FRUs That Do Not Require Oracle Solaris Cluster Maintenance Procedures
This section contains the procedures about how to maintain a storage system in a running cluster. Table 3-1 lists these procedures.
Table 3-1 Task Map: Maintaining a Storage System

Note - Most storage arrays are maintained through common array management software. For example, see Sun StorageTek Common Array Manager Software.
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.
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 might change unexpectedly. When you perform a check of the device ID configuration by running the cldevice check command, the following error message appears on your console if the device ID 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 device IDs that report this error, run the cldevice repair command for each affected device.
For specific instructions, see your storage array's documentation.
# luxadm probe
You stopped I/O to these storage arrays in Step 1.
Use this procedure to permanently remove a storage array from a running cluster.
Caution - During this procedure, you lose access to the data that resides on the storage array that you are removing. Back up the data before you proceed. |
For more information, see your Solaris Volume Manager or Veritas Volume Manager documentation.
