 PowerStore 500T has a software issue that may lead to a single node reboot and sometimes both nodes may reboot leading to service disruption.

 

Target Audience

This procedure is targeted at customers, partners, and Dell employees who plan to add drives to a PowerStore 500T running code levels below PowerStoreOS LTS-v4.1.0.4.
