Adaptec SCSI RAID Software Reference Guide
{scsi_device}
Specifies the ID for the SCSI device whose freespace you want
to use to create the multilevel array of mirror sets. The size of
this freespace should be greater than or equal to the size of the
first underlying volume set. A SCSI ID consists of a SCSI bus
number (e.g., 0, 1, 2, 3, etc.), SCSI device ID (0 through 15
inclusive), and SCSI device logical unit number (0 through 7
inclusive). See the installation guide for your controller to
determine the number of buses it actually supports.
See the scsi_device section on page 3-7 for more
information on how to specify the SCSI device.
{scsi_device}...
Specifies the IDs for additional SCSI devices whose freespaces
you want to use to create the multilevel array of mirror sets.
There must be sufficient contiguous space available on each
specified device.
The number of SCSI devices you specify must be equal to the
number of single-partition volume sets that make up the
multilevel array of volume sets. The size of the freespace used
is equal to its corresponding underlying volume set.

/io_delay{=integer}
Specifies the number of milliseconds the controller waits
between the I/Os required to create the multilevel array of
mirror sets. If you do not specify this switch, the I/O delay is
always zero (0). The I/O delay value is not preserved between
reboots of the operating system.
/wait{=integer}
Specifies whether to create the multilevel array of mirror sets
synchronously or asynchronously. If you set this switch to
TRUE, the command creates the multilevel array of mirror sets
synchronously and the command prompt does not return until
the mirror-set creation task completes.
If you do not specify this switch, the mirror-set creation starts
asynchronously and the command prompt returns
immediately.
