1.8 Multiple Sessions
A maximum of 16 CLI sessions can run on a single system simultaneously (including accesses with the
Software role). A session for an exclusive resource may conflict with a GUI session or another CLI session.
When a resource is locked by exclusive access control, the command terminates with an error message. If this
occurs, wait until the GUI session or another CLI session that uses the locked resource completes, and then
execute the command again. Resources can be forcibly released by using the "set clienv-force-unlock"
command. This is useful when a terminal is suddenly disconnected or unexpected errors occur.

Slave Controller Logins

For dual controller ETERNUS DX Disk storage system models, at any given time one of the controllers is the
master and the other the slave. Normal logins are to the master controller, and are able to access all the
normal functions. However, if the master controller becomes inaccessible, a redundant IP address function is
available that allows a (reduced functionality) login to the slave controller. Slave controller login is only
possible if a redundant IP address has been preset, and only some of the "show" commands to check the
status of components are available. It also allows the "change master" command to be used to forcibly swap
the master-slave relationship of the two controllers. This command can only be used from the slave controller.
Commands that are not supported by the current login type will fail with an error message if attempted. For
