I have configured a serverfarm with two servers that are required by license to be active-passive:
probe http rush1
interval 10
faildetect 1
passdetect interval 5
passdetect count 1
receive 5
request method get url /mrush?operation=ding
expect status 200 200
open 5
expect regex dong
serverfarm host rush
probe rush1
rserver rush1
backup-rserver rush2
inservice
rserver rush2
inservice standby
rserver host rush1
description RUSH server
ip address 192.168.0.101
probe rush1
inservice
rserver host rush2
description Backup RUSH server
ip address 192.168.0.102
inservice
however, regardless of how I fail over, the second server never leaves 'standby' and does not respond to requests... the counters on the serverfarm go up, including the failuers, on the backup rserver
serverfarm : rush, type: HOST
total rservers : 2

This looks strange behavior. I suspect a bug but have not found similar one.
In my lab, rserver state goes OPERATIONAL from STANDBY when primary
server goes PROBE-FAILED. (This is expected behavior.)
Did you configure as following step only? If not, could you please let me know
your config step? (For example, configure rserver rush1 and rush2 in serververm
and then change configuration with backup-rserver command.)
1) configure probe
2) configure rserver rush1 and rush2
3) configure backup-rserver rush2 in serverfarm (not configure rserver rush2 by hand)
And also, could you please let me know the ACE version and the number of
'active rservers' in 'show serverfarm detail'?
ACE20/Admin# show ver | i image
system image file: [LCP] disk0:c6ace-t1k9-mz.A2_3_1.bin
ACE20/Admin#
ACE20/Admin# show serverfarm detail
serverfarm : sf, type: HOST
total rservers : 2
active rservers: 1 <<==
description : -
state : ACTIVE

When primary server goes down (PROBE-FAILED), does only 'failures' counter of
rush2 increase?
real weight state current total failures
---+---------------------+------+------------+----------+----------+---------
rserver: rush1
192.168.0.101:0 8 PROBE-FAILED 0 1361 25
rserver: rush2
192.168.0.102:0 8 STANDBY 0 0 12 <<== increase this counter?
