[j-nsp] Booting from alternate media

[Javier Gallardo Córdova]

Hi,
   
  We had a M10 router without access from console port or telnet. As a remedy to get access, the router was turned off and on. After to do this, router boot fro alternate media (HD) instead of flash drive.
  There are two alarm presents:
  Alarm time               Class  Description
2005-11-22 17:58:11 CST  Major  compact-flash missing in Boot List
2005-11-22 17:58:08 CST  Minor  Boot from alternate media  
   
  Reviewing at messages lod, I find the next lines since more of ten days ago:
    Nov 9 21:15:44 MEXSJCTIJA /kernel: ad0: read interrupt arrived early
  Nov 9 21:15:44 MEXSJCTIJA /kernel: ad0: read error detected (too) late
  Nov 9 21:15:44 MEXSJCTIJA /kernel: ad0 removed from the Boot List
  Nov 9 21:15:45 MEXSJCTIJA alarmd[2293]: Alarm set: RE color=YELLOW, class=CHASSIS, reason=compact-flash drive error

  Nov 22 17:20:15 MEXSJCTIJA /kernel: ad0: not attached, missing in Boot List
   
  Do you know how can do extensive hardware tests over flash drive in order to diagnose if it have a uncorrectable  HW failure?. And, how reincorporate flash drive to boot list?.
   
  Thanks and regards.
