Building the Bootable Disk

This procedure assumes that the system is already booted from an existing system hard disk, and that you have already performed a full system backup.

The device path on each system differs, depending on the PCI bus slot, target ID, LUN, etc. The device name shown in this example is for a device on the third PCI bus slot, target ID 130, LUN 0, slice 0.

You must have already completed the steps in the previous sections before attempting to create a bootable disk.

To build a bootable disk, perform the following steps:

1.Determine the amount of disk space used/available on your current boot disk. Use the df command for a listing. For example:

/usr/bin/df -k -l
Filesystem	kbytes	used	avail	capacity	Mounted on
/dev/dsk/c0t0d0s0	2577118	1650245	875331	66%	/
/proc	0	0	0	0%	/proc
fd	0	0	0	0%	/dev/fd
mnttab	0	0	0	0%	/etc/mnttab
swap	1310480	0	1310480	0%	/var/run
swap	1311344	864	1310480	1%	/tmp
/dev/dsk/c0t0d0s7	5135326	114	5083859	1%	/home

This df example shows that the current boot disk is /dev/dsk/c0t0d0s(x). There are two partitions of interest, slice 0 (/) and slice 7 (/home). Slice 0 uses 1.65 GB and has 875 MB free. Slice 7 uses 114 MB and has 5 GB free. Therefore, slice 7 (/home) contains enough disk space to store the temporary saveset files.

If there were not at least 1.7 GB free on this disk, you would need to create a partition on the new bootable disk large enough to hold the largest temporary saveset files plus the largest used space on a partition. In this example, it would be a 3.2 GB (1.6 GB+1.6 GB) partition.

2.Use the format command to create, label, and format partitions on the new bootable disk. These partitions must be able to contain the contents of your temporary saveset files. If you are not familiar with the format command, refer to the Solaris documentation.

WARNING!! Misusing the format command can destroy the data on your current disk drives.
