The SYMACL unique ID for a host system can be obtained in two ways: derived from a host-based passphrase or randomly generated by the Solutions Enabler lockbox file. The host-based passphrase is a string that the user can specify to generate a unique ID for the host. The passphrase can be entered interactively using the symacl -unique -passphrase command, or stored in a file and passed as an argument using the symacl -unique -passphrase -file command. The Solutions Enabler lockbox file is a secure file that stores encryption keys and other sensitive information. The lockbox file can also generate a random unique ID for the host using the symacl -unique command. The lockbox file must be created and initialized before using this method.

 If an administrator has added custom SSL certificates and each time a client connection is made, default certificates are used, then ‘restart storsrvd’ must be completed. This is because changes to SSL certificates often require a restart of the service that uses them in order for the new certificates to be correctly loaded and used for future client connections1.

An application owner is experiencing performance issues for their application. Unisphere for PowerMax is showing the storage group is compliant with the current Service Level. A Service Level is a predefined set of performance attributes that can be applied to a storage group to ensure consistent and predictable performance. A Service Level specifies a target response time, an upper response time limit, and a lower response time limit for the storage group. If the application owner wants to improve theperformance of their application, they can adjust the Service Level to a higher level of service, which will provide lower response times and higher priority for the storage group. Unisphere for PowerMax provides five predefined Service Levels: Diamond, Platinum, Gold, Silver, and Bronze, as well as an Optimized option that automatically adjusts the Service Level based on workload characteristics. The application owner can choose a higher Service Level from these options or create a custom Service Level with their own performance parameters.

The NDM Updates feature should be used to complete the migration and address the client’s concern. The NDM Updates feature is designed to help automate the process of moving applications across arrays requiring a short application downtime. It allows application migration from a VMAX (5876) array to a VMAX3 (5977), VMAX All Flash (5978), or PowerMax (5978) array1. It supports pre-sync data between arrays and then schedule downtime to do the cutover1. References: Dell EMC PowerMax and VMAX: Non-Disruptive Migration Best Practices and Operational Guide

R11 devices are included in a Cascaded SRDF environment. In a cascaded SRDF configuration, the R1 device at the primary site is paired with an R11 device at the secondary site, which is then paired with an R2 device at the tertiary site2. References: NDM overview | Dell EMC PowerMax and VMAX: Non-Disruptive Migration Best Practices and Operational Guide | Dell Technologies Info Hub
