Upgrading the DS6000 code level

Complete this group of tasks to locate, download, and install code upgrades for your storage unit, DS Storage Manager, and DS CLI. You can perform either a concurrent (DS6000™ has current I/O activity) or nonconcurrent (no current I/O activity on the DS6000) code load.

If you are performing a concurrent code upgrade, you must first ensure that all host paths are available and operating correctly. During a concurrent code upgrade, the storage unit host ports temporarily lose their connections for each processor card when that card is upgraded. Before you begin a concurrent code upgrade, ensure that each host has a path to each processor card to prevent a lost connection between the host and the storage unit. If the host does not have a path to each processor card, the paths from the host to the storage unit are lost during the code upgrade.

Note: While each host port is temporarily unavailable during the code upgrade, I/O operations from a host can cause errors to be logged stating that the path is lost. Error message activity can make the host interface unavailable for other host system administration tasks during the code upgrade.

The DS6000 operates its various components with upgradeable code (or firmware). This code governs the operation of the various parts of the unit, such as the device adapters, host adapters, processor cards, and other advanced function features. As IBM continues to develop and improve this code, code updates will be available to you.

Perform the following steps for each storage unit that is connected to the DS Storage Manager.

Check for firmware updates. Follow the instructions in Checking for code updates (real-time only). If you are not required to upgrade your code, stop here.
To upgrade the code successfully, before you proceed with the code upgrade you must ensure that no alert LEDs are illuminated and that there are no open problems in the problem logs. Correct any problems before you proceed with the firmware upgrade. You can correct problems by performing the steps in either Following a light path to perform unguided service or Performing guided service through the problem log.
Obtain the downloadable files from the DS6000 support Web site. Follow the instructions in Downloading code updates.
Install the code update on your storage unit. Follow the instructions in Installing code upgrades (real-time only). You must perform this step for each storage unit that is managed by your DS Storage Manager before you proceed to the next step.
Upgrade the DS Storage Manager. Begin the installation of the new DS Storage Manager by completing one of the following sets of steps:
- If you are installing from the ZIP file bundle, follow these steps:
  1. Extract the DS Storage Manager ZIP folder that is located in the file path where you extracted the ZIP file bundle information.
  2. Navigate to the folder that you just extracted and run setup.exe. You can perform the upgrade using either the graphical mode or silent mode. See Upgrading the DS Storage Manager on a Windows operating system using the graphical mode or Upgrading the DS Storage Manager on the Windows operating system in unattended (silent) mode for the steps. When the installation is complete, a prompt to restart might be displayed. If possible, do not restart at this time. You will perform a restart after you install the DS CLI upgrade.
- If you are installing from the ISO image that you used to create an installation CD, insert the CD and navigate to the DS Storage Manager installation files and run setup.exe. You can perform the upgrade using either the graphical mode or silent mode. See Upgrading the DS Storage Manager on a Windows operating system using the graphical mode or Upgrading the DS Storage Manager on the Windows operating system in unattended (silent) mode for the steps. When the installation is complete, a prompt to restart might be displayed. If possible, do not restart at this time. You will perform a restart after you install the DS CLI upgrade.
Perform the following steps to upgrade the DS CLI:
1. Begin the installation of the new DS CLI by completing one of the following sets of steps:
  - If you are installing from the ZIP file bundle, follow these steps:
    1. Extract the DS CLI ZIP folder that is located in the file path where you extracted the ZIP file bundle information.
    2. Navigate to the folder that you just extracted. To install using graphical mode, run the file setupwin32.exe. To install using console mode, run the file setupwin32console.exe.
  - If you are installing from the ISO image that you used to create an installation CD, insert the CD and navigate to the DS CLI installation files. To install using graphical mode, run the file setupwin32.exe. To install using console mode, run the file setupwin32console.exe.
2. Follow the instructions for upgrading the DS CLI. See Installing the DS CLI using the graphical mode or Installing the DS CLI using the console mode to perform the upgrade using either the graphical mode or console mode.
If you have not already done so, restart your management console.
After the DS Storage Manager is installed, use Storage units — Main page to verify that you can view the status of the storage complex and its associated logical configuration. In the navigation, select Real-time manager > Manage hardware > Storage units. On the Storage units - Main Page, select the appropriate storage unit.
Ensure that no alert LEDs are illuminated and that there are no open problems in the problem logs. Correct any problems. You can correct problems by performing the steps in either Following a light path to perform unguided service or Performing guided service through the problem log.

If you are setting up the DS Storage Manager, return to Setting up the DS Storage Manager and complete the rest of the steps.
