Conﬁgure disk devices

After verifying device recognition, conﬁgure the devices on the Windows NT system.

Writing the signatures

The ﬁrst step in conﬁguring the disk devices is to write the signatures on the new devices

using the NT Disk Administrator. You must write a signature on each disk device to

enable the NT system to work with the device online. The 32-bit signature identiﬁes the

disk to the N T system. If the d isk’s TID or LUN is changed the Disk Administrator and

Windows N T fault-tolerant driver will continue to recognize it.

To write th

e signatures on the disk devices:

1. From the Start menu, select:

Programs

→Administra tive Tools (Common)→

Disk Administrator

Awindownotiﬁes you that the Disk Administrator has recognized the new hardware

and will update the system conﬁguration.

2. Click En

ter to continue.

A warning window notiﬁes you that no signature was found on Disk x (the disk

array). Writing a signature is a safe operation and will n ot affect your ability to

access this disk from other operating systems. If you choose not to write a signature,

Clicking Yes writes the host’s 32-bit signature that identiﬁes the disk array. The disk

numbers are assigned sequentially by the adapter and TID/LUN and are displayed

during system start-up.The Disk Administrator window opens to allow you to create

partitions.
