Re: [aperi-dev] Problems and doubts about Aperi SRM and San Simulator
|
Hi Amudhan,
Thats great. Aperi SRM supports discovery of CIM/SMI-S compliant storage
subsystems. But, pls. check, if Aperi SRM is enabled for CIM/SMI-S
discovery of FC Switches.
I think current Aperi SRM supports discovery of FC switch through Brocade
API and not through CIM/SMI-S.
>From SAN Simulator point of view, it simulates Brocade FC Switch. You can
discover it through SBLIM eCute, but I don't think thats what you are
looking for :-(

Hi Ramani,
Thanks for your very useful tips, now I am able to simulate more than one
storage subsystems.
But, your workaround to have both Storage and Switch did not work. I did
exactly what you told.
1) Installed one storage device (Configuration-Based, as it would always be
in my case)
2) Installed one switch (Brocade switch)
3) Started the CIMOM of the storage. Discovered it Probed, stopped it and
removed the cimom.
4) Started the soap service with "java -classpath .\soap.jar
org.apache.soap.util.net.TcpTunnnelGui 5988 localhost 5999"
5) I tried to add a new CIMOM in Aperi SRM with IP, port = 5999
But I got Unreachable error. So, I quit the tunneling and tried with 5988
(and it said invalid namespace for /root/brocade and I changed to /interop)
and it worked. I was successfully able to add the CIMOM but even after
doing the discovery, I did not see any managed device. When I clicked *Show
Managed Device* in Agents->CIMOM, it said, *no managed element was found*.
Is it because of the attempt I made? or is it the behaviour? I am having
done these attempts, how can I successfully discover a managed switch (I am
okay even if I have to lose the details I got about the storage).
Thanks in advance!

Amudhan

Hi Amudhan,
1. Thanks for the suggestion. We will look into your suggestion of
handling
the presence of 'space' in JAVA_HOME ( we wanted to make very minimal
modification to the Sun WBEM CIMOM startup batch file -- modified to add
the root and simulator jar files).
2. To have two storage subsystem CIM agents simulated in a single SIMDB
under a single instance, you can follow the following steps
2.1) Start a fresh install. Create SIMDB
2.2) Run setup.bat. Choose Type = Configuration Based, Device=
Storage Subsystem DS8K-5.1.0.40,
2.3) Choose and select the options i) Create New CIMOM (e.g.
c:\SAN_Simulator_SS) ii) Start CIMOM and Compile MOF Files iii) Generate
Config/snapshot based simulation data
2.4) Finish the installation. Start the CIMOM. At this point, this
simulated CIM agent will report one IBM DS8000 Storage Subsystem
2.5) Stop the CIMOM. Run setup.bat again
2.6) Run setup.bat. Choose Type = Configuration Based, Device=
Storage Subsystem DS8K-5.1.0.40
2.7) Choose and select only the last option iii) Generate
Config/snapshot based simulation data
(Do NOT select these two options i) Create New
CIMOM (e.g. c:\SAN_Simulator_SS) ii) Start CIMOM and Compile MOF Files )
2.8) Finish the installation. Start the CIMOM. At this point, this
simulated CIM agent will report two IBM DS8000 Storage Subsystems
(Note: You can add multiple devices of same type this way because MOF
file
for the device <type,version> has been compiled in the first instance.
You
are updating the repository(SIMDB) by adding one device at a time of same
type in this fashion.)
You can modify the config file, if you wish to change the configuration
of
a single device (e.g. if you wish to increase number of pools in a
storage
subsystem).
3. The above step shows how to have two Storage Subsystems simulated
using
configuration based option. If a real live CIMOM is reporting one or more
Storage subsystems(or any number of devices) and you are snapshotting it,
the simulated CIMOM will copy and report the same number of storage
subsystems.
4. We will look into the two questions you have raised in the MOF
compilation code.
Thanks for your feedback.

Hi All,
First of all, I would like to thank everyone. The real problem had been
the
'space' between the "Program Files". In "simulator_start_cimom.bat" a
check
is made like *if exist %JAVA_HOME%\LICENSE goto JAVA_OK*. Because of the
presence of 'space' in JAVA_HOME the condition turned out to be 'false'
and
everything got collapsed. I modified the bat file to *if exist
"%JAVA_HOME%\LICENSE" goto JAVA_OK* (and again I got the same problem...
but this time, it is from the construction of one more variable called
JAVA
which uses JAVA_HOME to execute java command. I changed there also to
include the quotes) and it worked fine.
I think it would be really great if the bat files are changed in the
installation source itself to have quotes in them (and it may save a lot
of
time to those who will try in the future). I think the workaround in the
thread http://dev.eclipse.org/mhonarc/lists/aperi-dev/msg00915.html had
worked because the java EE sdk by default gets installed in "C:\sun\sdk\"
and it has no spaces. That work around did not work for me as I had
already
changed the bat files to have *set JAVA_HOME=C:\Program Files\Java
\jdk1.5.0_11*.
Ramani, I will now try your workaround\hack for simulating both storage
and
switch at the same time. But I have a small doubt. You said like,
simulating two storage subsystem is easy. I want to know how? Should I
change the conf file corresponding to the storage subsystem I am going to
simulate? If so, could you please guide me how to do that? (I will try
out
the tunneling stuffs now to simulate both switch and storage. If I face
problems, I will send out a mail immediately).
===the content below is a small doubt in one of the classes
org.eclipse.aperi.simulator.ui.CompileMof. Anyone interested could
clarify
my curious doubt===
As Pallavi suggested I went through SetupWizard.log and found that the
error "Error Compiling MOFs" come from
org.eclipse.aperi.simulator.ui.SetupProcess SetupSANSimulator method
which
in turn called org.eclipse.aperi.simulator.ui.CompileMOF compileMof
method
which I was responsible for the error message. I extracted the jar and
decompiled the classes to see the source (I do not have aperi source yet)
and found that, the SetupSANSimulator method in CompileMof class has a
code
segment:
File mofFiles[] = mofFileLoc.listFiles();
for(int i = 0; i < mofFiles.length; i++)
{
if(!mofFiles[i].getAbsoluteFile().toString().contains("Interop"))
continue;
compileMofFileCommand = "\"" + SetupWizardUtility.getProperty
("DIRECTORY_LOCATION_TO_INSTALL_CIMOM") + "\\wbemservices\\bin
\\mofcomp.bat" + "\"" + " -u administrator -p passw0rd " + "\"" +
mofFiles
[i].getAbsolutePath();
logger.info("Compile Mof Command: " + compileMofFileCommand);
if(executeCommand(compileMofFileCommand) != 1)
return false;
}
for(int i = 0; i < mofFiles.length; i++)
{
if(mofFiles[i].getAbsoluteFile().toString().contains("Interop"))
continue;
compileMofFileCommand = "\"" + SetupWizardUtility.getProperty
("DIRECTORY_LOCATION_TO_INSTALL_CIMOM") + "\\wbemservices\\bin
\\mofcomp.bat" + "\"" + " -u administrator -p passw0rd " + "\"" +
mofFiles
[i].getAbsolutePath();
logger.info("Compile Mof Command: " + compileMofFileCommand);
if(executeCommand(compileMofFileCommand) != 1)
return false;
}
Curiosity No:
1. The created compileMofFileCommand does not close the opened quote
for
mofFiles[i].getAbsolutePath(). Is there any specific reason for
that?
2. In both the for loops, the if condition is just the opposite to
each?
other. So, any how all the files will be processed. Then why should
there be two *for* loops? What difference it would make if there was
only one *for* loop with no *if* condition?
I would soon send mails with the status about tunneling and simulating
storage and switch at the same time.
Thanks for all your helps!
Regards,
Amudhan.

What OS are you running the Aperi agent on?
Looks like NetWare? and afaik the NetWare specific agent
code is not included in Aperi - hence the class loader
failure.
Hth,
