Changing a User ID’s File Space Allocations

Because user IDs’ space requirements change over time, you can change the amount of SFS file space allocated to them. You can either increase a user ID’s space when that user needs more, or decrease a user ID’s space when that user needs less and you want to conserve space for others.

You can change the space allocated to a user ID by either absolute or relative amounts, but always in 4K blocks. For example, you can change a user ID’s space allocation from 1,000 blocks to 500 blocks (absolute) or add 100 blocks to the current allocation (relative).

All changes in file space allocations are within the same file pool and user storage group; you cannot move a user ID’s file space allocation from one file pool to another or from one user storage group to another, even in the same file pool.

If you reduce a user ID’s allocation, the amount of space you free up is returned to your total amount of allocatable space in this user storage group. You can then allocate that space to any other user IDs you manage.

To modify a user’s allocated file space

From CMS, enter the MANAGE command with the name of the user ID and the numeral 10. For example, to change user ID BLOEV02's allocated file space, enter the following:
```
vmdirect MANAGE bloev02 10
```
The Work with Shared File System Menu appears.

The name of the user ID you entered in the command appears at the top of the screen, for display only. The name of this user ID’s directory manager also appears at the top of the screen. This is usually your own user ID, unless you are performing SFS administration tasks for a user ID that you do not typically manage.

Select option 2, Change User’s File Space Allocation.

The Change File Space Allocation screen appears.

The screen displays the name of your default file pool, the amount of space currently allocated to this user ID in that file pool, and the amount of that space currently being used.

If you want to change the user ID’s space allocation in another file pool, type that file pool’s name over the default one.
Because user IDs can have space allocated to them in only one user storage group in a given file pool at one time, you change space allocations by file pool and not by user storage group. The result is the same as it would be if you could specify the user storage group.
To change the space allocation in the user storage group for the file pool displayed:
1. By a number of blocks: Enter that amount in the Change (+|-) field, including a plus sign to increase the allocation by that amount or a minus sign to decrease the allocation by that amount.
  For example, to increase the user ID’s allocation by 500 blocks, enter:
```
+500
```
  To decrease a user ID’s allocation by 750 blocks, enter:
```
-750
```
2. To a number of blocks: Enter that amount in the OR New Allocation field.
  For example, to change the user ID’s allocation to 5,000 blocks, enter:
```
5000
```
  If you reduce the allocation, CA VM:Director checks that the user ID still has enough space for its current data. For instance, if you try to reduce an allocation of 500 blocks to 200 blocks when that user ID is currently using 250 blocks, your request will fail. However, you are still able to change the allocation to some other sufficient size.

The CA VM:Director MODIFY command lets you change a user ID’s SFS allocation in line mode, either interactively or programmatically.

Note: For more information about using the MODIFY command, see the Reference Guide.
