until the RAC has completed resetting.
• The RAC may not send traps when your system is locked up. To enable traps to be sent when the system is locked, configure the
watchdog timer using the Server Administrator GUI. On the GUI, click the "Properties" tab and ensure that
Auto Recovery is selected.
The default value of theAction On Hung Operating System Detection setting is None.None indicates that detection will not be
performed.
• RAC firmware 2.0 and later does not support passwords with special characters (non- alphanumeric) only for RAC user IDs logging in
using the Web-based interface (with Local RAC Authentication). You cannot log on to RAC, if you created RAC user IDs using
previous versions of the firmware or using Server Administrator that is running version 2.0 firmware on the managed system.
Use one of these methods to correct this issue:
• Change your passwords before updating the firmware.
• Use the following CLI command to change the password: omconfig rac users username=xx userpassword=yy where xx is the
original user ID and yy is the new password.
• Change the password through Server Administrator using the User tab. Make sure that the check box to change the password is
checked. Enter a new password, and then enter it again to validate the change.
• Use the racadm utility to change the password: racadm config -g cfgUserAdmin -o cfgUserAdminPassword -i <usr_index>
<new_pwd> where <usr_index> is the index of the user database entry to be modified and <new_pwd> is the new password.
