Configurations and Operations After an HBA Replacement (in Windows)

Configurations and Operations After an HBA Replacement (in Windows)

This section describes how to configure the HBA on the storage system and the host to make it work correctly after replacing the HBA of a Windows host.

Preparing for Configuration (in Windows)

Before configuring the new HBA, you must finish preparatory work such as backing up host multipath and disk information and checking the storage device's running status to ensure that the space configuration can be successfully implemented.

Prerequisites
  • The UltraPath software has been installed on the host.
  • The old HBA of the host has been replaced.
Procedure
  1. Back up UltraPath and disk information.

    1. Run upadm show vlun and upadm show path to view and back up the UltraPath status information.
    2. Back up disk information.
      1. Log in to the Windows Server 2008 application server as an administrator.
      2. Press Windows+R (if the operation is performed remotely, perform it in full screen mode) to open the Run dialog box.
      3. Type diskmgmt.msc and press Enter.
      4. On the Disk Management page that is displayed, view the host disk information.
    3. Back up HBA information.
    • If the fcinfo software is installed on the host, do the following:
      1. Press Windows+R to open the Run dialog box.
      2. Type cmd and press Enter.
      3. In the command window that is displayed, run fcinfo to view the HBA information.
    • If the fcinfo software is not installed on the host, do the following:
      1. Press Windows+R to open the Run dialog box.
      2. Type devmgmt.msc and press Enter to open the Device Manager page.
      3. Select Storage controllers and double-click Fibre Chanel Adapter. On the Attribute page, view the vendor and version information.

  2. Check the storage system status. If there are alarms, clear them and then proceed to the next step.
  3. On the storage system, export the storage system configuration data.

    1. Log in to the CLI of the storage system using PuTTY.
      NOTE:

      The default user name and password are admin and Admin@storage respectively.

    2. Run export running_data to export and save the current configuration file.

  4. (Optional) If online replacement is used, you need to delete path information.

    • If the HBA is replaced due to a failure, do the following:
      1. Run upadm show path to check whether the path status of the faulty HBA is Fault. If the path status is Fault, run upadm clear obsolete_path path_id=? to delete the faulty path. Specify the path whose status is Fault using its path_id.
      2. Run upadm show iostat array_id=? to monitor the load balancing of paths. Specify the storage device using the array_id parameter.

        If I/Os are evenly distributed in the remaining paths and there are no errors after 30 seconds, press Ctrl+C to exit.

      3. Run upadm show path to show UltraPath status information.

        The information about the deleted paths should not appear in the execution result.

    • If the HBA is replaced proactively, do the following:
      1. Run upadm show path and upadm show vlun to show UltraPath status information.
      2. Run upadm set pathstate=disable to disable all paths connected to the old HBA. Specify the path to be disabled using its path_id.
      3. Run upadm show iostat array_id=? to monitor the load balancing of paths. Specify the storage device using the array_id parameter.

        If I/Os are evenly distributed in the remaining paths and there are no errors after 30 seconds, press Ctrl+C to exit.

      4. Run upadm show path to show UltraPath status information.

        In the execution result, the states of all paths connected to the old HBA are Disable.

  5. Check whether the new HBA is compatible with the storage system.

    1. Press Windows+R to open the Run dialog box.
    2. Type devmgmt.msc and press Enter to open the Device Manager page.
    3. Select Storage controllers and double-click Fibre Chanel Adapter. On the Attribute page, view the vendor and version information.

  6. Check the host running status.

    1. Check whether any error exists on the host.
      1. Press Windows+R (if the operation is performed remotely, perform it in full screen mode) to open the Run dialog box.
      2. Run eventvwr.msc and devmgmt.msc and press Enter.
      3. In the Event Viewer and Device Manager windows, check whether any error exists on the host. If there are errors, remove them and then proceed to the next step.
    2. Check disk path status.
      1. Run upadm show vlun to query the status of all vLUNs. Confirm that the status of all vLUNs is Normal.
      2. Run upadm show path to check whether the system path status is Normal. If the status of a path is Degrade, check the path connection status on the storage device.

  7. On the switch, check whether the zoning of the new HBA is complete.

Configurations and Operations (in Windows)

Prerequisites
  • The old HBA has been replaced and the new HBA has been correctly installed.
  • The WWNs of the old and new HBAs have been obtained.
  • UltraPath has been installed on the application server.
Procedure
  1. On the storage system, replace the old WWN.

    1. Run show initiator initiator_type=FC to view the connection status between the HBA and the storage device and obtain the ID of the host to which the old HBA belongs.
       
           WWN                 Running Status        Free       Alias      Host ID         Multipath Type 
           ----------------- ------------------- -----      -------    ----------      ------------------ 
           100000000000*       Online                Yes        --         --              Default
    2. Run remove host initiator initiator_type=FC to remove the WWN of the old HBA. Specify the WWN of the old HBA using the wwn parameter.
    3. Run add host initiator host_id=? initiator_type=FC wwn=? to add the new WWN to the host. Specify the host and WWN of the new HBA using the host_id and wwn parameters.
    4. Run show initiator initiator_type=FC. If in the command output, the WWN status of the new HBA is not Free, then the replacement is successful.

  2. Scan for disks on the host.

    1. Press Windows+R (if the operation is performed remotely, perform it in full screen mode) to open the Run dialog box.
    2. Type devmgmt.msc and press Enter.
    3. In the Device Manager window that is displayed, click View and select Show hidden devices.
    4. Right-click Disk Drives > Scan for hardware changes. The system will scan for disks automatically.
    5. Check whether the number of newly generated UltraPath_Disks is the same as that of mapped LUNs. If they are not the same, check the LUN mapping and path connection status on the storage device.
    6. Check whether the number of newly generated SCSI disks (SCSI Disk Devices on the Huawei storage device) is an integral multiple of the number of system paths. If no, check the LUN mapping and path connection status on the storage device.
    NOTE:

    You can run upadm show vlun to query the number of system paths.

  3. Run upadm show iostat array_id=? to monitor the load balancing of paths. Specify the storage device using the array_id parameter.

    If I/Os are evenly distributed in all paths and there are no errors after 30 seconds, press Ctrl+C to exit.
