Each partition will have a unique 17*4882a593Smuzhiyun partition id. To display the partition id, use the command:: 18*4882a593Smuzhiyun 19*4882a593Smuzhiyun cat /sys/firmware/sgi_uv/partition_id 20*4882a593Smuzhiyun 21*4882a593Smuzhiyun The coherence_id entry contains the coherence id. 22*4882a593Smuzhiyun A partitioned SGI UV system can have one or more coherence 23*4882a593Smuzhiyun domain. The coherence id indicates which coherence domain 24*4882a593Smuzhiyun this partition is in. To display the coherence id, use the 25*4882a593Smuzhiyun command:: 26*4882a593Smuzhiyun 27*4882a593Smuzhiyun cat /sys/firmware/sgi_uv/coherence_id 28
