How to safely shutdown to Compellent SC4020?

The shutdown procedure for the SAN is on page 300 of the Dell Storage Manager 2016 R3 Administrator’s Guide: Shutting Down and Restarting a Storage Center
https://topics-cdn.dell.com/pdf/storage-sc2000_administrator-guide_en-us.pdf

I have a question, and how to turn off the account 4020 using a script? I have two uninterruptible power supplies and two servers connected to the storage, as well as an virtual machine APC PCNS there is an opportunity to use a script. the documentation says that there is only one team to turn off the - "shut down". And the most important question, is it possible to trigger this command to shutdown with a certain time delay for execution? I mean, the team should be sent with a virtual machine and uninterruptible power supply, and it should be executed on the storage after all my hosts and virtual machines are turned off. all procedures for shutting down hosts and virtual machines need somewhere 5-7 minutes.

Does anyone have any experience?

Hello dead kirill,
I had posted 2 previous answers to a similar question with specific options for the model SCv3000/3020 SAN. These posts would also work for your system.
