Preparing Volumes for Random Access Storage Pools

For a random access storage pool, you must define volumes.

Task	Required Privilege Class
Define volumes in any storage pool	System or unrestricted storage
Define volumes in specific storage pools	System, unrestricted storage, or restricted storage for those pools

Prepare a volume for use in a random access storage pool by performing the following steps:

1. Create and format the volume.

   Use the DSMFMT utility from the operating system command line or from the ADSM Server Utilities graphical user interface (Volume Formatter). For example, to create a volume named stgvol.001 with a size of 21MB for use in a random access storage pool, enter this command at an operating system prompt:

   > ./dsmfmt -m /usr/lpp/adsmserv/bin/stgvol.001 21
   

   If you do not specify a full path name, the command uses the current path.

   Tip:	Allocate storage pool volumes on disk drives that reside on the ADSM server machine, not on remotely mounted file systems.

2. Define the disk storage volume to ADSM.

   Use the administrative client graphical user interface or enter the DEFINE VOLUME command from the ADSM administrative client command line. This command informs the server of the name of the new volume that can be used to store client data. For example, to define the volume formatted in the previous step to the BACKUPPOOL storage pool, enter this command:

   define volume backuppool /usr/lpp/adsmserv/bin/stgvol.001
   

   Note:

   When you run the DSMFMT utility, you create a standard file. The name of this file is the name used for the storage volume when it is defined to the server.

Another option for preparing a volume is to create a raw logical volume by using SMIT.
