HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

Table 9 NPIV supported limits in vPars and Integrity VM V6.1
Supported limitLimit description
8NPIV HBAs per vPar/VM
16Number of NPIV HBAs per physical HBA
8Number of paths supported per NPIV device
2048Number of LUNs per NPIV HBA
2048Number of NPIV devices per vPar/VM
NOTE: In configurations where multiple NPIV HBAs created from a single physical HBA are used
by different vPars/VMs, all the I/O from these vPars/VMs share a single physical HBA, which
could lead to performance bottlenecks in high I/O scenarios.
For a more balanced performance, HP recommends that you spread NPIV HBAs for vPars/VMs
across multiple physical adapters.
5.3.1 Verifying that the VSP can support NPIV
Before creating a vHBA, check the physical HBAs on the system to verify that they support NPIV.
The fcmsutil command can do this check. Run this command on a VSP Fibre Channel HBA:
/opt/fcms/bin/fcmsutil /dev/fcdX
where X is the instance number of the Fibre Channel HBA and can be obtained from the ioscan
–kfnC fc command:
# ioscan -kfnC fc
