Hello All,

maybe somebody can help. I’m very new to Cobalt units and honestly speaking, to Linux too. At eBay I bought a VelociRaptor 1100 (unfortunately without the Management Console CDROM) and unable to get out of this box something useful. The last I was told, is that the box has been reset to “factory defaults”. But it looks like there is a part of the boot sequence removed.

First I’m unable to get  the serial console to work – the automatic baudrate recognition sees nothing, the only output I’m getting is when setting  the configuration to 9600-8-N-1, but the result is not human readable (only some fancy characters).
Other combinations don’t bring any result at all – could somebody tell me, what the factory default setting should be? The “Implementation Guide” at http://seer.entsupport.symantec.com/docs/notes/manuals/sym_velociraptor/sym_vr_15_other_models/vr15_implementation.pdf.html says 155.200 bps – but this combination does not work.

What combination between “S” – “configure boot disk” and “loading from  ...” should be used by default?  The longest sequence (“Starting System” -> “Loading Kernel” -> “Booting” -> “Symantec Corporation” -> “Symantec Gateway Starting”) I’m getting when using “hda1” and “disk”. But thereafter nothing happens – I’m unable to reach a menu with the buttons, neither something else. All other combination don’t make more sense –sometimes the system hangs with “Loading Kernel”,  other combinations create an endless  “Starting System” -> “Loading Kernel” sequence.

A CMOS restore with “E” doesn’t help – I’m still unable reach something useful.

The ROM is unchanged – does it make any sense to put the drive out of the unit and give them a new image, so that I could at least boot a system, flash the ROM with ext3 and try to install the RaqCop Distribution? I tried to google to find something useful, but fizzled out. Any recommendations would be highly welcome – I’m lost in space.

When trying different boot scenarios the network interfaces are always silent, there is nothing sent out. When trying to “boot from network“ I can see the boot broadcast requests (sent to 255.255.255.255 port 67) – but unable to offer something useful to the appliance. Does somebody know where to find a boot image for a Symantec VelociRaptor, Restore CDROM or something else, which could help?

And one last question – is there any other chance to reset the appliance, except the “E” when power on?

Sorry for the long post and thank you in advance, Rainulf.

 Your VR1100 is a 3000 series Cobalt so no problem there. The baud rate is hard coded at 115200 by way of the rom. It has to be a nullmodem cable, not a standard serial cable. You can't run anything new with the old rom image that you have unless both the kernel and driver modules are in the same partition and even then an ext3 filesystem will be mounted as ext2.

Hello Dave,

thank you for the hint with the nullmodem cable, I only checked that pins 2/ 3 are crossed and 5 is the common ground, now I see that the pins 1/ 4 are not crossed. http://www.nullmodem.com/NullModem.htm

Concerning the hanging startup sequence I’ve got an idea - a forensic show a fresh core dump, each time the appliance restarts. Let’s see, may be I’ll manage to get a console access.

Regards, Rainulf.
