Overview - Managing Your Cell Name
Although cell names tend to be stable, there are times when you want to create and display alternative names for cells. Cell aliases can be managed by the cellalias task object. You can create multiple aliases for a single cell, but only one cellalias command.
When you create an alias, the cellalias task object forms a new principal (to represent the cell alias) in the registry, verifies the registry to make sure the cell's Security replicas are current, creates an alias name in CDS and updates each CDS replica. The cellalias task object also performs a hostdata operation on each host in the cell for which you are creating the alias. All dced objects, as well as the dcelocal/dce_cf.db and dcelocal/etc/security/pe_site files, are updated to reflect the new alias name. If your cell contains many hosts, this action can take a long time to complete.
