NimbostratusGTM WideIP status 'Available' while associated LTM Virtual Server status is 'Unknown'
I have a GTM WideIP configured with one pool and one pool member (LTM Virtual Server). There are no additional GTM health monitors configured on the WideIP, Pool, Pool Member, or GTM Virtual Server. The associated LTM Virtual Server does not have a health monitor associated either. I'm curious why the status of the GTM WideIP shows 'Available' and not 'Unknown'. GTM and LTM Configuration attached... gtm wideip u19.ite.xxxxxxxxx.com { ipv6-no-error-response enabled pools { u19.ite.xxxxxxxxx.com { order 0 } } }

Greetings,
I'm unable to reproduce this status. My DNS/GTM shows:
Status Availability : offline State : enabled Reason : No enabled pool members availablePerhaps some info from one level lower; can we see the server object hosting the odd virtua and is it the LTM? There could be a number of possiblities here. Can we see:
tmsh show gtm iquery
Lastly, big3d does get stuck sometimes when doing lots of config work. You could try:
bigstart restart big3d
Thanks!

Can you please tell us if the LTM-yyylbz1a-b is added as generic host or bigip. What is the monitor associated for this server LTM-yyylbz1a-b. For some reason, the pool is marked UP, either it has tcp monitor.
BRUCE_A_NOLAN_1LTM-yyylbz1a-b is server object (not Generic Host) added with the gtm_add script. Its being monitored through iQuery.

an unknown LTM status is considered available on GTM. As soon as you add a monitor (assuming you are using GTM's bigip server monitor only) to your LTM pool, it'll follow the conventions you are used to for LTM.
