Introduction

The information in this Readme contains hints and errata information about the Hardware Management Console. Please consult the HMC's technical support Web site for up to date information. (http://techsupport.services.ibm.com/server/hmc/power5).

All releases of the HMC Version 4.x machine code will manage an iSeries Server, but a pSeries Server requires HMC Version 4.2 (or greater) machine code.

 

Hints and Tips:

·       To launch the browser, right mouse click on the desktop to bring up the menu. Select "Net" and then "Browser".

·       To start a restricted shell terminal, right mouse click on the desktop to bring up the menu. Select "Terminals" and then "rshterm".

·       Currently, HMC only stores 4 service processor dumps and 4 platform system dumps per managed system.

·       Changes of a partition profile do not apply to the partition immediately. The changes will only take effect on the partition when activation is done through the profile.

·       If users are interested in keylock positions and SRC values when performing Operator Panel Service Functions through Service Focal Point, they can be viewed from the Server and Partition plugin.

·       To view system event logs, you must login as a user with ‘hmcpe role. From Service Applications, select Service Focal Point -> Service Utilities -> Actions -> View Problem Logs.

·       HMC Version 4 Release 2 or higher is required to manage pSeries Power5 servers.

 

Enhancements and Changes in V4R5

HMC Version 4 Release 3 and up now enables Ext3 File System. If you wish to take advantage of journaled file system, you must install or upgrade your HMC using the Version 4 Release 3 and  up Recovery CDs.

 

Server and Partition:

·       Server Management:

o      Provides support to configure  Switch Network Interface (SNI) adapters.

o      Provides command line function to list and force release the HMC lock on a managed frame.

o      Provides support for IO Concurrent Maintenance

HMC Code Update:

·       Improves Backup Critical Console Data performance.

HMC Command Line:

·       The following commands have been added:

·       dlslic – queries the Licensed Internal Code (LIC) level of each Power FRU

·       lslock – lists which HMC owns the lock on a managed frame

·       rmlock – forces an HMC lock on a managed frame to be released

·       An option has been added to the lslic command to list Licensed Internal Code (LIC) on High Performance Switches.

·       An option has been added to the lshwinfo command to display ambient air temperatures for the systems contained in a managed frame.

·       An option has been added to the lssvcevents command to display events that occurred during a specified number of preceding minutes.

·       An option has been added to the updlic command to upgrade Licensed Internal Code (LIC) to a new release.

·       An option has been added to the updlic command to update LIC on High Performance Switches.

·       The following commands have been enhanced to support Switch Network Interface (SNI) adapters: chsyscfg, lshwres, lssyscfg, and mksyscfg.

 

 

Known Issues:

Server and Partition:

·       Dynamic partition configuration for memory move can take a while. During that time, no other operation can be performed on the partition. 

·       After configuring your network setting, make sure to reboot your HMC. Otherwise, dynamic logical partitioning for AIX/Linux partitions may not work.

·       Users cannot change virtual Opticonnect and HSL Opticonnect settings through the GUI without activating the changes through a partition profile. Users can change the settings dynamically through the command line interface.

Usage: chhwres -m <managed system name> -r virtualio –-rsubtype virtualopti -p <partition name> -o s –a “virtual_opti_pool_id=[0|1]”

Usage: chhwres –m <managed system name> -r virtualio -–rsubtype hsl –p <partition name> -o s –a “hsl_pool_id=[0|1]”

·       Error messages for some Dynamic Logical Partitioning tasks give ‘AIX’ as the partition type even though it’s actually a Linux partition.

·       Unable to perform Dynamic Logical Partitioning virtual I/O remove operations if the partition does not have a current profile.

·       The HMC will display the wrong device information since the feature code 2849 is used for two different adapters :

OS/40                  p Linux                p AIX

    PCI 100/10Mbps Ethernet IOA           2849                    n/a                        n/a

    PCI 2D Graphics Accelerator               n/a                        2849                    2849

Only a visual inspection of the slot on the machine will be able to determine if the adapter is a Ethernet card or a Graphics card. Once the partition is activated with the adapter in the profile, the description should display proper adapter information.

·       After an FSP is replaced in a Power5 server, i5/OS partitions will not IPL properly and get B2xx 3110 SRC and B2xx 3200 SCR’s since the IPL Source is changed on the partition to D. On the HMC go to the Partition Properties Panel and select the Setting tab and change the IPL Source value and re-IPL the partition.

 

LIC Code Update:

·       If the HMC remote client loses its connection while it is downloading firmware, the download fails. Retry the operation “Change internal Code” might fail again with the message “Object is busy, and the task cannot handle busy objects”. Reboot the HMC and retry the “Change internal Code” operation.

·       Updating Licensed Internal Code on multiple Managed Systems in a p575 within the same power frame can be updated simultaneously by using the following procedure:

1.    Select one Managed System in each frame from the "Target Option Selection" panel.  This will update Licensed Internal Code on the Power Subsystem and the selected Managed System.

2.    Select the remaining Managed Systems in all frames from the "Target Option Selection" panel.  This will update Licensed Internal Code on the remaining Managed Systems.  The Power Subsystem was already updated in Step 1 and will not be updated again.

 

     Note that after Licensed Internal Code has been updated in Step 1, the image is saved on the HMC.  The "disk" repository can then be used for subsequent updates in Step 2.

·       Recovery procedure when error message “HSCF0052W Frame tttt-mmm*sssssss is locked by another process.” Is shown when performing Licensed Internal Code Update Operation on the p5 595, i5 595, p5 590 and p5 575 managed systems, verify that no other frame operations that uses the lock listed below:

·       Repair and Verify Operation

·       Initilaize Frame Operation

·       Ste Frame Number Operation

·       Licensed Internal Code Update

 

     is in progress on a remote HMC or on a dual HMC. Then issue the rmlock command to force release the HMC lock on a managed frame.

     Usage: rmlock  e <frame name>

 

HMC Code Update:

·       Beginning with HMC Version 4 Release 5.0, the Install Corrective Service will allow prompting of multiple media or update zip files, and only require a reboot when all the media or update zip files are processed. However, if you are using the Install Corrective Service from a version prior to HMC Version 4 Release 5.0, you must reboot the HMC after installing the first update cd or zip file.

National Language Support:

·       Mnemonics are not supported in double byte and ru locales.

·       The HMC uses several external components. These components are not developed by the HMC team and are translated as part of a separate translation plan and schedule. The mix of English and translated text is an unavoidable situation and has the potential to occur anytime the HMC is updated or pulls in a new version of an external application that is updated in between its normally scheduled translation cycles. 

·       Due to the limitation of groff, some characters in the output of "man" command might be corrupted in traditional Chinese, simplified Chinese and Korean when the window is too narrow. Widen the window and retry the command again.

·       Korean input is supported. Press Shift-Space to switch between English and Korean input mode.

·       Traditional and Simplified Chinese input is supported in zh_TW and zh_CN locales. Press CTRL-Space to switch between English and Chinese  input mode. Press CTRL-Shift to select an input method. Press space bar to see more Chinese characters.

·       Japanese input is supported. Press Shift-Space to switch between English and Japanese input mode.

·       User ID, User information, HMC User password, Partition name, managed system name, profile name and system  profile name are in English only.

·       IBM275 doesn't work well when connecting from IBM Personal Communications or iSeries Access to an HMC. Use another Brazil codepage. The codepage "IBM930 Japan Katakana" doesn't work well either. Use "IBM930 Japan Katakana Extended" instead.

·       An ibm5250 session opened on the HMC locally will be in the same locale as the one that is set for the HMC. To open a session in a different locale, change the HMC locale first, logout, login and then invoke ibm5250. The other option is to connect to the HMC using a remote emulator, e.g. IBM Personal Communications or iSeries Access, in the desired locale.

Miscellaneous Functions:

·       Help Search is not supported. However, Find is supported for Help.

·       Printing is not supported.

·       The numerical keypad on some keyboards doesn't work. Use the normal numerical keys instead.

·       When your power5 system is shipped to you it is in a non-HMC managed mode by default. Once you attach and set up an HMC to manage your power5 system, the default non-HMC managed mode is exited. The procedure to return to the default non-HMC managed mode is documented on the InfoCenter website under “Resetting the server to a non partitioned configuration”.
