Renaming or deleting a compatibility mode aggregate

To rename a compatibility mode aggregate, use the IDCAMS ALTER command with the NEWNAME parameter. You cannot rename an aggregate if it is mounted.

After the rename is done, the name of the file system stored in the zFS aggregate will not match the aggregate name. This is a requirement for compatibility mode zFS aggregates. To reconcile the file system and aggregate name, the zFS file system must be mounted initially as read/write after the IDCAMS RENAME is complete. This allows zFS to reconcile the file system name with the new aggregate name. After the name is reconciled, the aggregate can then be mounted read-only.

The example in Figure 1 assumes that:
  • The data component name is the same as the cluster name with DATA appended
  • You want to rename both the cluster name and the data component name.
Figure 1. Example job to reconcile the file system and aggregate name
//SUIMGVMS JOB (ACCTNO),'SYSPROG',CLASS=A,             
//             MSGCLASS=X,MSGLEVEL=(1,1),NOTIFY=&SYSUID
//STEP01   EXEC PGM=IDCAMS                             
//SYSPRINT DD  SYSOUT=*                                
//SYSIN    DD  *                                       
          ALTER PLEX.JMS.AGGR006.LDS0006 -             
             NEWNAME(PLEX.JMS.AGGR008.LDS0008)         
          ALTER PLEX.JMS.AGGR006.LDS0006.* -           
             NEWNAME(PLEX.JMS.AGGR008.LDS0008.*)

To delete a compatibility mode aggregate, use the IDCAMS utility DELETE command. You cannot delete an aggregate if it is mounted. Figure 2 shows a sample job that deletes both the cluster name and the data component.
Figure 2. Example job to delete a compatibility mode aggregate
//SUIMGVMD JOB (ACCTNO),'SYSPROG',CLASS=A,             
//             MSGCLASS=H,MSGLEVEL=(1,1),NOTIFY=&SYSUID
//STEP01   EXEC PGM=IDCAMS                             
//SYSPRINT DD  SYSOUT=*                                
//SYSIN    DD  *                                       
          DELETE PLEX.JMS.AGGR006.LDS0006
