How to add partition?
Hello.
I want to grow up ufs partition.
Currently i have such confoguration:

Code:
#format
AVAILABLE DISK SELECTIONS:
       0. c1t0d0 <DEFAULT cyl 7829 alt 2 hd 255 sec 63>
          /pci@0,0/pci15ad,1976@10/sd@0,0
Specify disk (enter its number): 0
selecting c1t0d0
[disk formatted]
Warning: Current Disk has mounted partitions.
/dev/dsk/c1t0d0s0 is currently mounted on /. Please see umount(1M).
/dev/dsk/c1t0d0s1 is currently used by swap. Please see swap(1M).
/dev/dsk/c1t0d0s3 is currently mounted on /u. Please see umount(1M).
/dev/dsk/c1t0d0s7 is currently mounted on /export/home. Please see umount(1M).

#fdisk
             Total disk size is 10443 cylinders
             Cylinder size is 16065 (512 byte) blocks

                                               Cylinders
      Partition   Status    Type          Start   End   Length    %
      =========   ======    ============  =====   ===   ======   ===
          1       Active    Solaris2          1  7831    7831     75
          2                 Solaris2       7832  10441    2610     25

What I have to do to add additional space from this partition 2 to /u ?

Hmm, and then your system become unbootable. Not the best suggestion.

Having more than one partition of type Solaris2 (or Solaris) is unsupported. You might be confusing slices and primary partitions. If you want to make use of your second primary partition, give it a different type, whatever actually, and then the simpler way would be to create a ZFS pool on it.

I deleted second partition, now i have unallocated space at the end of disk.
When i go format - partition - print, i see
Code:
Total disk cylinders available: 7829 + 2 (reserved cylinders)

Part      Tag    Flag     Cylinders        Size            Blocks
  0       root    wm      80 - 1454       10.53GB    (1375/0/0)  22089375
  1       swap    wu       1 -   66      517.72MB    (66/0/0)     1060290
  2     backup    wm       0 - 7828       59.97GB    (7829/0/0) 125772885
  3 unassigned    wm    1455 - 7828       48.83GB    (6374/0/0) 102398310
  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       home    wm      67 -   79      101.98MB    (13/0/0)      208845
  8       boot    wu       0 -    0        7.84MB    (1/0/0)        16065
  9 unassigned    wm       0               0         (0/0/0)            0

How i can manage slices here if cylinders more than 7832 are unreachable?

Deleting the second partition isn't the best way to use the space it contains. Once again: If you want to make use of your second primary partition, give it a different type than Solaris2 and then create a ZFS pool on it.

It is not important to use one or two primary partitions. The task is to grow /dev/dsk/c1t0d0s3.
Is it possible to do growfs on non ufs partition?

For "zpool create" i need a name of new area. I create again second partition with Unix type.
But it name does not appear in format output.
