When managing services on the ISM installed on the maintenance terminal, the Error dialog box appears and prompts Communication with device failed, or the prompt "Communication with device failed" appears when performing Discover Device.
Take measures as suggested below to avoid this problem:
Reduce the number of maintenance terminals that are simultaneously connected to the storage device through the ISM.
Log in to the storage device through serial ports or the SSH to manage the device and services in CLI mode.
A maximum of eight ISM clients are allowed to connect and operate the S2600 and the S5000 series simultaneously.
