The VMALLOC command operates in one of two modes, depending on whether the “USE” configuration file statement is specified. Without it, VMALLOC generates an input file suitable for processing by the DIRECTXA command, or by a VM Directory Manager product. When “USE” is defined, VMALLOC calls CA VM:Secure or CA VM:Director to allocate the specified user ID and disk space.
The syntax of the command is given earlier, in the chapters where you use it.
Using VMALLOC with the DIRECTXA Command
You may add user ID entries and minidisk definitions to your USER DIRECT file and bring the changes online with the DIRECTXA command. See the IBM CP Planning and Administration guide for your release of VM for details on creating user directory entries. VMALLOC generates a directory entry file on the A-disk for use as input to DIRECTXA.
MDISK statements are generated as comments which specify the required disk sizes in units of blocks of a specified block size. If you configure the DEVTYPE statement, sizes are given in units of cylinders or FBA 512-byte blocks. If you configure the VOLUME statement, the specified volume will appear in the generated MDISK statements.
Using VMALLOC with a Directory Manager Product
VMALLOC generates a directory entry file on the A-disk for use as input to a directory manager product, such as DIRMAINT from IBM, CA VM:Secure, or CA VM:Director. See the relevant product manuals for details on adding user IDs and minidisk space with these products.
MDISK statements are generated as comments which specify the required disk sizes in units of blocks of a specified block size. If you configure the DEVICE statement, sizes are given in units of cylinders or FBA 512-byte blocks. If you configure the VOLUME statement, the specified volume will appear in the generated MDISK statements.
Using VMALLOC Automatic Resource Allocation with CA VM Secure or CA VM Director
If either of these CA directory manager products is installed and the "USE" parameter is configured, then VMALLOC calls the CA Directory Manager product directly to allocate the needed user ID entries and disk space.
