Hardware Management Console Best Practices

- 31 -

• -c Collect trace files and (optional) stack traces of various subsystems. This

initiates an interactive task which will prompt for verification if trace for

certain subsystems should be collected. All files will be collected into a zip

file, and the option to store to the HMC filesystem or DVD will be given. If

the former is chosen then root access will be needed to extract the zip file

from the HMC (see below) or the sendfile HMC CLI can be used. This

file can later be deleted from /dump using the –r attribute once the log file

has been handled appropriately.

One case where ped/jointfilesconvert/366647/bg will not be as helpful for trace logging is for the remote

HMC Console application. On Windows

platforms from where this Console

can be launched, the following must first be typed at a command prompt prior to

launching the Console (assuming ped/jointfilesconvert/366647/bg was already run on the HMC):

dir > c:\program files\websm\config\wsmdebug

wsm.bat 2>\temp\stderr.log 1>\temp\stdout.log

It is the presence of wsmdebug in the correct directory that enables the tracing.

Note that for the second command, the PATH environment variable will be set up

for all users during WebSM installation such that this command can be executed

from any directory. AIX and Linux users of wsm can use the following

command:

# touch /tmp/wsmdebug

While ped/jointfilesconvert/366647/bg should suffice for enabling trace collection, situations can arise

where it will be helpful for support to gain root-level access on the HMC. One

example was given above: extracting the zip file from /dump. The HMC has a

restricted shell which can be accessed via SSH or by selecting an rshterm from the

pop-up menu on the console. (This menu is accessed by right clicking in the grey

area of the screen.)

The HMC provides a command to escape temporarily from the restricted shell:

pesh. This command may only be run by user hscpe with task role hmcpe.

This command accepts one parameter – the HMC serial number – which can be

obtained by issuing the command lshmc –v (see the “SE” tag attribute). You

will then be prompted for a password, which you must obtain from IBM Support.
