You said you updated the microcode.
Do you mean the system firmware, or the device microcode?
Some devices like disks, adapters, CD drives, tape drives also have updatable microcode and it is a good idea to make sure all the embedded code is up to date before you attempt a software update / upgrade.
Bear in mind that software tends to be developed on the latest available firmware and microcode and some very strange things can happen if you try to run software on old system firmware or adapter / device microcode it has never been tested on.

Also when upgrading to 5.2 I would aim to go straight to a ML of as least 5, higher is better, say 8 or 9.

Hey guys,
since AIX 5.3 reaches EOS on april 2012, I really need to update my systems asap.
Any experience on upgrading directly to 7.1, with sap/db2/oracle?
could do fresh installs and import my sap/db vgs, but this would be a lot of work

I have a power5 that I would like to update and bring everything forward.
I am wondering about trouble-free upgrades. Is it better to go 5.3 -> 7 or 5.3 ->6 ->7?
The power5 box is behind and hopefully can learn from experiences here.
Thanks. (6 Replies)

IWN(4) BSD Kernel Interfaces Manual IWN(4)
NAME
iwn -- Intel Wireless WiFi Link 4965/1000/5000/5150/5300/6000/6050 IEEE 802.11n driver
SYNOPSIS
To compile this driver into the kernel, include the following lines in your kernel configuration file:
device iwn
device pci
device wlan
device firmware
You also need to select a firmware for your device. Choose one from:
device iwn4965fw
device iwn1000fw
device iwn5000fw
device iwn5150fw
device iwn6000fw
device iwn6050fw
Or you can use
device iwnfw
to include them all.
Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):
if_iwn_load="YES"
iwn4965fw_load="YES"
iwn1000fw_load="YES"
iwn5000fw_load="YES"
iwn5150fw_load="YES"
iwn6000fw_load="YES"
iwn6050fw_load="YES"
DESCRIPTION
The iwn driver provides support for Intel Wireless WiFi Link 4965, 1000, 5000 and 6000 series of PCI-Express network adapters. iwn supports
station, adhoc, and monitor mode operation. Only one virtual interface may be configured at any time. For more information on configuring
this device, see ifconfig(8).
This driver requires the firmware built with the iwnfw module to work.
EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
ifconfig wlan create wlandev iwn0 inet 192.168.0.20
netmask 0xffffff00
Join a specific BSS network with network name ``my_net'':
ifconfig wlan create wlandev iwn0 ssid my_net up
Join a specific BSS network with 64-bit WEP encryption:
ifconfig wlan create wlandev iwn0 ssid my_net
wepmode on wepkey 0x1234567890 weptxkey 1 up
Join a specific BSS network with 128-bit WEP encryption:
ifconfig wlan create wlandev iwn0 wlanmode adhoc ssid my_net
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
DIAGNOSTICS
iwn%d: device timeout The driver will reset the hardware. This should not happen.
iwn%d: firmware error The onboard microcontroller crashed for some reason. The driver will reset the hardware. This should not happen.
iwn%d: timeout waiting for firmware initialization to complete The onboard microcontroller failed to initialize in time. This should not
happen.
iwn%d: could not load firmware image '%s' The driver failed to load the firmware image using the firmware(9) subsystem. Verify the iwnfw(4)
firmware module is present.
iwn%d: could not load boot firmware An attempt to upload the boot firmware image to the onboard microcontroller failed. This should not
happen.
iwn%d: could not load microcode An attempt to upload the microcode image to the onboard microcontroller failed. This should not happen.
iwn%d: could not load main firmware An attempt to upload the main firmware image to the onboard microcontroller failed. This should not
happen.
