How to Upgrade Storage Array Firmware
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.
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 scdidadm -c 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 scdidadm -R command for each affected device.
Stop all I/O to the storage arrays you are upgrading.

Apply the controller, disk drive, and loop-card firmware patches by using the arrays' GUI tools.
2
For specific instructions, see the array's online documentation.
Confirm that all storage arrays that you upgraded are visible to all nodes.

How to Remove a Storage Array
Use this procedure to permanently remove a storage array from a running cluster.
This procedure defines Node N as the node that is connected to the storage array you are removing
and the node with which you begin working.
During this procedure, you lose access to the data that resides on the storage array that you

are removing.
If necessary, back up all database tables, data services, and volumes that are associated with each
