Key Mappings for the HMC 5250 Console

The HMC 5250 console function uses the 5250 emulator from the IBM iSeries Access for Linux product. Emulator documentation is available on the HMC by using the Help menu option on the emulator or the setup panel.

Control Functions

Control functions are available from the 5250 emulation session Control menu. To send a control key, click the Control menu, then select any of the following keys:

Reset key

System Request Key (SysRq, also commonly known at the sysreq key)

Attention Key

Help Key

Enter Key

The control functions can also be accessed by using a key sequence.

Default Key Sequences

The default key sequences can be viewed by clicking the Help menu and selecting the Key Sequences topic. The current keyboard mappings can also be viewed by clicking on Option > Keyboard Remapping. Some examples follow:

Attention: Esc

Copy to clipboard: Shift + left-click (click and drag to select, release to copy)

Paste from clipboard: Shift + right-click

Note: On the HMC, the Print Screen, Scroll Lock and Pause/Break keys are reserved for the window manager. All default mappings using those keys are disabled. This includes the default mapping for the System Request Key (Alt+Print Screen).

Keyboard Remapping

The 5250 emulator keyboard mapping can be customized. To change or view the current mappings, do the following:

1. Start a 5250 emulation session.

2. Click on the menu item Option > Keyboard Remappings. If the menu item is missing or disabled (grayed out) then verify that it is enabled in the IBM 5250 Setup panel. The setup panel can be launched by doing the following:

a Right-click on the desktop and select Terminals > IBM5250.

b In the 5250 Setup panel, click Preferences > 5250.

c Verify the keyboard mapping setting is enabled.

3. The Keyboard Remappings panel can be used to change the default mappings. For example, the system request can be mapped to Shift + Print Screen.

4. Click the Apply changes to session button to apply the changes to the current emulation session.

5. Click the Save button to save the changes. The user can select to save the changes as the new mapping for all user sessions or for this emulation session only. The changes are scoped to the current HMC user profile.

Using Other Emulators

The HMC remote 5250 console function allows other emulators to be used. If a user has already created customized macros, keypads, keyboard mappings, and so on for another emulator, it might be easier to use that emulator over a remote 5250 console than to re-create the customization on the HMC.

SRC A9002000 on an HMC-Managed System after Installing from a SAVSYS

A restore was completed from a V5R1 system to a new Model 570 at V5R3 following the procedure for a slip migrate release. At the point where the users were ready to do a B-IPL, they could not access the system console, which was a HMC console. They received an SRCA9002000, which indicates the system console cannot be found. A manual B-IPL works fine through DST and locates the console.

The problem was with the old controller type that was brought over with the restore from the V5R1 system. WRKCTLD showed controllers, but these were brought over from a V5R1 configuration. They did not work because the controllers used for an HMC console are of a different type. There was a 2746 Twinax CTLD varied on with no device under it. They had 5 CTL0x twinax controllers.

To resolve the problem, vary off all old CTLDs from the V5R1 system and turn on QAUTOCFG. After the normal IPL starts, it will autoconfigure a CTLD for the HMC console that is the correct type, and the console will have a sign on screen.

HMC 5250 Console Disconnects After a Period of Inactivity

Problem

After upgrading to HMC V4R2.1_0902, the HMC 5250 console can disconnect from a partition after 2 hours of inactivity. If the partition is running IBM® i5/OS™ with MF33488 or later, the console returns to the DST sign on screen. The user will see the 'resume' screen after logging back in. For earlier levels of i5/OS, the console session is lost. If the user attempts to reconnect, the console will hang with the message "0043 Connected - waiting for screen data".

Recovery

For i5/OS levels before MF33488, the only recovery is to IPL the partition.

To prevent the console hang problem from recurring until an e-fix is available, connect with a shared console or apply MF33488 or later to each i5/OS partition. Both methods allow console recovery without requiring an IPL of the partition.

HMC Console Error: "0099 Unknown Error Occurred - Contact Service"

If one HMC has an active 5250 console connection to a partition, an attempt to open another 5250 Console connection to the same partition from a redundant HMC will fail. The error message differs depending on the version of the HMC.

Version 4 Release 2.0 and earlier of the HMC returns the error: 00FF Unknown Error Occurred - Contact Service.

Version 4 Release 2.1 and later of the HMC returns the error: 0008 Session already in use.

In the case of networks with redundant HMCs, only one of the HMCs can have an active console connection. Console sharing (two or more consoles sharing the same session) is only available using the remote 5250 console function through one direct connected HMC.

To resolve the problem, first locate all redundant HMCs. On each redundant HMC, end any active local 5250 console session and any remote 5250 console session connected through that HMC.

Collecting System Dump

To collect a PHYP platform dump or System Dump, use Option 42 from the control panel. The system must be in manual mode.

Note: This will take down all partitions on the system.

If the system does not have a control panel, this Dump can be initiated from Advanced System Management.

Leave the default settings as shown, and click on Save settings and initiate dump:

 

 

 

 

 

 

 

 

 

New Console On the Block

The console on your AS/400, iSeries, or i5 system is the most important window in your I.T. environment. The system console can do things no other terminal connected to your system can do. Have you thought much about your console lately? Is this all-important window due for an upgrade?

Console History :

 1. System 38 – console built into the system unit.
    

 

2. Twin-ax 5250 console -  20 feet from the system unit maximum

3. PCs gain momentum 5250 emulation card allows PC to become system console Client access  PC console  iSeries access operations console & LAN console

4. Introducing The HMC - Hardware Management Console

First introduced on the pSeries A LINUX based PC appliance for eServer power5, Tied to specific PC hardware (xSeries), Ships with embedded OS pre-loaded, Closed and dedicated (can’t install other software on it) Required for configuration & management of logical partitioning, capacity on demand and some maintenance functions

Console Facts:

a.) System/38. The powerful predecessor of the AS/400 had one feature that stood out… the console and     keyboard were built right into the system unit.

b) When the AS/400 was introduced in 1988, two types of consoles were offered – ASCII or Twinaxial. I never saw an AS/400 with an ASCII console… Twinax was the reigning champion. Over time, IBM would enhance their lineup of 5250 display stations to include such features as multi-session and 132 column capabilities.

c) As personal Computers became more popular in the workplace, IBM came out with 5250 emulation cards. By installing one of these cards in a PC, you could open 5250 sessions and also turn your PC into a system console. All you had to do was to make sure you were connected to port 0 on the first workstation controller and that your address was set to 0. With Client Access came PC Console and, as Client Access became iSeries Access, PC Console grew into Operations Console.

d) The HMC is actually not a new device. It has been a part of the pSeries world since 2002. With the

convergence of the pSeries and the iSeries line becoming more of a reality, it was only a matter of time before the HMC would move into the iSeries world. The HMC and the i5 are a great fit. If an i5 is on the horizon for you and you plan to use LPAR and/or CoD, the HMC is going to provide all the tools you need to mange these environments and more.
