hi,
i have installed netxms in an environment which includes ibm blade center.
the blade center is discovered about 21 time and the objects remain in the root of the object tree and not under the subnet.
what can be the cause for this ?
Best Regards,
Lindeamon
Hi!
I suspect that NetXMS server incorrectly process some information obtained from device. Could you please send me more information about this object(s)? I'm mostly interested in information shown on summary page (capabilities, OID, system description), list of interfaces with IP addresses, and IP address selected as primary. I don't need to know exact IP addresses, but very important is to check that address selected as primary IP is presented on one of interface objects.
Best regards,
Victor
hi victor,
i will give you the info.
b.t.w i use the network discovery on all the time and server keeps adding the same ip of the management module again and again.
instead of one node per management module i have like 25
Best Regards and good to be back,
Lindeamon
hi victor,
i have attached 2 screenshots of the fibre channel module that is the problematic one.

Lindeamon
Hi!
Can you confirm that IP address 172.16.4.41 presented on one of the interfaces of the node?
Best regards,
Victor
hi victor,
those ip address are belong to the fiber channel modules of the blade center.
the cage has 2 options for networking:
1. the management port.
2. the network module ports.
every module has it's own ip address so it could be configured but i do not know from which network capable module i connect to the management of the modules.
Best Regards,
Lindeamon
hi victor,
i have done a little research and what i have found out that by default the communication to the fiber-channel module is made through the management module.
every module in the cage has it's own ip address.
what i have experiencing is that every period of time both of the fiber channel modules are being rediscovered and for some reason the server can not place them under the subnet tree.
hope this help you solve the problem.

Lindeamon
Hi!
I have some ideas why this can happen. I do some fixes already, next release will contain them. Hopefully it will help.
Best regards,
Victor
hi victor,
great news.when the next release will be out ?
Best Regards,
Lindeamon
Hi!
I hope that it will be before end of March, but I have planned quite a lot for this release, so maybe it will be delayed till first half of April, depending on how fast I'll be able to do development.
Best regards,
Victor
Hi victor,
do not want to rush you,but it is kind of driving me crazy.
i will wait patiently.

Lindeamon
hi victor,
i have upgraded the server and all to 1.2.0 and from first impression i can see that it does not re-detect the hba modules but it does not place them under the subnet container in the "entire network" tree.
i will wait until tomorrow to see if the hba's are being rediscovered and will keep you posted.
Best Regards,
Lindeamon
hi victor,
now i can say for sure that the hba modules are not redetected but thay are not placed under the correct place in the subnet tree.
i can tell you that in the ibm blade center there are 2 management modules and the hba modules management interface is routed through them meaning that if the management module is down there will be no network connectivity to the hba module.
Best Regards,
Lindeamon
Hi!
Can you please show me all interfaces under hba module with IP addresses and primary IP address of HBA module? I suspect that module's primary address is not visible on any of it's interfaces, and this is why NetXMS server doen not place them into subnet tree.
Best regards,
Victor
hi victor,
I will give you the info tomorrow when i get back to work.

hi victor,
i have attached 3 screen shots of the FC module.basically "bay x" means the number of the blade and "ext x" means the ports connected to a san storage or switch.
it has a management or sup interface that holds it's ip but the communication to the module is routed through the blade management module which have a different ip, in this case is 172.16.4.60
Best Regards,
Lindeamon
hi victor,
i do not know where you stand on this issue but i just want to update you that apparently the fc modules are discovered and in former version they where located under "business.." but now i do not even see them and get alarm for them.
Best Regards,
Lindeamon
correction...
i can't see them but i receive alarms for them
Are you 100% sure that they are nowhere in the tree? Try to do IP address filter in object tree - enter > followed by IP address in filter field.
Best regards,
Victor
i am sure and the reason for that is that only when i upgraded to 1.2.1 i got alarms for them i then i have noticed that instead of residing some where in the tree they are gone.
i will do the requested check and let u know
Best Regards,
Lindeamon
hi victor,
i have looked for the object and they are not there.
Best Regards,
Lindeamon
That's very strange. When possible, can you stop the server and run database check? Will it report any errors?
Best regards,
Victor
hi victor,
u were right. running the db check found the unlinked object.why wasn't i informed of this ?
is it a bug ?
Best Regards,
Lindeamon
Hi!
It's definitely a bug in the server which leaves some nodes unattached to neither subnet nor container object. I have one fix possibly related to this in 1.2.2 - may be it helps. If not, I'll have a chance to connect IBM blade to NetXMS in a couple of weeks, then I'll be able to do necessary tests.
Best regards,
Victor
hi victor,
obviously i will have to wait and see if it will help.
after i have done the checking the missing nodes were not found again although the network discovery is active. i will check tomorrow to see if they were rediscovered and i will let u know
Best Regards,
Lindeamon
hi victor,
done the check and found that although i get alarms from the FC modules i do not see them anywhere.
need to solve this quickly
Best Regards,
Lindeamon
hi victor,
no luck. i have ran the db check and fixed the errors and still no nodes and just alarms.
guess you will check that after the vacation
Best Regards,
Lindeamon
Can you dump server objects by running command
nxadm -c "sh o" > file
and try to find records for problematic objects in that file, and send them to me?
Best regards,
Victor
hi victor,
will do that coming sunday
Best Regards,
Lindeamon
hi victor,
i invoked the command and did not find any thing.i will wait till you have access to blade center as you said earlier
Best Regards,
Lindeamon
hi victor,
i have installed v1.2.3 this morning and by now i would expected the system to find the FC Management nodes, but it didn't therefor my problem is not solved.
i have done db check and nothing.
i hope you have access to a blade center to try and solve this problem
Best Regards,
Lindeamon
