131.0. "Problems disk booting" by ZYDECO::REDDY () Fri Jun 10 1994 22:15

    
We have a KAV30 customer who is having trouble booting from the SCSI disk.  They
are using a digital disk DSP3210 (it seems that this is very similar to RZ28).
When they boot from the disk, they get an error:  DKA0 failed - errorcode
000008C2.  If they downline load an ELN image, the disk is accessable and the
self test at >>> is successful.

I have had no problems disk booting, but I am using an RZ55.  Do we support the
disk this customer is using?  What does the error code mean?

Thanks,

Sumithra

131.1Check the ebuild fileEICMFG::CUSHNIEMon Jun 13 1994 15:2812
Hi Sumithra,

Check that the customer has the correct boot method selected in the 
System Characteristics menu in Ebuild, ie set to DISK.

If this is not the problem then the problem is probably the disk itself.

Hope this helps

Regards

John Cushnie@PCS.

    John,
    
    The boot method is "disk".  If ELN can access the disk, and read or
    write to it, should it not be able to also boot from it?  
    
    Any idea on what the error means?
    
    Thanks,

131.3%SYSTEM-E-FILESTRUCT...EICMFG::KAV30_SUPPMon Jun 13 1994 19:5321
    Sumithra,
    
    if you do 'exit 2242' (which is 8C2 hex) on a VMS machine, you get:
    
    %SYSTEM-E-FILESTRUCT unsupported file structure level
    
    (most ELN errors are the same as VMS...)
    Since the disk is accessible from ELN, the message is misleading. The
    only explanation we have so far is that the DSP3120 has a different
    timing behaviour than the rzxx disk we (and you) use. 
    
    Question: is the DSP3120 supported by ELN (latest version - we do not
    have the latest SPD/SSA...) ?
    If no, the customer should use a supported disk...
    If yes, we will investigate further where in the boot code the problem
    is...
    
    best regards,
    
    Thomas

    Thanks, Thomas.  I am waiting for the customer to come back from his
    vacation.  If I need any more help, I will get back to you.
