GTM marking LTM VIP down even when VIP is up

Hi All,

I have an issue where in a wideip on the GTM one of the members is marked down. The member is actually a VIP on the LTM. Aftre checking the LTM i see that VIP is up.

Wideip has two pools: PRI and SEC. PRI is up but SEC is marked down.

Wideip has below IRULE which decides the resolution :

gtm rule /Common/CPORMS-TEST_CNAME {

when DNS_REQUEST {

ttl 30

set members [active_members cporms-test_s_SEC]

if { $members > 0 } {

   cname "cporms-test2.com"

   } else {

    cname "cporms-test1.com"

   }

}

}

But since SEC pool member is being marked down by the GTM the application is not resolved as expected.

Iquery is happening between GTM and LTM but still member is marked down on the GTM.

Any suggestions as to what needs to be checked further ?

Thanks in advance,

Vineet

    Is it always marked down? does say in the log when it got marked down? I think it's /var/log/gtm or maybe /var/log/ltm.... Under servers view, you see the LTM green? and under its virtual servers, you see all expected VIPs in correct state?

    Hi Mohamed,

     

    Well actually after investigating found out that the translation address was not correct which is why GTM was marking it down.

     

    Connection was as below: External user--> GTM--> Firewall-->LTM

     

    Translation address was not correct on the GTM.

     

    Was just wondering why actually translation should be mentioned on the GTM. Any comments?
