Attributes Within Volume Groups

Each volume’s attributes within a numerical volume group must be uniform. For example, if the first volume in a numerical volume group has been formatted with compression ON and a block size of 64 KB, all the volumes in that volume group will have these identical attributes.

If you reassign media from one volume group to another volume group (with the volgroup -foption), AMASS makes sure the media attributes from the first volume group match the attributes of the second volume group. If the values do not match, AMASS issues an error and does not complete the reassignment. For information on numerical volume groups, see “Volume Groups Defined” on page 1-13.

Change Volume Group Number

Step 1. Log in as either amass or root.

Step 2. To assign volume number 23 to volume group 100, enter the command as shown in the following example.
