NPIV/NPV in UCS - vHBA -

[claudedube]

Hi
The NPIV/NPV in UCS blade is not properly configured, the UCS blades are B200 M5 series
The SAN storage is provided through MDS9706 fabric and the NPIV protocol is able on MDS fabrics and working for Oracle virtual machine and AIX/vios environments

The storage is provided through MDS9706 fabric, connected through UCS FI, and the UCS blades are booted on SAN and installed on Red Hat virtualization version 7.7 and it's properly working.

However, the 4 provided HBA are not virtualization capable, so how these 4 HBA ports can be enabled for supporting virtulization capable?

Thanks, Claude

virsh nodedev-list --cap scsi_host
scsi_host0
scsi_host1
scsi_host2
scsi_host3

virsh nodedev-list --cap vports

Discovery

Discovery of HBA(s) capable of NPIV is provided through the virsh command "virsh nodedev-list --cap vports"
which will return a list of scsi_host's capable of generating a vHBA.
These scsi_host's will be described as the parent. If no HBA is returned, then the host configuration should be checked.

It does work on RedHat powerPC linux, it looks like there is a setting missing on UCS bios.

What release notes did you see that capability confirmed from (i.e. where does it say VIC supports nested NPIV in RHEL/KVM)?

I know that question comes up from time to time for ESXi, but know that is not supported currently...

Hi Kirk,

I'm sorry for delay, Red Hat virtualization documentation for creating vHBA for a host guest.

#
# Procedure 13.10. Creating a vHBA  subsection : 13.2.3.8. vHBA-based storage pools using SCSI devices
#

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/storage_pools#storage_pool_params_iSCSI-based_NPIV

vHBA works on Red Hat Virtualization version 4.3 installed IBM Power System L922, npiv technology is used for providing LUN directly on host guest.

I still believe that there is a switch is not on UCS/blade or such.

Thanks, Claude
