Answer

nvmf.spdk.err: NVMe/TCP controller limits reached on this node. Queue slots provisioned 69568, additional queue slots requested:128, currently supported queue slots:69632.
No more NVMe connects via NVMe/TCP LIFs on this node are allowed.

  • If the customer is having a large NVMe/TCP or NVMe/FC configuration, which breaches the NVMe/TCP or NVMe/FC limits published in HWU, then it will result into over provisioning of NVMe object.
