Checking the Driver Version of the Host HBA

Checking the Driver Version of the Host HBA

If the driver of a host HBA is outdated, the following issues may occur, especially in light-load, 100% hit ratio, and bandwidth-sensitive scenarios: The HBA splits large I/Os; The default concurrency capability is insufficient; The I/O latency increases.

Windows Hosts

Open Server Manager. In the device list, select the desired HBA. On the device property page, click the Driver tab to view the driver version.

Linux Hosts

  1. Run lsscsi to query the channel IDs corresponding to the HBA.

    linux-ob3a:~ # lsscsi

    [6:0:0:6]    disk    HUASY    XXXXXX           2105  -        
    [6:0:0:7]    disk    HUASY    XXXXXX           2105  -        
    [6:0:1:0]    disk    HUASY    XXXXXX           2105  -

    [6:0:1:6]    disk    HUASY    XXXXXX           2105  -        
    [6:0:1:7]    disk    HUASY    XXXXXX           2105  -            

    In the preceding command output, the channel IDs corresponding to the HBA are 5 and 6.

  2. Run cd to go to the corresponding host directory.

    linux-ob3a:~ # cd /sys/class/scsi_host/host5 
    linux-ob3a:/sys/class/scsi_host/host5 # ls 
    84xx_fw_version  cmd_per_lun     driver_version    fw_state    isp_id      model_name           optrom_fcode_version    phy_version        prot_guard_type    sg_tablesize    thermal_temp     unique_id            zio_timer

  3. Run cat to query driver_version.

    linux-ob3a:/sys/class/scsi_host/host5 # cat driver_version 
    8.04.00.13.11.3-k

Follow-up Procedure

If the HBA driver is outdated, update it to the latest version.
