I have 7038-6M2 server, its operating system is AIX 5.2, and its firmware is 3K041021
After some searching on net, I tried to update its firmware level to 3K080425, so I downloaded the required rpm, and followed the steps.
After rebooting the server, it stopped and an error code appeared on its LED, the error code is: E1F0
I rebooted it again, it stopped some minutes on the same error, then some green texts appeared then I choose to login into single user mode.
Then I rebooted it for the third time, but no response!!
It is standalone system, not connected to HMC, and not LPAR.
Now I have some updates, the server is running, not the problem in the Network! I can't ping, ssh, telnet it.
I checked its network configuration and it is correct!
