Description

We have exposed a 4 TB namespace to VMware client using NVME TCP protocol from a Ceph cluster.
Setup works fine till the time ana-reporting & enable-ha are disabled on a subsystem.
But when those are enabled on a ceph cluster to achieve multipathing, device path status turns into standby in VMware.

Setup details -
ceph version - 18.2.2 (531c0d11a1c5d39fbfe6aa8a521f023abf3bf3e2) reef (stable)
Protocol- NVME TCP
Hypervisor: VMware ESXi, 7.0.3, 23307199
nvmeof & nvmeof-cli version - 1.0.0

Is TCP multipathing supported on a Ceph cluster ?

Research direction

No files or tests are named. Start by reviewing the Ceph 18.2.2, NVME TCP, nvmeof 1.0.0, and VMware ESXi 7.0.3 setup described in the issue, then investigate the path-status change with ana-reporting and enable-ha enabled. Done means establishing whether TCP multipathing is supported and documenting the cause or a clear supported configuration.
