failed to boot

[ERY JP]

Hi,
My DS10 crashed but ussually it automatically restart, so it will be normal again. But lately when it crashed it failed to restart automatically. The error message is:

failed to open dkb0.0.0.17.0

or

device dkb0.0.0.17.0 no longer valid
bss = 1294608
Starting at 0xfffffc00004b3dd0
halted CPU0
halt code=2
kernel stack not valid halt
PC=4
boot failure
>>>

sh dev show that dkb0.0.0.17.0 is unavailable. But after I press the Halt/reset, sh dev show that dkb0.0.0.17.0 is available again. Then I can boot normally. My question is: Why device dkb become unavailable on the first time? How to solve this situation?How to know why the DS10 suddenly restart? Hope someone could help me.

My guess is that the faulty disk caused the crash. Fresh system initialization seem to be successful, but the disk problem could still persist at some point.

The crash files under /var/adm/crash directory should have some info.

Also, check the syslog files and the binary.log file.

The disk may be having problems, maybe is about to fail or there is a problem with the cable connections. Also, maybe the power supply is not providing the neccesary power to the disk. Use the show power SRM command to verify the status of the power supply.

Can you try to change the SRM setting?
boot_reset = ON

Thanks everybody. Seems the problem is on the hard disk. I already replace it and restore my backup.
