Hard Drives
For information about performing a hot-swap operation on a mirrored hard drive,
refer to the
Netra 440 Server System Administration Guide (817-3884-xx) .
The system’s hard drive hot-swap feature enables you to remove a hard drive
without shutting down the operating system or turning off the system power. The
way in which you remove a hard drive depends on the application you are using
and whether you are replacing a drive, adding a new one, or removing a drive
permanently.
When you remove a drive using the hot-swap operation, you need to stop the hard
drive and take it offline to remove the logical software links to the hard drive, and to
reconfigure the file systems so that they now ignore the removed drive. You might
also have to reconfigure your application software to operate without the removed
drive.
Use the
cfgadm
command to remove a Netra 440 server’s internal hard drive using
the hot-swap operation. The following procedure describes the general steps
involved, but your specific device names might be different.
The following procedure assumes that you are accessing the system console by the
default method of connecting to the serial management port (SERIAL MGT) of the
Netra 440 server.
Caution –
Do not hot-swap drives without the correct preparations. The system
supports hot-swapping hard drives, but you must issue a software command before
you remove or install a hard drive.
If a hard drive fails, the enclosure status Service Required LED lights up and a
console message indicates which hard drive failed.
