Hi,
the two boxes are identical models running the same software release (10.0.1 B378.0 with HF3). As I understand it we have a fairly bog standard high availability setup (active/standby).
I was just about to force a failover to the standby unit and thought I would just check to see if it all looked ok and now the pool that was using the external monitor is flagged as down. If I run the script manually it reports the remote system as up. This is very confusing.
I tried restarting the bigd service on the standby unit and it made no difference. The LTM log is reporting that it thinks the members in the pool are down
Mar 18 10:38:52 local/bigip-u2 notice mcpd[1672]: 01070638:5: Pool member nnn.nnn.nnn.nnn:443 monitor status down.
Mar 18 10:38:52 local/tmm err tmm[2485]: 01010028:3: No members available for pool Test_HM
Mar 18 10:43:20 local/bigip-u2 notice root: -bash ==> /usr/bin/bigstart restart bigd
Mar 18 10:43:20 local/bigip-u2 notice mcpd[1672]: 01070410:5: Removed subscription with subscriber id BIGD_Subscriber
I'll reboot the standby unit and see if there is any change from a fresh reboot.
