The rboard 283 * structure also has a pointer to the ERRORINFO structure. This is 284 * the place to store ERRORINFO about a REMOTE NODE, if the HUB on 285 * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where 286 * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can 287 * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info 288 * which is present on the REMOTE NODE.(TBD) 289 * REMOTE ERRINFO can be stored on any of the nearest nodes 290 * or on all the nearest nodes.(TBD) 291 * Like BOARD structures, REMOTE ERRINFO structures can be built locally 292 * using the rboard errinfo pointer. 293 * 294 * In order to get useful information from this Data organization, a set of 295 * interface routines are provided (TBD). The important thing to remember while 296 * manipulating the structures, is that, the NODE number information should 297 * be used.
