The Request to Discover an S2600 on the ISM Times Out

Publication Date:  2012-07-22 Views:  106 Downloads:  0

Issue Description

S2600 storage device
IP address of controller A:
IP address of controller B: 192,168,128,110
The S2600 fails to be discovered on the ISM by subnet. A timeout error occurs.

Alarm Information


Handling Process

1. The IP address of controller B can be discovered on the ISM.
2. Connect the network cable to controller A and select to discover devices on the same subnet. The S2600 can be normally discovered

Root Cause

1. The network cable is connected to controller B. The alarm indicates that the access to IP address of controller A times out.
2. Controller A is the primary controller. Controller B is the secondary controller.
3. Discovering storage devices by subnet is to automatically discover the IP addresses of primary controllers


To discover storage devices by subnet on the ISM, it is recommended to connect network cables to both controller A and controller B. After that, the IP address of the primary controller is successfully discovered.
If a network cable is only connected to one controller, it is recommended to discover the storage device by its IP address.
