Ready to label disk, continue? yes

Note that the default partition layout when using the Automatic mode is of the form,
partition 0: ~128MB
partition 1: ~128MB
partition 2: entire disk
partition 6: partition 2 - (partition 0 + partition 1)
partitions 3,4,5,7: empty
NOTE: You may modify the partition table by entering “partition” at the format menu prompt
level. Remember to label the disk again after any changes to the partition table are made.
Format
places an entry for the RAID Array in the /ETC/FORMAT.DAT file and the label
command stores the information on the RAID Array. More details about the creation of
FORMAT.DAT entries may be found in the Sun Solaris 2.x Adding and Maintaining
Peripherals Manual.
NOTE: Although the format command will create an HSG60 disk entry in the format.dat file, do
not try to reuse this definition. Always use type 0 to allow Solaris to retrieve the correct logical
geometry for the LUN you are formatting.
File System Creation and Tuning
Before the new LUN can be used by the system, a new filesystem must be created on each
partition that will be mounted. The
newfs command is used to create filesystems, and the
tunefs command is used to modify existing filesystems. For more information, refer to the
man pages for the
newfs and tunefscommands.
■ To create a new filesystem, use the following command:
# newfs -C128 -d0 /dev/dsk/c1t0d0s2
This will create a filesystem on partition 2 of the device. Partition 2 usually defaults to
the entire device.
■ To modify an existing filesystem use:
# tunefs -a128 -d0 /dev/dsk/c1t0d0s2
These commands set maxcontig to 128 and rotational delay to 0. These recommendations
may not optimize your system performance so you may want to experiment with other
values.
