[solved].Hitachi VSP with Cisco MDS 9148.. Host Showing as “Logged out”.

Recently, we bought in Hitachi VSP as a scale up for our storage space and for DR purposes. Our fabric already has a IBM SVC with DS5020 storage. The fabric involves Cisco MDS 9148 switches.

The issue.

After proper zoning in the switches the hosts are visible in the VSP Storage manager. Also, the hostgroup creation, logical device creation followed by LUN mapping can be done. However, the LUNs are not visible in the server.

Findings

The login status of the host shows as “Logged out” in the VSP storage manager. Not sure, why after the LUN mapping process the host logs out.

Solution

Keeping the hosts mapped under VSP, we just removed the zone created for the host from the Zoneset under the Fabric switch and activated the zoneset.

Now again, the zone was added back to Zoneset and activated. Voila!’ the VSP now shows the host as “Logged in”. Not sure about why this happens. Hope this post helps someone.
