How To Upgrade Storage Array Firmware When Using Mirroring - Sun Microsystems StorEdge 3900 Series Manual

a. Replace the component.
Refer to your hardware documentation for any component-specific instructions.
b. Fix the volume manager error that was caused by the failed data path.
c. (Optional) If necessary, return resource groups and device groups to this
node.
You have completed this procedure.
2. Determine the resource groups and device groups that are running on Node A.
# scstat
3. Move all resource groups and device groups to another node.
# scswitch -s -h from-node
4. Replace the node-to-switch component.
Refer to your hardware documentation for any component-specific instructions.
5. (Optional) If necessary, return the resource groups and device groups that you
identified in
# scswitch -z -g resource-group -h nodename
# swswitch -z -D device-group -h nodename

How to Upgrade Storage Array Firmware When
Using Mirroring
Use this procedure to upgrade out-of-date controller firmware, disk drive firmware, or
unit interconnect card (UIC) firmware. This procedure assumes that your cluster is
operational. This procedures defines Node A as the node on which you are upgrading
firmware. Node B is another node in the cluster.
Perform this procedure on one storage array at a time. This procedure
Caution –
requires that you reset the storage arrays that you are upgrading. If you reset more
than one storage array at a time, your cluster loses access to data.
1. On the node that currently owns the disk group or diskset to which the mirror
Steps
belongs, detach the storage array logical volume. This storage array is the storage
array on which you are upgrading firmware.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or
VERITAS Volume Manager documentation.
2. Apply the controller, disk drive, and UIC firmware patches.
Step 2 to Node A.
