There are other commands that can help you learn about your storage subsystem. To see a list of the
commands, see Chapter 3, “Script Commands,” on page 3-1. These commands are organized by the
storage subsystem activities that the commands support, such as logical drive commands, host
commands, enclosure commands, and others.
Clearing the Configuration
If you want to create a completely new configuration on a storage subsystem that already has an existing
configuration, use the
clear storageSubsystem configuration
command. This command deletes all of the
existing configuration information, including all of the subsystems, logical drives, and hot spare
definitions from the controller memory.
Attention: Possible damage to the storage subsystem configuration – As soon as you run this
command, the existing storage subsystem configuration is deleted.
The command takes this form:
c:\...\...\client>smcli 123.45.67.89 -c “clear storageSubsystem configuration;”
With controller firmware 7.xx.xx.xx and higher, this command supports two parameters that you can use
to limit the amount of configuration information removed:
v all
– Removes the entire configuration of the storage subsystem, including security information and
identification information. Removing all of the configuration information returns the storage subsystem
to its initial state. (This is what the command will assume if no parameters are specified.)
v subsystems
– Removes the logical drive configuration and the subsystem configuration, but leaves the
rest of the configuration intact.
Note: With controller firmware earlier than 7.xx.xx.xx,, there are no parameters. The default is the action
described for the all parameter.
If you want to create new subsystems and logical drives within the storage subsystem, you can use the
clear storageSubsystem configuration
command with the
subsystems
parameter to remove existing
subsystems in a pre-existing configuration. This action destroys the pre-existing configuration. Use the
clear storageSubsystem configuration
command only when you create a new configuration.
Using the Auto Configure Command
The
autoConfigure storageSubsystem
command creates the subsystems on a storage subsystem, the
logical drives in the subsystems, and the hot spares for the storage subsystem. When you use the
autoConfigure storageSubsystem
command, you define these parameters:
v
The type of disk drives (Fibre, SATA, SAS)
v The RAID level
v
The number of disk drives in an subsystem
v
The number of subsystems
v
The number of logical drives in each subsystem
v
The number of hot spares
v
The size of each segment on the disk drives
v
A read ahead multiplier
