This section describes how you can correlate the information that is reported by the Oracle Solaris Fault Management Architecture (FMA) with the logical domain resources that are marked as being faulty.
FMA reports CPU errors in terms of physical CPU numbers and memory errors in terms of physical memory addresses.
If you want to determine within which logical domain an error occurred and the corresponding virtual CPU number or real memory address within the domain, then you must perform a mapping.
The domain and the virtual CPU number within the domain, which correspond to a given physical CPU number, can be determined with the following procedures.
primary# ldm list -l -p
The domain and the real memory address within the domain, which correspond to a given physical memory address (PA), can be determined as follows.
primary# ldm list -l -p
Here pa and size refer to the values in the corresponding fields of the line.
Suppose you have a logical domain configuration as shown in Example 12-1, and you want to determine the domain and the virtual CPU corresponding to physical CPU number 5, and the domain and the real address corresponding to physical address 0x7e816000.
Looking through the VCPU entries in the list for the one with the pid field equal to 5, you can find the following entry under logical domain ldg1.
Hence, the physical CPU number 5 is in domain ldg1 and within the domain it has virtual CPU number 1.
Looking through the MEMORY entries in the list, you can find the following entry under domain ldg2.
Where 0x78000000 <= 0x7e816000 <= (0x78000000 + 1073741824 - 1); that is, pa <= PA <= (pa + size - 1). Hence, the PA is in domain ldg2 and the corresponding real address is 0x8000000 + (0x7e816000 - 0x78000000) = 0xe816000.
