This read-create SnmpAdminString (1-64 characters) is the name of a zone alias, which must be unique within its VSAN and can be changed by writing a new value or via zoneAliasClone; it must be set before or concurrently with activating the row via zoneAliasRowStatus. Admins use aliases to group members under a friendly name that can be referenced in multiple zones. For example, an admin who frequently references the same set of storage ports across several zones would define this alias name once and reuse it, rather than repeating the raw member list.
