How to Remove a Disk Drive Using the
Hot-Plug Operation
The system's disk hot-plug feature enables you to remove a disk drive without
shutting down the operating system or turning off the system power. The way in
which you remove a disk 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-plug operation, you need to stop the disk
drive and take it offline to remove the logical software links to the disk 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 Sun Fire V440 server's internal disk drive
using the hot-plug 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
Sun Fire V440 server.
Caution – Do not hot-plug drives without the correct preparations. The system
supports hot-plugging disk drives, but you must issue a software command before
you remove or install a disk drive.
Before You Begin
If a disk drive fails, the system status Service Required LED will light and a console
message will indicate which disk drive failed.
If you have not configured the system with two boot disks, you cannot hot-plug a
single boot disk. You can only hot-plug the boot disk when you have configured a
two-disk mirror of the boot disk for hot-plugging. If the system is configured with a
boot disk and data disks, you can hot-plug the data disks, but not the boot disk. For
more information on disk mirroring, see:
