This accessible-for-notify SnmpAdminString carries the cluster alias of the SVC cluster that generated the trap, distinct from the cluster's formal name in tsveCLUS. An admin uses this alias, added in SVC 7.7.0, to recognize the cluster under whatever friendlier or site-specific name it's been given in the management environment. For example, an admin might see 'DR-Site-B' as the alias for a cluster whose formal tsveCLUS name is a less memorable internal ID.
