I believe it uses a combination of the NFS mntinfo kstat, and the mnttab file. Places to start looking are: # get_pretty_name() http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/stat/common/acquire_iodevs.c#539 # lookup_nfs_name() http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/stat/common/dsr.c#511 does this help? The common "snapshot" code in the above is called by vmstat, iostat & mpstat, e.g: iostat -> acquire_snapshot() -> acquire_iodevs() -> get_pretty_name() -> lookup_nfs_name() cheers, calum.
