hi jakub,
I have set MIITOL variable to non-existent-file, like this:
#MIITOOL=/sbin/mii-tool
MIITOOL=/sbin/mii-tool-non
but got this when one switch turn off (we do HA test)
rac 10.2.0.4.4
bond0 is bonding for virtual ip, switch is trunked
bond1 for heartbeat.
2010-05-29 06:33:32.803: [ RACG][51317200]
[5674][51317200][ora.radpadb2.vip]: clsrcep:evm post return 1
2010-06-03 18:19:23.210: [ RACG][51317200]
[27658][51317200][ora.radpadb2.vip]: ping to 10.33.200.1 via bond0 failed,
rc = 1 (host=radpadb1)
ping to 10.33.200.1 via bond0 failed, rc = 1 (host=radpadb1)
Interface bond0 checked failed (host=radpadb1)
Invalid parameters, or failed to bring up VIP (host=radpadb1)
so, even node1 still alive, but from client/app server cannot connect to it.
node2 was restarted, due to share switch for public and heartbeat :)
this is blade world...we had no flexible networking on it :(
