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 correct functioning of the "Last Crash
Screen" feature, set the System Reset Timer to at least 30 seconds.
•
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 the "racadm config" command.[132894]
•
The remote access controller uses FTP protocol to perform some of the Dell OpenManage 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. In the Server Administrator GUI,
click the "Properties" tab and ensure that the "Auto Recovery" is selected. The default value of the "Action
On Hung Operating System Detection" setting is "None". "None" indicates that detection will not be
performed.
•
RAC firmware 2.0 and higher 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). If you created
RAC user IDs using previous versions of the firmware or if you created user IDs using Server Administrator
that is running version 2.0 firmware on the managed system, you cannot log in to the RAC.
Use one of these methods to correct this issue:
Change your passwords before updating the firmware.
OR
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.
OR
Change the password through Server Administrator using the "User" tab. Ensure that the check box to
change the password is checked. Enter a new password, and then enter it again to validate the change.
OR
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.
