I am using IPMIView to remote control SYS-6016GT-TF-TM1 and my some keys on Japanese keyboard are not working. The OS in my SYS-6016GT-TF-TM1 is CentOS5.4 English version.
If the installed OS does not support Japanese keyboard, the Japanese keyboard will not be supported as well even if the remote side OS is Japanese version. It is not related to IPMI or IPMIView.
