sdiadd(1M)

sdiadd -- hot add mass storage devices to a UnixWare system

Synopsis

/sbin/sdiadd [-n] device

Description

The sdiadd(1M) script is used to hot add a SDI mass storage device (such as a disk or tape drive) to the UnixWare system. It cannot be used to hot add a controller.

Options

sdiadd takes the following option and argument:

-n: Prevents sdiadd from prompting the user or quieting the SCSI bus. It also allows the command to be run outside the console.
device: This required argument specifies the new device you want to add.

Usage

Hot addition/removal provides the ability to add or remove SDI mass storage devices from a running system.

To use this feature, the HBA and target drivers must support hot addition/removal.

Using SCSI hot addition/removal with sdiadd

To add a device to the system:

Choose a SCSI ID for the device, making sure it does not conflict with any on the SCSI bus. Failure to do this correctly will crash the system; this is a hardware limitation that cannot be addressed in software.
Ensure that adding the device to the system will maintain proper SCSI bus termination. Failure to do this correctly will crash the system; this is also a hardware limitation that cannot be addressed in software.
To simplify this problem, never have any termination on a device; instead, use terminators attached to the end of the SCSI bus cable. It is recommended that the device not provide termination power. Most devices have a jumper or switch to disable termpower.
Type /sbin/sdiadd.
Physically attach the device to the SCSI bus.
Press <Enter> to inform sdiadd that the device has been added and that normal SCSI bus operation can resume.

NOTE: If you change the hard disk configuration on your system (for example, you add or replace a hard disk), create new emergency recovery disks. For details, see emergency_disk(1M).
