Art method is as follows：
S101：The cluster of the storage cluster interior joint is shared into information to compile in the form of dynamic link library；
Cluster shares the storage cluster status information that information is shared between all nodes in storage cluster, logic
On may be considered with a status information.
After compiling, cluster is shared information and existed in the form of dynamic link library, and dynamic link library is relatively independent, in privately owned shape
Dynamic load when state information is run.And when privately owned status information upgrades, cluster shares information as dynamic link library
Normal work can be continued.
Further, before cluster state information is compiled, a upgrade installation package can be first built, by the update
The configuration node for passing in the storage cluster and being responsible for user mutual is wrapped, to prepare to start to upgrade.Can in upgrade installation package
Information and privately owned status information are shared with the cluster including node, there can also be Lun relevant information etc..
S102：Upgrade the privately owned status information of the node；
Escalation process is typically the task that the node that surrounding cooperates takes over node to be upgraded, is upgraded in node to be upgraded
After the completion of return to its task.In this application, task is mainly that cluster shares information and privately owned status information, naturally it is also possible to is
Other information present in node.
Before the privately owned status information of upgrade node, a judgment step can be increased, for judging the shared letter of cluster
Whether breath compiles completion.If compiling does not complete, recompilate or continue to compile the shared information of cluster.If compiling is all
Complete, then the privately owned status information of upgrade node.It can not certainly judge, but if cluster shares information and do not compile completion
With regard to the privately owned status information of upgrade node, cluster state confusion is easily caused.
In addition, because the quantity of storage cluster interior joint is quite big, these nodes can be grouped or subregion upgrades.
Such as with each two node or every one group of three nodes can be grouped simultaneously label, then upgrade every group of corresponding section by label order
Point.Can certainly be other packet modes, the application is not construed as limiting at this to block form method.To in storage cluster
After node is grouped, it can be upgraded by group.The privately owned status information of node in every group all upgrades completion
Carry out the privately owned status information upgrading of next group of node again afterwards.

Before level, in order to avoid the confusion of escalation process, all nodes in storage cluster can be divided simultaneously by two one group of nodes
Label, then in order of numbers upgrade the privately owned status information of every group of corresponding node.Corresponding technical scheme is as follows：
S201：The cluster of the storage cluster interior joint is shared into information to compile in the form of dynamic link library；
S202：All nodes in the storage cluster divide simultaneously label for one group by each two node；
Here two nodes can be adjacent node, can also be functionally similar node.Packet is to deposit
Accumulation will not cause confusion because of upgrading so that the upgrading progress of different nodes is different.After packet, system is according to label
Order is upgraded successively, is not in that respective nodes are missed, is improved the efficiency of upgrading.
S203：Upgrade the privately owned status information of every group of corresponding node by label order；
There are two nodes, for example, node A and node B, node A to be opened after giving the business of itself to node B in every group
Begin upgrade the privately owned status information of itself, treat node A upgrading complete posterior nodal point B its business is returned into node A, posterior nodal point B
The node A that the business of itself is given after upgrading is upgraded again along these lines, completes the collaboration upgrading between two nodes.
Therefore, it is optimal packet mode that two nodes, which are one group, and three nodes or more node easily upgrades when being one group of upgrading
When business handing-over confusion, unnecessary trouble is brought to escalation process.
S204：After the completion of the privately owned status information upgrading corresponding to all nodes, while upgrade all described
The cluster of node shares information.
