Help me,why HA fail ?

Hello,all.

 

 

I used to two virtual BIGIP that HA Lab, but fail,

 

 

the two BIGIP version is "BIG-IP 10.1.0 Build 3341.1084 Final "

 

 

BIGIP_1-------(HA mode Network Failover )--------BIGIP_2

 

 

HA mode Active-active

 

 

High Availability : Redundancy, unit 1 of BIGIP_1 device,unit 2 of BIGIP_2 device.

 

 

BIGIP_1: ConfigSync Peer Address set 198.18.19.252 ,BIGIP_1 management ip address is 192.168.0.105

 

BIGIP_2: ConfigSync Peer Address set 198.18.19.251 ,BIGIP_2 management ip address is 192.168.0.106

 

Detect ConfigSync Status enable

 

 

 

BIGIP_1: failover1|198.18.19.251|198.18.19.252|1026

 

failover2|192.168.0.105|192.168.0.106|1026

 

 

BIGIP_2: failover1|198.18.19.252|198.18.19.251|1026

 

failover2|192.168.0.106|192.168.0.105|1026

 

 

network mirroring:

 

BIGIP_1:Self _198.18.19.251,remote_198.18.19.252

 

BIGIP_2:Self _198.18.19.252,remote_198.18.19.251

 

 

 

High Availability-Fail_self--gateway:

 

 

add pool : failover_pool, pool member only include 198.18.19.1(default gateway),health moniter select "gateway_icmp"

 

 

ok, them can Synchronize configuration,but not switch over ,

 

 

down BIGIP_2 , BIGIP_1 can't take over BIGIP_1 's traffic .

 

 

b unit command on BIGIP_1 , display unit 1 :

 

[root@BIGIP_1:Active] config b unit

 

UNITS 1

 

 

reboot BIGIP_2, b failover standby command on BIGIP_2,and b unit command on BIGIP_1,dispaly:

 

 

[root@BIGIP_1:Active] config b unit

 

UNITS 1 and 2

 

 

but shutdown BIGIP_2,

 

 

[root@BIGIP:Active_] config b unit

 

UNITS 1 and 2

 

 

why ? ?

 

 

more /var/log/ltm

    Hi Gavin,

     

     

    HA configurations aren't supported for the virtual edition. This limitation is described in the VE 10.1.0 release notes (Click here). A poster (Click here) suggested that he got HA to work though.

     

     

    It seems like your HA configuration might be working, but the monitor is marking the gateway down. You might try focusing your troubleshooting on why the unit can't ping the failover_pool member.

    unit 1 of bigip ,unit 2 of bigip . HA mode active-active

     

     

    on bigip unit 1 ,type : b failover standby , and on bigip unit 2 ,type: b unit , display : unit 1 unit 2 , so HA is ok .

     

     

    on bigip unit 2 ,type : b failover standby , and on bigip unit 1 ,type: b unit , display : unit 1 unit 2 , so HA is ok .

     

     

    are you know ?

     

     

    but power off BIGIP unit 1 , on BIGIP unit 2 b unit ,display: unit 2 , not display unit 1 unit 2 , I don't understand this .

     

     

    again ,power off BIGIP unit 2 , on BIGIP unit 1 b unit ,display: unit 1 , not display unit 1 unit 2 ,

    by the way , I creat same singel virtual server(VIP) on BIGIP 1 and BIGIP 2 , define virtual server name is "WebServer"" ,

     

     

    Power off BIGIP 1 or BIGIP 2 ,external client can connect "WebServer" ,if "WebServer" unit set 1 on BIGIP 1 and "WebServer" unit set 1 on BIGIP 2.

     

    Power off BIGIP 1 or BIGIP 2 ,external client can't connect "WebServer" ,if "WebServer" unit set 1 on BIGIP 1 and "WebServer" unit set 2 on BIGIP 2.
