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.
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
scdidadm -c
command, the following error message appears on your console if
the device ID changed unexpectedly.

, device may have been replaced.
To fix device IDs that report this error, run the
scdidadm -R
command for each
affected device.
1. Stop all I/O to the storage arrays you are upgrading.
2. Apply the controller, disk drive, and loop-card firmware patches.
For the list of required patches, see the
Sun StorEdge 6120 Array Release Notes
. 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 6020 and 6120 Array System Manual
.
3. Confirm that all storage arrays that you upgraded are visible to all nodes.

How to Remove a Single-Controller Configuration
Use this procedure to permanently remove a storage array from a running cluster. This
storage array resides in a single-controller configuration. This procedure provides the
flexibility to remove the host adapters from the nodes for the storage array that you
are removing.
This procedure defines
Node A
as the node with which you begin working.
Node B
is
another node in the cluster.
