Hi,
Only now have I been able to act on this problem. My environment is relatively simple: I have two ESXi 6.7 hosts, connected to two ISCSI gateways, using two RBD images.
When this mail started, the workaround was to keep only one ISCSI gateway connected, so it works normally. After the answer that received here that the problem could be in the configuration of VMWare, I reviewed the configuration of both (they are exactly according to Ceph documentation), and rebooted both.
It turns out, now the gateway "ceph-iscsi1" is working. When I turn on "ceph-iscsi2" it appears as "Active / Not optimized" for the two RBD images (before was an Active / Optimized for each image), and if I turn off "ceph-iscsi1" it (ceph-iscs2) remains as "Active / No optimized "and images are unavailable.
Nothing is recorded in the logs. Can you help me?

Your multipathing in ESX is probably misconfigured and you have set it
up for active active, or one host can't see all the iscsi paths either
because it's not logged into all the sessions or because the network is
not up on one of the paths.
