Hi all,
I'm pretty new to OVirt so forgive me if this problems is trivial...
I received an old IBM BladeCenter H chassis with a few HS22 blades. Some of them are successfully working in my Ovirt farm, but some not. The NonOperational nodes are not used because of missing Westmere model. I use 4.3.10 wersion because 4.4 did not supported some old HW (net adapters, IIRC).
The problem is that many blades are almost identical. For example ("Hosts" page --> "General" tab --> "Hardware" section):
* BLADE 1 (not working): Manufacturer:IBM Family:System x Product Name:BladeCenter HS22 -[7870H4G]- Version:07 UUID:e36b6686-d111-11df-9dce-e41f13cb90d0 Serial Number:06FP476 CPU Model Name:Intel(R) Xeon(R) CPU X5670 @ 2.93GHz CPU Type:Intel Nehalem IBRS SSBD Family CPU Sockets:2 CPU Cores per Socket:6 CPU Threads per Core:2 (SMT Enabled)
* BLADE 2 (working fine): Manufacturer: IBM Family: System x Product Name: BladeCenter HS22 -[7870H4G]- Version: 07 UUID: 30f2fcc8-d0ce-11df-bc12-e41f13cb90cc Serial Number: 06FP469 CPU Model Name: Intel(R) Xeon(R) CPU X5670 @ 2.93GHz CPU Type: Intel Westmere IBRS SSBD Family CPU Sockets: 2 CPU Cores per Socket: 6 CPU Threads per Core: 2 (SMT Enabled)
They have same CPU, same HW model, even S/N shows they were produced in the same time. How is it possible to identify X5670 so differently? Any hints/suggestions what to check/change?
Most likely they have some different configuration in the BIOS/CMOS/etc. setup. Perhaps also try comparing the output of 'cat /proc/cpuinfo' between them, and search general linux documentation about the meaning of the flags that are different between them. Good luck and best regards, -- Didi
