Managing Disk Devices

HP-UX version 11.00.01 Configuring Disk Drives 4-3

Managing Disk Devices

The procedures in this section apply to all cases of adding, replacing, moving, and

deleting disk drives.

CAUTION

Although SAM allows you to manage disk devices, do not use SAM for

any of the following procedures (add, replace, move, or delete a disk).

Using SAM might cause the procedure to fail and leave the LVM in an

inconsistent state.

NOTE

This chapter includes procedures for adding, replacing, moving, or

deleting a disk. In general, the only tasks you need to perform are

adding a new disk to an empty slot or replacing a malfunctioning disk

in its current slot. Moving and deleting a disk are rare events. However,

one such situation is when you replace a smaller with a larger disk. In

that case you must first delete the smaller disk and then add the larger

disk. The replacement procedure applies to disks of the same size

(model number) only.

Adding a Disk Drive

Use the following procedure to add a new disk drive to your system:

1. Log in as root.

2. Install the hardware, following instructions provided in the HP-UX Operating

System: Continuum Series 400 Operation and Maintenance Guide (R001H), the

HP-UX Operating System: Continuum Series 400-CO Operation and Maintenance

Guide (R025H), or the HP-UX Operating System: Continuum Series 600 and 1200

Operation and Maintenance Guide (R024H).

3. Configure the device into the system by entering

addhardware

This command updates the ioconfig file, writes the new configuration back

to the boot location, identifies the new disk to the HP-UX operating system,

associates it with its device driver, and creates the character and block device

special (/dev) files required to communicate with the disk. See the

addhardware(1) man page for more information.
