Problem
How to create contiguous space on disks when there are gaps between subdisks using the Volume Manager Storage Administrator graphical user interface, when there is space on the disk but you don't have a large enough block to create the subdisk you need.
Error
no block size large enough to create subdisk.
Solution
You can find these instructions in the Volume Manager
Storage Administrator (VMSA) Guide. However, they have been placed
together in this Tech Note to provide you an efficient way of moving the
subdisks on a disk without losing data.
I) Evacuate all data off the current disk to a free disk of the same size or larger:
1. Select the disk that contains the objects and data to be moved to another disk.
2. Click Disks | Evacuate (Selected menu) or Disk Evacuate (Command Launcher).
3. Complete the Evacuate Disk dialog box as follows:

3. Complete the Evacuate Disk dialog box as follows:
Disk Name: If the correct
disk name is not already displayed in this field, type the disk name or click
Browse to select the disk.
Target Disk(s): Click the
Browse button next to the Target Disk(s) field and select a
disk.
When you have provided all necessary information in the dialog box, click OK.
II) Move all subdisks belonging to it's corresponding volume one by one back to the original disk to make them contiguous:
1. Select the volume with the subdisk to be moved.
2. Click Volumes | Show Layout (Selected menu).
3. In the Volume Layout Details window, select the subdisk to be moved to another disk.
4. Click Subdisks | Move (Selected menu) or Subdisk Move (Command Launcher).
5. Complete the Move Subdisk dialog box as follows:
Source Subdisks: If the
correct subdisk name is not already displayed in this field, type the subdisk
name or click Browse to select the subdisk.
Target Disk Name: Type
the name of the disk to which the subdisk should be moved or click Browse
to select a disk.
III) Join the subdisks for each column to now be contiguous:
1. Select the volume with the subdisks to be joined.
2. Click Volumes | Show Layout (Selected menu).
3. In the Volume Layout Details window, select the subdisks to be combined into a single subdisk.
4. Click Subdisks | Join (Selected menu) or Subdisk Join (Command Launcher).
5. Complete the Join Subdisks dialog box as follows:
Source Subdisks: If the
correct subdisk names are not already displayed in this field, type the subdisk
names or click Browse to select the subdisks. Specify at least two
subdisks.
Target Subdisk Name: If
the name of the new combined subdisk is not already displayed in this field,
type a new subdisk name.
When you have provided all necessary information in the dialog box, click OK.
IV) Follow steps II - IV for each disk.
V) Once complete run a final vxdg free to make sure that all space is at the end of the disks.
