Example--Applying a Rebooting Patch (Node)
The following example shows the application of a rebooting Sun Cluster patch to a node.
# scrgadm -pv ... RG Name: schost-sa-1 ... # scstat ... Device Group Name: dg-schost-1 ... # scswitch -S -h phys-schost-2 # shutdown -g0 -y -i0 ... ok boot -sx... # patchadd -M /tmp/patches 234567-05 ... # reboot ... # showrev -p | grep 234567-05 # scswitch -z -D dg-schost-1 -h phys-schost-1 # scswitch -z -g schost-sa-1 -h phys-schost-1 |

How to Apply a Rebooting Patch (Cluster and Firmware)
With this procedure, you must first shut down the cluster and boot each node to single-user mode using the boot -sx command, before applying the patch.
Before applying the patch, check the Sun Cluster product web page for any special pre- or post-installation instructions.
Become superuser on any node in the cluster.
Shut down the cluster.
# scshutdown -y -g grace-period "message"
-y Specifies to answer yes to the confirmation prompt.
-g grace-period Specifies, in seconds, the amount of time to wait before shutting down. Default grace period is 60 seconds.
message Specifies the warning message to broadcast. Use quotes if message contains multiple words.
Boot each node into non-cluster single-user mode.
On the console of each node, run the following command.
ok boot -sx
Apply the software or firmware patch.
On one node at a time, run the following command.
# patchadd -M patch-dir patch-id
patch-dir Specifies the directory location of the patch.
patch-id Specifies the patch number of a given patch.
Note - Always defer to the instructions in the patch directory that supersede procedures in this chapter.
Verify that the patch has been installed successfully on each node.
# showrev -p | grep patch-id
After applying the patch to all nodes, reboot the nodes into the cluster.
On each node, run the following command.
# reboot
Verify that the patch works, and that the nodes and cluster are operating normally.
Example--Applying a Rebooting Patch (Cluster)
The following example shows the application of a rebooting Sun Cluster patch to a cluster.
# scshutdown -g 0 -y ... ok boot -sx ... # patchadd -M /tmp/patches 234567-05 (Apply patch to other cluster nodes) ... # showrev -p | grep 234567-05 # reboot |

How to Apply a Non-Rebooting Sun Cluster Patch
Apply the patch to one node in the cluster at a time. When applying a non-rebooting patch, you do not need to first shut down the node receiving the patch.
Before applying the patch, check the Sun Cluster product web page for any special pre- or post-installation instructions.
If this is a data service patch, switch over the affected data service(s) from the node that you will be patching to a backup node, before applying the patch.
# scswitch -z -g resource-group[,...] -h node[,...]
Apply the patch on a single node.
If you switched a data service in Step 2, perform the patch installation on the node from which you switched the data service.
# patchadd -M patch-dir patch-id
patch-dir Specifies the directory location of the patch.
patch-id Specifies the patch number of a given patch.
Verify that the patch has been installed successfully.
# showrev -p | grep patch-id
Verify that the patch works, and that the node and cluster are operating normally.
If you switched a data service to a backup node in Step 2, you can now switch it back to the original primary node.
Repeat Step 3 through Step 5 for the remaining cluster nodes.
Example--Applying a Non-Rebooting Sun Cluster Patch
# patchadd -M /tmp/patches 234567-05 ... # showrev -p | grep 234567-05 |
