No Path Available for 18500 V3 Hosts

Publication Date:  2019-04-10 Views:  28 Downloads:  0
Issue Description

Two 18500 V3 storage systems are deployed in active-active mode and status of devices in the two active-active ends displayed on DeviceManager is normal. However, when the customer runs the upadmin show path command on the host to view the paths between the host and the active-active arrays, Path state is Fault.


Handling Process

1. Log in to the DeviceManager and view all events. An event indicating that links between the host and arrays are faulty is recorded.

2. Check the physical links between the host and active-active arrays. The links are faulty.

3. Check all physical links. It is found that the link between the host and switch is faulty. Replace the HBA card.

4. Log in to the host CLI and run related commands to check the paths between the host and the active-active arrays. The Path state is Normal.

Root Cause

The host HBA card is faulty.

Solution

Replace the faulty HBA card to restore the physical links.

Suggestions

If host paths are abnormal, you are advised to check status of physical links between the storage and host first.
