Example 1, you need offline pools at No.3 JBOD if you want to replace No.2 JBOD in Single-Path mode. Because NAS can not access No.3 JBOD due to lack of loop cable.
Example 2, you need offline pools at No.2 JBOD and No.3 JBOD if you want to replace No.1 JBOD in Single-Path mode due to lack of loop cable from NAS to No.3 JBOD.
In this case, we will show you how to replace No.2 JBOD without stopping storage service running on other JBODs.
If an existing pool member resided on this JBOD, please take pool OFFLINE first!
Then you can start to remove the JBOD by following steps below.
