about A5597A(20/700) tape library CRC validation

[Jerry Chen_2]

My customer has a 20/700 library
I have upgrade it's firmware to 2.36(newest) at 12/14/2001
But the web screen from 20/700 show some error message at 1/29/2002
The message is :
The flash file system data does not pass CRC validation check(This happens most often when a firmware download has NOT completedsuccessfully ,retry the firmware download & reboot the machine)

I don't know what is CRC validation,and why this happened after one month that I upgrade the firmware.

Greetings ????????g

My question would be, what was the firmware version on the library BEFORE you upgraded ? There is a situation where you would have to perform the upgrade 2 times for it to succeed.

My next step would be to reflash the library again with code 2.36.

best regards,

I'll provide some more detail on reloading the firmware twice.

When going from pre-2.30 firmware to 2.30 or later, the following procedure should be done:

1) Load the 2.3X code once.
2) RESET THE LIBRARY so it will re-IPL. Use the reset button.
3) Reload the 2.3X code.

This should eliminate the 3D01 FSC error.
