| + | Starting with AIX 7.2 TL5 SP3 (and VIOS 3.1.3.00), AIX/Power system administrators can use an alternative to kdb for viewing VIOS "identifying info" from client AIX LPAR’s. i.e. | ||
| + | |||
| + | <cli promt='#'> | ||
| + | # cat /proc/sys/adapter/fc/fcs0/hostinfo | ||
| + | fcs0 | ||
| + | VFC client adapter name : fcs0 | ||
| + | Host partition name (VIOS) : vio1 | ||
| + | VFC host adapter name : vfchost0 | ||
| + | VFC host adapter location code : U9009.22A.7871D00-V3-C7 | ||
| + | FC adapter name on VIOS : fcs2 | ||
| + | FC adapter location code on VIOS : U78D3.001.WZS0AL9-P1-C8-T1 | ||
| + | </cli> | ||
| + | |||
| + | //Note// If your VIOS is not running the latest VIOS code, 3.1.3.00, you'll find that the "FC adapter name on VIOS" attribute will be blank | ||
| + | |||
| + | |||
| + | == You can mask theses informations on the VIOS == | ||
| + | |||
| + | It is worth noting that you can prevent this information from being available to the client LPAR by changing the secure_va_info attribute on your 3.1.3.00 VIOS. | ||
| + | |||
| + | For example, if we were to change the secure_va_info value from no to yes, like so: | ||
| + | <cli prompt='$'> | ||
| + | $ chdev -dev viosnpiv0 -attr secure_va_info=yes | ||
| + | viosnpiv0 changed | ||
| + | |||
| + | $ virtadapinfo -list | ||
| + | secure : yes | ||
| + | </cli> | ||
| + | |||
| + | Then the client LPAR will see the following (Secure) output for that VIOS: | ||
| + | <cli prompt='#'> | ||
| + | # cat /proc/sys/adapter/fc/fcs1/hostinfo | ||
| + | VFC client adapter name : fcs1 | ||
| + | Host partition name (VIOS) : Secure | ||
| + | VFC host adapter name : Secure | ||
| + | VFC host adapter location code : Secure | ||
| + | FC adapter name on VIOS : Secure | ||
| + | FC adapter location code on VIOS : Secure | ||
| + | </cli> | ||
