How to Upgrade Disk Drive Firmware

Upgrade your disk drive firmware if you want to apply bug fixes or enable new functionality.

Before You Begin

This procedure relies on the following prerequisites and assumptions.

• Your cluster is operational.

• Your nodes are not configured with dynamic reconfiguration functionality.

  If your nodes are configured for dynamic reconfiguration, see the Sun Cluster system administration documentation, and skip steps that instruct you to shut down the node.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.

To perform this procedure, become superuser or assume a role that provides solaris.cluster.read and solaris.cluster.modify RBAC authorization.

1. If the disk drive on which you want to upgrade the firmware is configured as quorum device, add a new quorum device that will not be affected by this procedure. Then remove the old quorum device.

   To determine whether a quorum device will be affected by this procedure, use one of the following commands.

   • If you are using Sun Cluster 3.2, use the following command:

     # clquorum show

   • If you are using Sun Cluster 3.1, use the following command:

     # scstat -q

   For procedures about how to add and remove quorum devices, see the Sun Cluster system administration documentation.

2. If possible, back up the metadevices or volumes that reside in the disk drive.

   For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.

3. Perform volume management administration to remove the disk drive from the configuration.

   For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.

4. Install the firmware.

   For more information about how to install firmware, see the patch installation instructions.

5. Perform volume management administration to add the disk drive back into the configuration.

   For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.
