EMC Symmetrix VMAX – Viewing Port Details

When building a Vblock720 I use the following information to assist in Zoning and Masking of UCS Blades.

In order to gather the wwn’s of all the VMAX front-end director ports the following command is quite useful. (See screenshot below)

symcfg -sid XXX list -fa all

vmax_fa_all1

I also find the following command very helpful:
symcfg -sid XXX list -fa all -port
This will give you the list of all Front-End adapters on the VMAX displaying both online and connection status details. From the screenshot below you can see that FA-5E P0 and P1 are both online and P0 is connected (in our case it is connected to an Cisco MDS 9513 Multilayer Director). You can also see that while both FA-7H ports are online neither are connected to a port on the MDS. FA-7G both ports are online and both are connected to ports on MDS.

vmax_fa_port

In order to view the online status of all the Back-end director ports:
symcfg -sid XXX list -da all
From the output of this command you can also view the number of hyper volumes per port and how they are distributed accross the backend.

vmax_da_all

If you wish to display the online status of both Front-end and Backend ports through a single command:
symcfg -sid XXX list -dir all

VMAX_DIR_ALL

View Port status and connection status of RDF Ports:
symcfg list -RA ALL -PORT

RDF_PORT

List logins shows hosts logged into the port specified:
symaccess -sid XXX -dirport 1E:0 list logins

Using Unisphere for VMAX:

Front-End director ports:
Uni_FA

Backend director ports:
Here you see the 8 Director10 ports; physically there is only 2 backend ports on the director using QSFP it branches off to 4 connections to the system disk enclosures.
UNI_DA

RDF ports:
RDF_PORT_UNI

  1. Hi Dave, I’ve got 2 VMAX10K arrays managed by Unisphere for Vmax (with Perf). In order to troubleshoot performance issues I’m required to use Unisphere interface. Is there a way to get FA-port statistics using symcli (allows scripting)?
    Thanks

  2. What are P2 and P3 ?
    i.e. Does this suggest that it is possible to get 4x port FA HBA’s from EMC to double up the number of ports on an FA ?

    • P2 and P3 are N/A in the config shown here. What you see here are 2xFA IO Module’s per director with each module having 4xFC Port’s. For example Director 5 has an IO Module with ports 5e0,5e1,5f0,5f1 and a second IO Module with 5g0,5g1,5h0,5h1. There are different options for FA Modules but a 4 port IO Module is the max (2/4/8Gbs)

  3. Is there a way to script and find out which hosts were logged into FA ports and then went offline or a script which will alert us when any hosts that are currently logged in have logged out on DMX\VMAX

  4. Hello David, I am wondering about 6 fabric swith configuration in one of our new environment .Normally there are 4switches used in pairs 2+2 one is odd and even fabric but why 6 switches used . please explain 2 are Cisco and 4 are Hp cisco blades switches
