Known Issues
#####################################################################
* In a BMC-only server, the tool is slow when compared to DRAC in 9G. This is
because the same channel is shared by both the console redirected data and
Windows debug data. Also, to establish WinDbg session, you must set the BIOS to
Serial Communication: On with console Redirection through COM2.
Due to the slow connection, there is no support for 9G BMC.
* DWDU does not debug 8G Servers. This is because; 8G supports IPMI1.5 that
supports only lan interface. The IPMItool is designed to work with lanplus interface
to establish SOL connection that DWDU uses. Therefore, there is no support for 8G.
* Sometimes, there are issues when establishing/disconnecting DWDU sessions.
This is because, after you stop DWDU connection, it sometimes takes longer for the
DRAC SOL channel to completely end. During such conditions, try reconnecting
after 3-4 minutes.
* DWDU connection is established only once with iDRAC for blade servers (10G/11G).
This is because, once the SOL connection is established, you cannot end it.
To end it, you must enable the SOL in DRAC to reset the iDRAC for blade servers.
* Active Directory login is not supported using DWDU. This tool works only with
DRAC user name or IP address.
