How to Partition SunBlade100

Hello,
I'm new to unix world but have been playing with the solaris os lately....I have a sunblade 100 machine with Solaris 10 installed on it. I would like to know the steps to partition my harddisk which is 20gb into three partitions of 7/7/6. Would appreciate if you can guide me through the process.

Here is the output of my df command

Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0t0d0s0 13832667 7751455 5942886 57% /
/devices 0 0 0 0% /devices
ctfs 0 0 0 0% /system/contract
proc 0 0 0 0% /proc
mnttab 0 0 0 0% /etc/mnttab
swap 1816696 1432 1815264 1% /etc/svc/volatile
objfs 0 0 0 0% /system/object
fd 0 0 0 0% /dev/fd
swap 1815600 336 1815264 1% /tmp
swap 1815320 56 1815264 1% /var/run
/dev/dsk/c0t0d0s7 4130286 3572098 516886 88% /export/home
/vol/dev/dsk/c1t0d0/usb20fd:c 1003232 16 1003216 1% /rmdisk/usb20fd

Here is the output of Print Partition

Thanks for all the help.

can any one please guide me through the process or hint me for any documentation...i really really appreciate any help that I can get...Thanks

Re-install the OS, and slice the disk an way you want during the installation process.

Is there no way to make the partitions after the installation of the OS..just curious..I actually want to Install Oracle Database 9i and need a partition...

If you've got a second hard drive, you can mirror each slice to it individually, boot to the secondary hard drive, then reformat the primary hard drive as you want, then mirror each slice back to the resized partitions.

If you want to resize the existing partitions, that would also be an option. You could back up all your data. You would lose data if you change the size of any slice with data on it.

You would still have the same number of partitions but you could shrink down extras that you don't want to a tiny size. Use the format / partition/ modify command.

It would probably be less trouble, tho, to save data to tape or other rma, and then just reload the O/S? Would be cleaner.

Thanks very much. I shall try to modify the existing partitions.

Thanks

Could any one help me with modifying the existing partition option. I dont mind loosing the data as i have installed the OS ...

Thanks in advance
