Sun SC Cannot believe it has turned the system power on...
Dear Hicks,
Downloaded all the manuals about Netra, ALOM, etc. Very superficial, lightly touches on things. But still explained a few points like the DB9 serial port. That indeed was not intended to help with ALOM access. Just a regular serial port for after the OS boots, not a management port at all.
Now as I wrote I can start the leaf blower fan inside with just a "poweron" command. To start individual sub-components (FRUs), I tried " poweron {fru} " commands. For motherboard ı tried "poweron MB", "poweron MOTHERBOARD", and "poweron MB.SEEPROM", for SCSI disks I tried "poweron SCSI", "poweron ENC", "poweron ENC.SEEPROM", does not like these names, declares invalid. When I try "poweron PS1", or "removefru PS1", the SC does NOT declare these name are invalid but says they are NOT present!
Now this is fun indeed! ıf we have no Power Supplies present how the heck are we talking to you Mr. SC?
In summary I need to supply power to the DVD drive to boot anything. I looked inside the DVD bay, there indeed seems to be socket there intact. Since the HDD power light comes on and goes out, I think we just need the correct FRU name for the SCSI subsystem.

bootparams
BOOTPARAMS(5) BSD File Formats Manual BOOTPARAMS(5) NAME
bootparams -- boot parameter database SYNOPSIS
/etc/bootparams DESCRIPTION
The bootparams file specifies the boot parameters that diskless(8) clients may request when booting over the network. Each client supported by this server must have an entry in the bootparams file containing the servers and pathnames for its root, area. It may optionally contain swap, dump, and other entry types. Each line in the file (other than comment lines that begin with a #) specifies the client name followed by the pathnames that the client may request by their logical names. Names are matched in a case-insensitive fashion, and may also be wildcarded using shell-style globbing char- acters. The components of the line are delimited with blank or tab, and may be continued onto multiple lines with a backslash. For example: dummy root=server:/export/dummy/root swap=server:/export/dummy/swap dump=server:/export/dummy/swap gateway=router:255.255.255.0 When the client named "dummy" requests the pathname for its logical "root" it will be given server ``server'' and pathname ``/export/dummy/root'' as the response to its RPC request. netra[1-5]www* root=server:/export/jumpstart/netra_www When any client with a name matching the pattern "netra[1-5]www*" requests the pathname for its logical "root" it will be given server ``server'' and pathname ``/export/jumpstart/netra_www'' as the response to its RPC request. As this example implies, this is useful for set- ting up Jumpstart servers for Sun clients. NOTES
The server does not default to the localhost, and must be filled in. FILES
