CLI Command Descriptions
NOTE: The CHUNKSIZE switch is only valid with stripesets and raidsets.
The default chunk size for storagesets with less than or equal to nine members is
256 blocks, or 128 kilobytes (K). The default chunk size for storagesets with more
than nine members is 128 blocks or 64K. StorageWorks does not recommend a
chunk size less than 128 blocks (64K).
IMPORTANT: The default chunk size should be used with caution. It is imperative that you
analyze the I/O transfers being used with your application to determine the proper chunk size.
An improper value used as a chunk size may cause serious performance problems with the
subsystem.
Refer to the detailed description of chunk size that is contained in the controller
installation and configuration guide for information regarding recommended
chunk size settings for this application.
DESTROY (default)
NODESTROY
Controls how the metadata on the initialized container is to be handled.
NOTE: The DESTROY and NODESTROY switches are valid only with striped mirrorsets
and mirrorsets.
• Specify NODESTROY to preserve forced error metadata during the
initialization process. Use the NODESTROY switch only when a unit is to be
created from disk drives reduced from mirrorsets. This allows the data on the
container to be accessed by a mirrorset or striped mirrorset unit. The
NODESTROY switch is not valid for RAIDsets, simple stripesets, and
single-disk configurations.
• Specify DESTROY to overwrite user data and forced error flags during the
initialization.
SAVE_CONFIGURATION
NOSAVE_CONFIGURATION (default)
Instructs the controller to save the controller configuration (or not to save the
configuration) to the container being initialized.
The SAVE_CONFIGURATION switch requires only one disk to be initialized with
this option. However, more disks may be used, if desired, for redundancy.
• Specify SAVE_CONFIGURATION to store a copy of the controller
configuration on the container being initialized. A new controller can receive
information from a container containing configuration information saved with
the SAVE_CONFIGURATION switch. If you specify
