Maintaining Storage Systems

This section contains the procedures for maintaining a storage system in a running cluster. Table 1-2 lists these procedures.

Table 1-2 Task Map: Maintaining a Storage System

The following is a list of administrative tasks that require no cluster-specific procedures. See the Sun StorEdge 6320 System Reference and Service Manual for the following procedures.

• Adding a disk drive.

• Replacing a failed disk drive.

• Removing a disk drive.

• Replacing an Ethernet cable.

• Replacing an Ethernet hub in a cabinet.

• Replacing the power cable on the storage array.

• Replacing a Power and Cooling Unit (PCU).

• Replacing a storage service processor.

• Replacing a storage service processor accessory tray.

• Replacing a service processor panel.

• Replacing a USB relay panel.

• Replacing a USB flash disk.

• Extending a dual-controller configuration.

• Removing a dual-controller configuration.

• Replacing a chassis.

• Replacing a controller.

• Replacing a storage array-to-switch component in a dual-controller configuration.

  A storage array-to-switch component includes all of the following components.

  • Fiber-optic cable that connects an FC switch to a storage array

  • FC switch GBIC or an SFP that connects an FC switch to a storage array

  • FC switch that connects an FC switch to a storage array

  • FC switch power cord

  • Interconnect cables that connect two storage arrays

  • Interconnect cards

How to Upgrade Storage Array Firmware

Note - When you upgrade firmware on a storage device or on an enclosure, redefine the stripe size of a LUN, or perform other LUN operations, a device ID (DID) might change unexpectedly. When you perform a check of the DID configuration by running the scdidadm -c command, the following error message appears on your console if the DID changed unexpectedly.

 device id for nodename:/dev/rdsk/cXtYdZsN does not match physical 
device's id for ddecimalnumber, device may have been replaced.

To fix DIDs that report this error, run the scdidadm -R command for each affected device.

Use this procedure to upgrade storage array firmware in a running cluster. Storage array firmware includes controller firmware, unit interconnect card (UIC) firmware, EPROM firmware, and disk drive firmware.

1. Stop all I/O to the storage arrays you are upgrading.

2. Apply the controller, disk drive, and UIC firmware patches.

   For the list of required storage array patches, see the Sun StorEdge 6320 System Reference and Service Manual. For the procedure about how to apply firmware patches, see the firmware patch README file. For the procedure about how to verify the firmware level, see the Sun StorEdge 6320 System Reference and Service Manual. For the procedure about how to reset a storage array, see the Sun StorEdge 6320 System Reference and Service Manual.

3. Confirm that all storage arrays that you upgraded are visible to all nodes.

4. Restart all I/O to the storage arrays. You stopped all I/O to these storage arrays in Step 1.
