RACADM
After performing an iDRAC reset (using the racadm racreset command), if any command is issued, the following
message is displayed. What does this indicate?
ERROR: Unable to connect to RAC at specified IP address
The message indicates that you must wait until the iDRAC completes the reset before issuing another command.
When using RACADM commands and subcommands, some errors are not clear.
You may see one or more of the following errors when using the RACADM commands:
Local RACADM error messages Problems such as syntax, typographical errors, and incorrect names.
Remote RACADM error messages Problems such as incorrect IP Address, incorrect user name, or incorrect password.
During a ping test to iDRAC, if the network mode is switched between Dedicated and Shared modes, there is no ping
response.
Clear the ARP table on your system.
Remote RACADM fails to connect to iDRAC from SUSE Linux Enterprise Server (SLES) 11 SP1.
Make sure that the official openssl and libopenssl versions are installed. Run the following command to install the RPM
packages:
rpm -ivh --force < filename >
where, filename is the openssl or libopenssl rpm package file.
For example:
rpm -ivh --force openssl-0.9.8h-30.22.21.1.x86_64.rpm
rpm -ivh --force libopenssl0_9_8-0.9.8h-30.22.21.1.x86_64.rpm
Why are the remote RACADM and web-based services unavailable after a property change?
It may take a while for the remote RACADM services and the Web-based interface to become available after the iDRAC web
server resets.
The iDRAC Web server is reset when:
The network configuration or network security properties are changed using the iDRAC web user interface.
The iDRAC.Webserver.HttpsPort property is changed, including when a racadm set -f <config file> changes it.
The racresetcfg command is used.
iDRAC is reset.
A new SSL server certificate is uploaded.
Why is an error message displayed if you try to delete a partition after creating it using local RACADM?
This occurs because the create partition operation is in-progress. However, the partition is deleted after sometime and a
message that the partition is deleted is displayed. If not, wait until the create partition operation is completed and then delete
the partition.
Permanently setting the default password to calvin
If your system shipped with a unique default iDRAC password but you want to set calvin as the default password, you must use
the jumpers available on the system board.
CAUTION:
Changing the jumper settings permanently changes the default password to
calvin.
You cannot revert
to the unique password even if you reset iDRAC to factory settings.
