Querying HBA Priorities

Querying HBA Priorities

After a host identifies a newly installed HBA, you can view properties of the HBA on the host. The method of querying HBA information varies with operating system versions.

Versions Earlier than VMware ESXi 5.5

The command for viewing the HBA properties varies according to the HBA type. The details are as follows:

  • QLogic HBA

    The command syntax is as follows:

    cat /proc/scsi/qla2xxx/N

    The command return provides information such as the HBA driver version, topology, WWN, and negotiated rate.

  • Emulex HBA

    The command syntax is as follows:

    cat /proc/scsi/lpfcxxx/N

    The command return provides information such as HBA model and driver.

  • Brocade HBA
    cat /proc/scsi/bfaxxx/N

VMware ESXi 5.5 and Later Versions

In VMware ESXi 5.5 and later, the /proc/scsi/ directory is empty. Run the following command to query HBA information:

~ # esxcli storage core adapter list
HBA Name  Driver      Link State  UID                                   Description

You can run the following command to obtain more HBA details:
