problem adding another cpu to K260

[Tony Kim]

I'm trying to add one additional cpu to a single processor K260 server. I've enabled the new CPU via ISL, "cpuconfig 1 on" command. After a reset I see that the 2nd cpu is still not functioning. I know that both CPUs are good cause when I boot the box with each they work perfectly. I've tried this on two separate K260's and I get the same problem. What am I missing? Appreciate your help.

Hi,

Pls chk if both of them are **claimed** by the system:

#ioscan -fk|grep -i proc

I did and only the first CPU is seen.

# ioscan -fk|grep -i proc
processor 0 32 processor CLAIMED PROCESSOR Processor

Are they of the same type? Post part numbers (seen on the CPU boards) here

Did yo check the K260 CPU Upgrade guide? If not, here it is:

Problem resoved! Thanks to all who responded. I've used a differnt spare CPU we had and they seem to work fine together. I guess it was due to a flaky CPU.

Glad you solved it, but if the PDC (Processor Dependent Code) levels on each processor are incompatible that would do it as well.
