This chapter contains information about OpenBoot PROM features that support Sun Remote System Control.
Several new OBP commands have been added to support RSC. You enter these commands at the ok prompt.
Performs a hard reset of RSC; this is the same as using the command rscadm resetrsc.
Performs a soft reset of RSC; this is the same as using the command rscadm resetrsc -s.
Directs POST output to either RSC (1) or ttya (0). This command takes effect after the next server reset.
Updates the RSC Ethernet address from the contents of the server ID PROM. Use this command after replacing the server NVRAM module.
Displays RSC information, including the diag-output-to setting and the RSC POST status word.
Two environment variable properties are available to the user for specifying the RSC console to OBP. Define these variables at the ok prompt. For example:
ok setenv input-device rsc
These properties take effect after the next server reset.
This property is a new device alias that is valid for ttyio, input-device, and output-device OBP console variables. Screen output and keyboard input are typically still set to be the default, and ttya and ttyb continue to be other valid options.
This property is a new device alias that is valid for ttyio, input-device, and output-device OBP console variables. Screen output and keyboard input are typically still set to be the default, and ttya and ttyb continue to be other valid options. This variable does not allow OBP to autosearch for a working console if RSC is broken.
