firmware for N4000

[vladimir_1]

Description of the latest FW 41.02 says it support CPU rev. 3.1. What does it mean? Because the system reports its FW as 40.4 and such CPU's seems to work fine. By the way who can say: does 40.4 mean 40.40 or 40.04 ?

And one more question. I used to upgraded firmware via bootable tape. For new servers it is in OS patch. When FW code is actually written in PDC hardware? Automatically after reboot?

Thanks

/usr/sbin/diag/contrib/pdcinfo
if you don't have it get PHSS_14982
or equivalent for your system.
This will give you info on your pdc revision.

I would imagine the pdc h/w is written to when the pdc tape upgrade says do not power off your server at this point....
PHSS_21679 allows online f/w update. That happens offline..

haven't heard of revision 40.4, but the 40.25 was released aug 2000 and 41.02 feb 2001

Later,
Bill

40.4 means 40.04

The latest PDC version for the N4000 is 41.02 which can be installed using patch PHSS_22657.
This patch WILL reboot the system.

When you apply firmware patch, system will be rebooted a couple of times.
After first reboot, you can see firmware downloading instead of normal boot procedure.
After this has done, the second reboot will take place which will bring the system up.

Please notice that you don't have to do anything while firmware is downloading.
Doing something can cause firmware corruption. Finally, failed to bring the system up.

Best regards,
