Unit Object Commands
www.lsi.com/channel/products 71
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 can use this
command as follows:
1 Issue the command (set autodetect=off) to disable automatic detection of
the ports for staggered spinup.
2 Remove the drives from the specified ports if the ports are not empty.
3 Insert (or replace) the drives at the ports specified.
4 Issue the command (set autodetect=on) to enable autodetect of the ports
with the newly inserted drives.
The preceding steps 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.
Unit Object Commands
Unit Object commands provide information and perform actions related to a
specific unit, such as
/c0/u1 (unit 1 on controller 0). You can use unit object
commands for a number of tasks, for example, to see the rebuild status, verify
status, or initialize status of a unit; to start, stop, and resume verifies; to start
and stop rebuilds; to set policies for the unit, and to perform other tasks
related to the unit.
