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.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.
# 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 rmformat(1).
# 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.
