Chapter 18. Managing NetWare Volumes

This chapter discusses NetWare volumes. These volumes contain your users' directories and files. 

You can also delete NetWare volumes and print information about NetWare Volumes. 

About NetWare Volumes

A NetWare volume consists of up to 32 segments, which NetWare automatically numbers from 0 to 31. When a volume is created, it consists of one segment that is the size of the volume as specified by the user. To increase the size of the volume, additional segments are added to the volume. The size of the volume is increased by the size of the segment that is added. 

NetWare volumes can span multiple devices; that is, segments for a volume on an AS/400 system can be spread across multiple storage spaces. In other words, volumes cannot span drives (identified by a drive mapping letter) but volumes can span disk drives. Segments for a volume on a PC server can be spread across multiple disks. There can be up to 8 segments per storage space. The segments can belong to one or more volumes per storage space or disk. 


Working with NetWare Volumes

The Work with NetWare Volumes (WRKNTWVOL) command displays the current volumes on the network. You can use this display, shown in Figure 18-1, or you can use the following commands to create, change, delete, and display or print information about the NetWare volumes: 

  • CRTNTWVOL 
  • CHGNTWVOL 
  • DLTNTWVOL 
  • DSPNTWVOL 

* figure note not displayed.
Before you can work with Netware volumes, you must have an authenticated connection to the server. See Chapter 16 for more information.

The Work with NetWare Volumes display differs slightly for a remote server in that it does not include the Storage Space column. 

*FREE segments shown on this display are segments that have not been assigned to a volume. This *FREE space can be assigned to any other volume on any other disk device or storage space, as long as: 

  • The disk device or storage space does not already contain 8 segments that are assigned to volumes 
  • The volume you want to assign *FREE segment space to has fewer than 32 segments from this and other disk devices or storage spaces. 
You can assign a *FREE space to a volume by using the CHGNTWVOL command. You can use the full amount of the *FREE segment, or part of the *FREE space. The size of the existing volume will be increased by the size you specify. 

If the server is a local Integrated PC Server, the Storage Space column shows the names of the storage spaces, which contain the segments, associated with the device. 


Creating a NetWare Volume

The easiest way to create a volume is to use the WRKNTWVOL command and press F10. Then use option 1 on one of the *FREE segments. However, you can also specify a specific size, or you can specify the default, which is *MAXAVAIL. On the create and change volume commands, you can specify a device number or, if the server is local, you can specify a storage space name. You can also get the device number or storage space name for a local server by using the WRKNWSSTG command. If the server is remote, you must supply a device number. You can either specify a valid segment number, or allow the default *ANY to select the "best fit" segment. 

The volume is created or extended by using either the specified segment or the first free segment on the device that satisfies (or most closely matches) the requested size. 

Note also that for a remote NetWare 3.12 server, you cannot use the TEXT parameter to specify descriptive text for the volume. The text is held in an NDS object that corresponds to the volume, and NetWare 3.12 does not support NDS. 


* figure note not displayed.
Once data compression or block suballocation is set on, it cannot be turned off once the volume has been mounted for the first time.

Changing a NetWare Volume

When you change a NetWare volume, you can increase the size of the volume by specifying the new size and the segment you want the additional size to be used from. The SIZE parameter indicates the new total size for the volume. For example, if you have a volume that is currently 50MB and you want to increase it by 30MB, specify 80MB for the size. The 30MB is used from the device number (or storage space if the server is local) that you specified. 

You can change the data compression from *NO to *YES (but you cannot change it from *YES to *NO). You can also change the block suballocation from *NO to *YES (but you cannot change it from *YES to *NO). 

The volume can be mounted or dismounted by changing the volume. You can also change the text associated with the volume. 

The easiest way to increase the size of the volume is to use the WRKNTWVOL command and then press F10. Note the device number and size of free space on the *FREE entries. Then use option 2 for the volume that you want to change and specify a device number that has a *FREE segment and a new total size (not exceeding the available free space) that you want the volume to be. 

You can also change a NetWare volume from the first panel of WRKNTWVOL and also by using the CHGNTWVOL command. 


* figure note not displayed.
To decrease the size of a volume, you must first delete the volume and then recreate it with the new size. Changes to a segment or device number are only recognized if you increase the size.

Displaying NetWare Volumes

To display a volume, select option 5 from the Work with NetWare volumes display or use the Display NetWare Volume (DSPNTWVOL) command. Press Enter to display the volume segments on the volume. In Figure 18-5 notice that the NDS volume name (1) is shown with a name relative to your context in the NDS tree. If you change the context (the Change NDS Context (CHGNDSCTX) command), the NDS volume name changes to reflect the new position. For example the following command: 

CHGNDSCTX NDSCTX('.PROG.ROCH.IBM') NDSTREE(BASE_TREE)

changes the context and volume displayed to: 
 Current context . . . . . . . . . :   PROG.ROCH.IBM
  NDS volume name . . . . . . . . . :   SERVER01_SYS
