Device Switches
When you add a disk drive or other storage device to your subsystem,
you can enable the following switches:
n Transportability
n Transfer rate
Transportability
Indicate whether a disk drive is transportable when you add it to your
subsystem:
n NOTRANSPORTABLE disk drives (default) are marked with
StorageWorks-exclusive metadata. This metadata supports the
error-detection and recovery methods that the controller uses to
ensure data availability. Disk drives that contain this metadata
cannot be used in non-StorageWorks subsystems.
Consider these points when using the NOTRANSPORTABLE
switch:
n When you bring non-transportable devices from another
subsystem to your controller subsystem, add the device to your
configuration using the ADD command. Do not initialize the
device, or you will reset and destroy any forced error
information contained on the device.
n When you add units, the controller software verifies that the
disks or storagesets within the units contain metadata. To
determine whether a disk or storageset contains metadata, try
to create a unit from it. This causes the controller to check for
metadata. If no metadata is present, the controller displays a
message; initialize the disk or storageset before adding it.
n TRANSPORTABLE disk drives can be used in non-StorageWorks
subsystems. Transportable disk drives can be used as single-disk
units in StorageWorks subsystems as well as disk drives in other
systems. They cannot be combined into storagesets in a
StorageWorks subsystem.
