How to view Firmware Levels

1. http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/topic/ipha5/viewexistlevel.htm
2. In V5R4M5 and above IBM added the command DSPFMWSTS. I still prefer using the HMC because the help on that at least explains what they mean.

What versions of HMC support which versions of firmware?

1. https://www14.software.ibm.com/webapp/set2/sas/f/power5cm/supportedcode.html
2. Determining if your server firmware level and HMC machine code level are compatible [1]

What versions of firmware are required for the various levels of i5/os?

1. V6R1 requires a minimum firmware level of SF240_332 for POWER5™ based systems and EA320_040, EL320_040, EM320_040 depending on the model for POWER6™ based systems. [2]
2. V5R4 requires a minimum firmware level of SF235_160. [3]

How do I obtain new levels of HMC code?

1. Through Fix Central at
   http://www-912.ibm.com/eserver/support/fixes/fixcentral
   selecting System i family and Hardware Management Console

How do I obtain new levels of firmware?

1. First, IMNSHO, you should have your system configured so that your firmware is HMC managed and not updated by upgrades to the OS of a particular lpar. This will help prevent you from getting a firmware upgrade so advanced that your HMC will no longer support it.
2. Through Fix Central at
   http://www-912.ibm.com/eserver/support/fixes/fixcentral
   selecting System i family and Server Firmware and Update policy set to HMC.

How do I configure an i5/OS lpar to be my service partition and apply firmware upgrades?

1. First, IMNSHO, you should have your system configured so that your firmware is HMC managed and not updated by upgrades to the OS of a particular lpar. This will help prevent you from getting a firmware upgrade so advanced that your HMC will no longer support it. Therefore I do not recommend configuring an i5/os lpar to be your service partition.

How do I access the ASMI?

1. http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/topic/iphby/accessasmi.htm

If I upgrade to V7 of HMC code what will the interface look like?

1. https://www-01.ibm.com/servers/resourcelink/lib03030.nsf/pagesByDocid/6DC24478DD66D14C852572E3005A70B3?OpenDocument

Is there a redbook on V7 of HMC code?

• PDF of Hardware Management Console V7 Handbook (sg247491) at IBM Redpieces

If I knew how to do something in V6 (or earlier) how do I do it in V7?

How to print a rack config from an HMC managed system

1. Printing Rack config information (see also "Printing I/O information")
   1. Signon to each i5/OS partition with an appropriate userid
   2. On a command line perform command STRSST
   3. Select option 1 Start a service tool
   4. Select option 7 Hardware service manager
   5. F6 to Print Configuration
   6. Take the defaults on Print Format Options (use 132 columns).
2. Printing I/O information
   1. Download a putty client
      (Sample - http://www.chiark.greenend.org.uk/~sgtatham/putty/)
   2. Set up the HMC for this.
      To enable SSH on the HMC you must do the following:
      • Start the ssh daemon:
      • Using the HMC system manager GUI, select HMC Management, then HMC Configuration. In the right-hand panel click on "enable or disable remote command execution". Verify the box is checked. Click ok.
      • Enable ssh in the firewall:
        • Using the HMC system manager GUI, select HMC Management, then HMC Configuration.
          • In the right-hand panel click on "Customize Network Settings".
          • In the "Customize Network Settings" dialog click the "Lan Adapter" tab,
          • select the lan adapter connected to your network (usually eth1), click the "Details" button.
          • On the Details panel, click the Firewall tab.
          • In the top list box click "Secure Shell 22:tcp".
          • Click the "Allow Incoming" button.
          • CLick ok on each panel to exit.
          • It will tell you that you must reboot but this is not necessary. Firewall settings go into affect immediately.
      • Now in putty, verify you used the ssh protocol. Say yes when it gives you a security warning.
      • If you still have problems verify that you can ping your HMC. Verify that any firewall between you and the HMC allows port 22.
        
   3. Start your putty client to your HMC. Use the same userid's and password you normally use to log on to your HMC. (hint: A default user id is hscroot. A default password may be abc123)
   4. Enter the first command to get a list of systems managed by this HMC:
      • lssyscfg -r sys -F name
      • Take a name from that list and put it in the double quotes instead of sysname:
      • lshwres -r io --rsubtype slot -m "sysname" -F unit_phys_loc,bus_id,phys_loc,vpd_type,description,lpar_name
   5. From your putty client, Copy all to Clipboard. Paste that into your favorite tool like Word, Excel, etc.

1. An alternative would be to use the System Plan functionality supplied with the HMC v7

How do I do a screen print of a HMC screen

Document Number: 358236751

Document Title: [5] Capturing Screen Shots from the HMC

• Imagemagick (Open Source) as recommended in the Document is useful to view the files.
• I found HMCWIN in a one line window, and Sendfile to send to the IFS simplest to use, but I think a PuTTY client may be easiest.
