Hardware Management Console Best Practices

- 33 -

7310-C03 desktop model, or 7310-CR2 / 7310-CR3 rack-mount models, make

sure the hyperthreading option under the Advanced options in BIOS is disabled.

On these models, this can be verified on the command line as user root by

typing:

dmesg | grep -i hyper

There will be no output if hyper threading is disabled.

Performance can suffer if trace and log files fill the HMC file system. Disk space

usage can be checked by typing (only as user root!) ‘df –h’ . If any

filesystem partition is in 100% use, your service provider should be consulted.

The managed systems and frames can be in one of many states, as reported by the

HMC. A description of managed system states can be found at:

http://publib.boulder.ibm.com/infocenter/iseries/v1r2s/en_US/info/ipha1/poweron

states.htm,

A description of frame states can be found at:

http://publib.boulder.ibm.com/infocenter/iseries/v1r2s/en_US/info/ipha1/framepo

weronstates.htm.

Among the states that cause confusion:

• No Connection: The HMC cannot build a valid connection to the FSP / BPC.

The reason will be displayed as an error code under the Op Panel value column

on the GUI. If you believe that this state has been reached in error, you can

reset the network connection between the HMC and FSP. By right-clicking on

the managed system to bring up the pop-up menu, or selecting the managed

system and going to the ‘Selected’ menu, select ‘Reset or Remove’ Connection

on the HMC Console. You must have task role hmcsuperadmin,

hmcoperator, or hmcpe to perform this operation. You can also initiate

this task from the command line: rmsysconn command with –o reset flag.

• Definitions for No Connection codes, as well as corrective measures that can be

taken, can be found at
