DEL AMP

Purpose  

The DEL AMP command specifies that an AMP or a range of AMPs is to be deleted from the new configuration map.

Syntax  

 

Syntax element …

Specifies …

mmmlist

one or more vproc numbers to be removed from the configuration.

AMP vprocs are numbered consecutively starting from 0 to a maximum number of 16199.

Usage Notes  

If you delete an AMP, the AMP must have a vproc number equal to the highest number for any AMP currently entered in the new configuration map.

That is, given a system with a new configuration map that describes n AMPs (whose vproc numbers are 0 through n‑1), the only AMP that you can remove from that configuration map is the AMP with vproc number n‑1.

Configuration verifies that the vproc number to be deleted exists in the new configuration map.

After the DEL AMP command is accepted, the specified AMP is deleted from the vproc list in the new configuration map, and the system displays:

The AMP is deleted.

If you type the DEL AMP command before the BEGIN CONFIG command, the command is ignored, and the system displays:

BEGIN CONFIG is not entered, and DEL AMP is ignored.

Example  

To delete an AMP that is vproc seven of the new configuration, type:

da 7

Example  

To delete AMPs that are vproc four to vproc six of the new configuration, type:

da 4 - 6
