How to display the HMC iqyylog.log

In this post I give you a hint how to display a log which is usually used by IBM support to identify a serious hardware error. Such information usually can be found in HMC log called iqyylog. Usually, when you get that kind of hardware error, you involve IBM support. Very likely, they will ask for PE debug data. There is a way how to display the log by yourself. Remember, such information is very technical. But maybe you find it useful.

  • First, you need to create the hscpe account on the HMC (if you haven’t done it). You can find the process here.
  • Log in to the HMC GUI under hscpe account.
  • In the Service Management menu you find three new options available

If you click on View Management Console Logs, you are going to see the log.

how to get ip address from hostname in CL (IBM i)

Today, I was preparing another program for automation. I need a function to retrieve an IP address of a remote system from the DNS having the system hostname. In the interactive session, you’d simple use ping or nslookup commands to resolve the hostname. But none of these commands can store the result into a variable. I did a short research, and there is very cool command Start DIG Query (DIG). This command can be used in a program, and it’s very easy get an IP address. Here is the example of a simple CL:
