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 rmware

3.20. The Active Directory authentication feature replaces the local operating system authentication feature in this version of

rmware. Due to this change, the following commands return errors:

– racadm localauthenable

– omcong rac authentication

NOTE: The following packages will be deprecated from DellEMC Server Administrator current release (9.1.0):

a Srvadmin-racadm4.

b Srvadmin-racadm5.

• Due to uctuations 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 congured using

theracadm cong command.

• The remote access controller uses FTP protocol to perform some of the Server Administrator commands. If a rewall 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:

– omcong rac uploadcert

– omcong rac generatecert

The following racadm commands use FTP protocol to communicate with the RAC:

– racadm sslcertupload

– racadm sslcsrgen

– racadm fwupdate

• If the RAC conguration is reset to factory defaults using the racadm racresetcfg command, the RAC conguration tab in Server

Administrator does not reect the reset conguration settings until the system reboots. Also, the RAC conguration page in Server

Administrator cannot be used to make any conguration 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, congure 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 rmware 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 rmware or using Server Administrator that is running version 2.0 rmware on the managed system.

Use one of these methods to correct this issue:

– Change your passwords before updating the rmware.
