Altering Virtual Disk Attribute Values

The ALTER DISK Command (page 14-48) changes configured attributes for a virtual

disk.

Considerations for ALTER DISK and Virtual Disks

•

The process must be in the STOPPED state or not running before you can change

its configuration.

•

Changes take effect when you restart the process.

•

All configuration changes related to SMF require that:

TMF must be running on the system.

The SMF master process ($ZSMS) must be in the STARTED state.

The CATALOGLOCATION volume of the SMF Master Process must be in the

STARTED state and enabled by TMF.

Example

1. Display detailed information about the configured attributes of the disk you want to

alter:

-> INFO $VDISK00, DETAIL

An asterisk (*) marks those attributes you can alter.

2. Stop the disk process:

-> STOP $VDISK00

3. Change one or more Virtual Disk Attributes for the ALTER COMMAND

(page 14-51). For example, this command changes the maximum size of the

audited name table:

-> ALTER $VDISK00, ANTCAPACITY 1000000

4. Verify the change is entered into the system configuration database:

-> INFO $VDISK00, DETAIL

5. Restart the disk process:

-> START $VDISK00
