The following steps illustrate how to create a Solaris partition and modify the slices.
Make sure you back up any data before you perform this task.
# fdisk device
# prtvtoc device
Make sure each slice starts on a cylinder boundary. For example, slice 1 starts at 822280000 bytes, which is the cylinder size in bytes multiplied by 1000.
For more information, see the –s option description in the rmformat(1) man page.
# rmformat -s slice-file device
# prtvtoc device
In the following example, slices are created on the device c5t0d0s2. The slice file myslice has been created with the following content:
slices: 0 = 0, 5GB, "wm", "home" : 1 = 8225280000, 6GB : 2 = 0, 44GB, "wm", "backup" : 6 = 16450560000, 15GB
The file will be used when creating the new slices.
# fdisk /dev/rdsk/c5t0d0s2
No fdisk table exists. The default partition for the disk is:
a 100% "SOLARIS System" partition
Type "y" to accept the default partition, otherwise type "n" to edit the
partition table.
yThe current partition is accepted and will not be modified.
