Problems with partitions

UNIX Solaris
1

Hi. I newbie in solaris.

I have server T2000 with 2 disk on raid.

I have partitions:

Part      Tag    Flag     Cylinders         Size            Blocks
  0       root    wm     825 -  3916       15.00GB    (3092/0/0)   31464192
  1       swap    wu       0 -   824        4.00GB    (825/0/0)     8395200
  2     backup    wm       0 - 14086       68.35GB    (14087/0/0) 143349312
  3 unassigned    wm    3917 -  7008       15.00GB    (3092/0/0)   31464192
  4 unassigned    wm       0                0         (0/0/0)             0
  5 unassigned    wm       0                0         (0/0/0)             0
  6 unassigned    wm       0                0         (0/0/0)             0
  7 unassigned    wm       0                0         (0/0/0)             0

I must have partition more then 20gb. I try to increase partition#3:

partition> 3
Part      Tag    Flag     Cylinders         Size            Blocks
  3 unassigned    wm    3917 -  7008       15.00GB    (3092/0/0)   31464192

Enter partition id tag[unassigned]:
Enter partition permission flags[wm]:
Enter new starting cyl[3917]:
Enter partition size[31464192b, 3092c, 7008e, 15363.38mb, 15.00gb]: 22.00gb

then i name this partition table as test1 and save

partition> name
Enter table name (remember quotes): test1

partition> q

        quit
format> save
Saving new partition definition
Enter file name["./format.dat"]:

But then a reboot (or not reboot server) partiotion3 have old value?

How I can increase partition value for new fs?

2

Use the growfs command.

3

I want to increase partition, but not filesystem!
I have only root filesystem (/). I want create new fs with space more then 20 gb! I have only 15(partition 3). About you say :"Use the growfs command."?

4

I overlook you didn't write the new label. Use the "label" command instead of "name".

5

I didn't understand, why label? how it would see it?

6

To label means to write the partition (a.k.a. slice) table. This is what you are failing to do.
