Blade serves HWstatus: unknown

[MyMatt]

Here is the environment:
SIM version 5.1
HP BladeSystem Integrated Manager 2.3
All enclosures are c7000
All our blades are BL465c G1 with PSP 7.91~8.11A, iLO version: 1.5~1.61

All blades were discovered successfully, 60% were shown under enclosures with correct information. The problem is on the rest of the blades:
They are listed under the enclosure with names like "RackName_EncName_Slot#-FRONT", not the system name I expected. The health status icon is a grey square, after I chose "resume monitoring", the health status became a blue dot with ? mark in it, and the health status is "HWstatus: unknown". ILO information are not displayed.
But if I search the system name in SIM, all the information shows up correctly except not mentioning the rack and enclosure info.

Anyone know what's going on? The trust setting in management homepage are all same.

Hi,

those are discovered systems through ilo or OA. You can delete those and discover your servers from LAN IP's

[MyMatt]

Still no luck by discoverying IP.

When I discovered the OA name, half of the servers are ok but rest just didn't come out with their system name.

[JKytsi]

all servers have agents configured properly (snmp)?

[MyMatt]

Yes, as all the problem servers has proper infomation displayed under SIM just missing the association part to enclosure...

Here's the screen cut

Is there a common ilO username/password on all servers and is this in the global protocol settings?

Try sending a repair agents to the servers and IP addresses that you cannot identify correctly.

[MyMatt]

Yes, we are using universal username and password.

Send the repair agent didn't work.
