This accessible-for-notify SnmpAdminString carries the machine type of the IBM SAN Volume Controller (SVC) node reporting a trap, included as a varbind in the tsveETrap/tsveWTrap/tsveITrap notifications. An admin reads this field in a received trap to identify which model of SVC hardware raised the alert without having to separately query the device. For example, this field might contain a value like '2145' identifying the SVC machine type in an incoming error trap.
