What is the relationship between master and slave Redis instances?

0

The master and slave instances are deployed in pairs. If a master instance is faulty, the remaining master instances in the cluster will select a slave instance to serve as the new master instance. The selection can be performed only when more than half of the master instances are normal. Each Redis cluster in a FusionInsight Farmer environment supports one-to-one mapping between active and slave instances.

Method used to distinguish master and slave subracks onsite
The LED indicator on the SCC or AUX board indicates whether the subrack is a master or slave subrack when subracks are cascaded. "0" indicates the master subrack. "EE" indicates that the subrack ID is incorrect or cannot be read. Other values indicate slave subracks. For example, "1" indicates slave subrack 1, and "2" indicates slave subrack 2.
