MSA2324 DC with Cisco MDS9124 - MSA cannot discover hosts

Hi,

First the problem, the MSA2324 is unable to discover any hosts when they are attached to the fabric.

We have a MSA2324 DC which is connected to two (2) Cisco MDS9124 switches. They are connected as per the normal redundant connection path (A1 >SW1 ; A2 >SW2 ; B1 >SW1 ; B2 >SW2).

The MSA host ports are configured in point-to-point mode.

The MDS is configured using just the initial VSAN1, all ports enabled, switch port default=F, default-zone=permit.

I have configured the MSA host ports as loop and attached two nodes directly and the MSA is able to discover the nodes.

I would really appreciate any help.

Thanks
Matthew

Matthew,

Try this:

Use MSA2300 CLI to detect the servers:

command# show hosts

If not visible, try to add the host (WWNs) manually.

Syntax# create host id ID nickname [profile standard|openvms|hp-ux]

Example Create an entry named Host1 for an FC host whose WWPN is 207000C0FF001122:

# create host id 207000C0FF001122 Host1


Map the volume to the host.

Check the LUN access.

Or one out of the box suggestion:

I once read about The Server Lunmap Discovery (SLD) tool in Cisco.(I have never tried it).

Cisco designed it for migration, but using this we can check if the switch itself can see the LUNs (yes LUNs) from the storage box.
