Chapter 2. CLI Syntax Reference
58 3ware Serial ATA RAID Controller CLI Guide
autodetect=on|off enables or disables automatic detection of drives on the
controller’s ports for staggered spin-up.
disk=<p:-p>|all specifies one or many disks (that is, drives or ports). If a port
is empty (no drive is inserted), this feature is disabled for that port and its port
number is shown. The example below shows that autodetect has been set to
off to initiate staggered spin-up during hot-swapping, where port 3 was empty
and ports 5 and 6 had drives inserted.
Example:
//localhost>> /c0 set autodetect=off disk=3:5-6
Setting Auto-Detect on /c0 to [off] for port [3] and for disk
[5,6]... Done
If “disk=all,” then all of the drives or ports for that controller are specified.
For example:
//localhost>> /c0 set autodetect=off disk=all
Setting Auto-Detect on /c2 to [off] for all disks/ports... Done.
Usage Scenario:
If you are hot-plugging a large number of drives at the same time and are
concerned that you might overload the power supply, you might use this
command as follows:
1 Issue the command (set autodetect=off) to disable automatic detection of
the ports for staggered spin-up.
2 If the ports are not emply, pull the drives out of the specified ports.
3 Insert (or replace) the drives at the ports specified.
4 Issue the command (set autodetect=on) to enable auto detect of the ports
with the newly inserted drives.
The preceding steps would spin up the newly inserted drives in a staggered
manner. Please note that the command takes longer for ports that do not have
drives inserted, since the controller allows time for the empty ports to
respond.

start mediascan
This command applies only to 7000/8000 controllers. For 9000 series
controllers, use the verify command.
This command provides media scrubbing for validating the functionality of a
disk, including bad block detection, remapping, and so forth. The command
starts a media scan operation on the specified controller /cx.
