Applies to

  • ONTAP 9.14.1P9, 9.16.1P6
  • NVMe/TCP

Issue

  • Admin operations relating to NVMe are failing, e.g. adding an NVMe subsystem host:
::> vserver nvme subsystem host add -vserver TEST_NVME -subsystem TEST -host-nqn nqn.2014-08.org.nvmexpress:uuid:31343550-3939-5a43-4a44-305930304c38
 
Error: command failed: Timeout: Operation "bcomd_nvmf_subsystem_host_mhostCreate_iterator::create_imp()" took longer than 120 seconds to complete [from mgwd on node "test-n1" (VSID: -1) to bcomd at
127.0.0.1]
  • Same when removing a namespace subsytem mapping:

::> vserver nvme subsystem map remove -vserver TEST_NVME -subsystem TEST -path /vol/NVME_DS_01/DS01

Error: command failed: Timeout: Operation "bcomd_nvmf_subsystem_map_mhostRemove_iterator::create_imp()" took longer than 120 seconds to complete [from mgwd on node "test-n1" (VSID: -1) to bcomd at 127.0.0.1]

  • Same when deleting an NVMe/TCP LIF:

::> net int delete -vserver TEST_NVME -lif lif_nvme_25
  (network interface delete)

Error: command failed: Timeout: Operation "vifmgr_virtual_interface_iterator::remove_imp()" took longer than 120 seconds to complete [from mgwd on node "test-n1" (VSID: -1) to vifmgr at 127.0.0.1]
