Mirrored disk installation

• Configuring the disks into the system.

• Installing the disks.

• Booting the system with the mirrored disk configuration.

• Installing the mirrored disk software with the AUTOINST utility.

Use SYSGEN to configure the mirrored disks into the system. Refer to the System Startup, Configuration, and Shutdown Reference Manual (32650-90042) for more information.

Install the disks according to the appropriate disk installation manual. Use the following guidelines:

Figure 2-1 “Sample Mirrored Disk Configuration” shows how mirrored disks can be connected to the system.

The above example shows four device adapter cards connected to twenty disks (ten mirrored pairs).

Figure 2-2 “Sample Cabinet Installation” shows how twenty disks can be installed next to their partners in eight pack cabinets. Refer to the appropriate disk operating and installation manual for any disk cabling restrictions.

LDEVs 30, 31, 32, and 33 are the disks directly connected to device adapter cards. All of the other disks are chained off those disks.

	NOTE: For quick reference, it is a good idea to draw a map of the mirrored disks with member names and LDEV numbers and to mark which disks are connected to the device adapter cards. This map helps to easily identify the location of each disk.

Boot the system with the mirrored disk configuration group. Refer to the System Startup, Configuration, and Shutdown Reference Manual (32650-90042) for more information about booting the system.

The mirrored disk product is distributed on a magnetic tape. Install the tape using the AUTOINST utility described in the HP3000 MPE/iX Installation and Update Manual (36123-90001).
