Changing cluster passwords using the CLI

You can use the command-line interface (CLI) to change the superuser and service passwords.

Passwords only affect the SAN Volume Controller Console that accesses the cluster. To restrict access to the CLI, you must control the list of SSH client keys that are installed on the cluster.

Perform the following steps to change the superuser and service passwords:

Issue the following command to change the superuser password:
```
svctask chuser -password superuser_password superuser
```
Where superuser_password is the new superuser password that you want to use.
Issue the following command to change the service password:
```
svtask chcluster -servicepwd service_password
```
Where service_password is the new service password that you want to use.
