[gPXE] Why disk not appear in the disk management tool?

[KernSafe Technology]

Hi Shao Miller,

 

They are two conditions:

 

1, Local hard (only one) drive boot, without keep-san, just do a sanboot, it will register and unregister int13 drive, and then boot from local hard drive, no disk appear in disk management.

2, remote boot (only one san disk, with out harddisk), with keep-san 1, boot from san, no disk appear in disk management tool.


>How does "original local drive lost" mean "it will boot from my harddrive"? 

Yes, it will boot from hardrive just like a normal boot, but you can't see disk in disk management tool.

 

If needed, I can send you my test tools.

 

Aldrich.

Hi,
 
Yes, I mentioned because I just for a test, when a SAN drive registered and then unregistered, the original local drive lost, so I think it is the reason.

But you just wrote in your last e-mail:


Then I type exit to exit gpxe command line, it will boot from my harddrive, after booted, I opened computer management console, I can't see a hard disk (only on local hard disk).

How does "original local drive lost" mean "it will boot from my harddrive"?


But when there is no local disk, I used
set keep-san 1 to boot from a SAN, the drive can't be seen still (keep-san 0 also has this problem). It is difficult to understand.
Is the problem might be caused by int13 drive change?
If you see "Unregistering BIOS drive 0x80", that means that gPXE did hook INT 13h, but then unhooked it.  If you 'set keep-san 1' _before_ the 'sanboot', you should not see this message.  If you see the message, that means that keep-san was not set to 1.  If you correctly 'set keep-san 1' _before_ the 'sanboot', you will see this message:

"Preserving connection to SAN disk"
