A site has assigned the ICMP monitor to all nodes and a custom monitor, based on the HTTP template, to a pool of web servers. The HTTP based monitor is working in all cases. The ICMP monitor is failing for 2 of the pool member 5 nodes. All other settings are default. What is the status of the pool members?
A. All pool members are up since the HTTP based monitor is successful.
B. All pool members are down since the ICMP based monitor is failing in some cases.
C. The pool members whose nodes are failing the ICMP based monitor will be marked disabled.
D. The pool members whose nodes are failing the ICMP based monitor will be marked unavailable.
The correct answer is apparently D, but why does the monitor mark the pool members as unavailable instead of disabled?
Ans:---
A BIG-IP administrator can assign a pool member one of the following states:
- Enabled
- Disabled
- Forced offline
whereas in your case it is the system that assign a pool member one of the following states according to his state of health:
- Unavailable
- Available
So to answer to your question, the monitor mark the pool members as unavailable instead of disabled because that the system that detect that monitor fail and therefore it mark it at unavailable...
