Chapter 4: Configuring a Storage Array 73
Setting the
Controller Clocks
To synchronize the clocks on the controllers with the host, use the
set
storageArray time
command. Run this command to make sure that event time
stamps that are written by the controllers to the Event Log match the event time
stamps that are written to the host log files. The controllers stay available during
synchronization. This example shows the command:
c:\...\sm X \client>smcli 123.45.67.88 123.45.67.89

-c “set storageArray time;”
Setting the Storage
Array Password
Use the
set storageArray
command to define a password for a storage array.
The command has this form:
set storageArray password=” password ”
The
password
parameter defines a password for the storage array. Passwords
provide added security to a storage array to help reduce the possibility of
implementing destructive commands.
ATTENTION Possible data corruption or data loss
– Implementing destructive
commands can cause serious damage, including data loss.
Unless you define a password for the storage array, you can run all of the script
commands. A password protects the storage array from any command that the
controllers consider destructive. A destructive command is any command that can
change the state of the storage array, such as volume creation; cache modification; or
reset, delete, rename, or change commands.
If you have more than one storage array in a storage configuration, each storage array
has a separate password. Passwords can have a maximum length of 30 alphanumeric
characters. You must enclose the password in double quotation marks (“ ”). This
example shows how to use the
set storageArray
command to define a
password:
c:\...\sm X \client>smcli 123.45.67.88 123.45.67.89

-c “set storageArray password=”1a2b3c4d5e”;”
Setting the Storage
Array Host Type
Use the
set storageArray
command to define the default host type. The
command has this form:
set storageArray defaultHostType=( hostTypeName |
hostTypeIdentifier )
The
defaultHostType
parameter defines how the controllers in the storage array
communicate with the operating system on undefined hosts that are connected to the
storage array SAN. This parameter defines the host type only for data I/O activities of
the storage array. This parameter does not define the host type for the management
station. The operating system can be Windows, Linux, or Solaris.
