Create a Fibre Channel Remote Boot Disk

Complete the following procedure to create a Fibre Channel boot disk. In this example, the Fibre

Channel drive is /dev/sda.

To create an FC remote boot disk:

1. Copy the boot block from the local drive to the Fibre Channel drive by executing the following

command. Press Ctrl+C to stop the command after it has run for approximately 30 seconds.

dd if=/dev/hda of=/dev/sda bs=64k

2. Invoke fdisk /dev/sda. Partition information is now a copy of the partition information of /dev/hda.

a. Delete the partition information that now appears on /dev/sda and write the disk label

(w command).

b. Use the partition information on /dev/hda to insure that each partition is at least the

same number of blocks as on /dev/hda. Its assumed that the root partition will be consid-

erably larger on /dev/sda:

/dev/sda1 will be PPC PreP Boot type=41

/dev/sda2 will be /boot type=83

/dev/sda3 will be / type=83

/dev/sda4 will be swap type=82

c. While in fdisk, set the partition types by entering t at the command line. Toggle the boot-

able flag on partition 1. Results should be similar to the following:

d. Write the partition table and quit.

3. Create file systems on the Fibre Channel disk:

mkfs /dev/sda2

mkfs /dev/sda3

Note: When the system boots from a storage area network (SAN), during system

initialization the kernel will find the IDE local driver and it will use the local driver to

complete booting; the local drive will then become the boot disk. To avoid this,

remove the internal IDE disk after the remote disk is properly set up.

Note: If your system includes a SCSI drive instead of an IDE drive, replace sda with sdb

and replace hda with sda in the example.
