NimbostratusPersistence across virtuals
Environment: 11.6.0 HF6 on a vCMP guest
I have two virtual servers, one with a persistence profile and one without. I am trying to query the persistence table from an iRule on the VS without a persistence profile, and the query is returning nothing. Is there some requirement for configuring a VS to allow it to query the persistence table?
VS with persistence
ltm virtual VS_jenise {
destination 1.1.1.1:http
ip-protocol tcp
mask 255.255.255.255
persist {
JenUniversal {
default yes
}
}
pool pool_jenise
profiles {
http { }
tcp { }
}
source 0.0.0.0/0
source-address-translation {
type automap
}
vs-index 18
}
ltm persistence universal JenUniversal {
app-service none
defaults-from universal
rule JenPersistence
timeout 1800
}
ltm rule JenPersistence {
when CLIENT_ACCEPTED {
set myKey JEN2
persist uie $myKey 1800
log local0. "Set persistence, going to look it up"
set persistInfo [persist lookup uie "JEN2"]
log local0. "I set my universal persistence to: $persistInfo"
}
}
VS without persistence
ltm virtual VS_jenise2 {
destination 1.1.1.2:http
ip-protocol tcp
mask 255.255.255.255
pool pool_jenise
profiles {
http { }
tcp { }
}
rules {
TestLookup
}
source 0.0.0.0/0
source-address-translation {
type automap
}
vs-index 21
}
ltm rule TestLookup {
when HTTP_REQUEST {
log local0. "****************** hi jen!"
set persistInfo [persist lookup uie "JEN2"]
log local0. "****************** here persistInfo is .$persistInfo."
}
}
Here is the output from accessing the first virtual server:
May 3 06:56:21 myLTM info tmm[14401]: Rule /Common/JenPersistence : Set persistence, going to look it up
May 3 06:56:21 myLTM info tmm[14401]: Rule /Common/JenPersistence : I set my universal persistence to: /Common/pool_jenise 2.2.2.2 80
The persistence table shows the entry:
root@(myLTM)(cfg-sync Changes Pending)(Active)(/Common)(tmos) show ltm persistence persist-records
Sys::Persistent Connections
universal JEN2 1.1.1.1:80 2.2.2.2:80 (tmm: 0)
Accessing the second VS shows an empty query result:
May 3 06:56:32 myLTM info tmm[14401]: Rule /Common/TestLookup : ****************** hi jen!
May 3 06:56:32 myLTM info tmm[14401]: Rule /Common/TestLookup : ****************** here persistInfo is ..
Do I need some sort of persistence profile on the second VS to even be able to query the table?
Thanks, Jen

can you try this?
[persist lookup uie "JEN2 any virtual"] 
nitass_89166Noctilucent
e.g.
config root@(ve11c)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual one ltm virtual one { destination 172.28.24.248:80 ip-protocol tcp mask 255.255.255.255 persist { universal { default yes } } pool foo profiles { http { } tcp { } } rules { ruleone } source 0.0.0.0/0 source-address-translation { type automap } vs-index 19 } root@(ve11c)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual two ltm virtual two { destination 172.28.24.249:80 ip-protocol tcp mask 255.255.255.255 pool foo profiles { http { } tcp { } } rules { ruletwo } source 0.0.0.0/0 source-address-translation { type automap } vs-index 20 } [root@ve11c:Active:In Sync] config tmsh list ltm rule ruleone ltm rule ruleone { when HTTP_REQUEST { persist uie [HTTP::path] log local0.

dubdubHi Nitass, I was able to try the "any virtual" option, and it did enable me to see the persistence record from the second VS. Thank you very much for the help! Thanks, Jen
