Warning: you will need to re-install all software and restore user data
from backups after changing the partition layout. Changing partitions
will cause all data on the drive to be lost. Be sure you have the drive
backed up if it contains any user data. Continue? yes
Enter .. when done

注: 8、10号分区不能改变，1号分区是swap区。
二、创建文件系统和文件系统的安装：
硬盘分区结束，创建文件系统并安装，分区才能使用。
1．使用mkfs命令创建文件系统。
DATA #mkfs dks0d5s7 对第5块硬盘的7区创建文件系统
meta-data=dks0d5s7 isize=256 agcount=9, agsize=246909 blks
data = bsize=4096 blocks=2222178, imaxpct=25
= sunit=0 swidth=0 blks
log =internal log bsize=4096 blocks=1000
realtime =none extsz=65536 blocks=0, rtextents=0
unwritten flagging is enabled
2．安装文件系统：
#mount /dev/dsk/dks0d5s7 /home
编辑/etc/fstab文件，加入：
/dev/dsk/dks0d5s7 /home xfs rw,raw=/dev/rdsk/dks0d5s7 0 0
#df -k
Filesystem Type kbytes use avail %use Mounted on
/dev/root xfs 3913932 1651484 2262448 43 /
/dev/dsk/dks0d3s2 xfs 8884320 153000 8731320 2 /aa
/dev/dsk/dks0d5s7 xfs 8884712 160 8884552 1 /home 查看是否安装正确
