The rboard 281 * structure also has a pointer to the ERRORINFO structure. This is 282 * the place to store ERRORINFO about a REMOTE NODE, if the HUB on 283 * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where 284 * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can 285 * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info 286 * which is present on the REMOTE NODE.(TBD) 287 * REMOTE ERRINFO can be stored on any of the nearest nodes 288 * or on all the nearest nodes.(TBD) 289 * Like BOARD structures, REMOTE ERRINFO structures can be built locally 290 * using the rboard errinfo pointer. 291 * 292 * In order to get useful information from this Data organization, a set of 293 * interface routines are provided (TBD). The important thing to remember while 294 * manipulating the structures, is that, the NODE number information should 295 * be used.
