Solaris

hi I am working with sun solaris 9 and I have 40 GB hard disk and I want to recreate the partition.

1)how can I recreate the partition??
2) how can I take the back-up of my application so that I will not loose the data..

#sudo format

select your disk on which you have to make partition........

format> partition
print - check current status of your disk
modify - to create partition

Select partitioning base:
0. Current partition table (default)
1. All Free Hog
Choose base (enter number) [0]? 1

Part Tag Flag Cylinders Size Blocks
0 root wm 0 0 (0/0/0) 0
1 swap wu 0 0 (0/0/0) 0
2 backup wu 0 - 49149 60.00GB (49150/0/0) 125824000

5 unassigned wm 0 0 (0/0/0) 0
6 usr wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0

Do you wish to continue creating a new partition
table based on above table[yes]?

Okay to make this the current partition table[yes]? yes
Enter table name (remember quotes): new

Ready to label disk, continue? yes

After this we can create the file systems on each slice:

newfs /dev/rdsk/c0t0d0s and so on....

At this point we must create the mount points:

mkdir -p /mount/data (note -p makes the parent directories if they don't exist since




Now change ownership to oracle user for all file systems so oracle database can write to them:

sudo chown oracle:dba /mount/data



Finally, we're ready to edit the vfstab with the new entries:

/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 2
no -


Now we can mount up the file systems:

sudo mount /mount/data

and now he has no OS on his disk!

The only guaranteed way to do this is to take a copy of your more important data and reinstall the OS, doing your relayout as you go along.

You can do this by running a backup to an external disk and then making the changes as listed above and then restoring your OS but in the long run yuor would be better to just reinstall.
