how to check DMP in VCS is working?

Hi,

 

We installed Storage foundation HA 6.1 with DMP set with all option marked.

Before that we had the EMC power-path application, where we could see that multipathing sees all disks from all available paths.

now we have the SFHA DMP option installed, But I can't figure out where do I see that the system see all disks through all switches.

 

Any way to check this via GUI or command line without having to manually disconnect disks to check it?

 

Thanks,

 

Sarah

You should be able to use

You should be able to use vxdmpadm command, which is availalble in UNIX and Windows, but unfortunatley Symantec have the extremely annoying habbit of making the syntax different between UNIX and Windows so I am unable to give you the exact the syntax as I don't have access to a Windows server the moment.

On UNIX you can run:

 # vxdmpadm listenclosure
ENCLR_NAME        ENCLR_TYPE     ENCLR_SNO      STATUS       ARRAY_TYPE     LUN_COUNT    FIRMWARE
===================================================================================================
disk              Disk           DISKS                CONNECTED    Disk        2         0491
hitachi_usp-v0    Hitachi_USP-V  12345                CONNECTED    A/A        39         6008

 

# vxdmpadm listctlr
CTLR_NAME       ENCLR_TYPE      STATE        ENCLR_NAME      PATH_COUNT
=========================================================================
c3              Disk            ENABLED      disk                 2
c0              Hitachi_USP-V   ENABLED      hitachi_usp-v0       39
c1              Hitachi_USP-V   ENABLED      hitachi_usp-v0       39

 

 

and get details of each disk using:

# vxdmpadm -v getsubpaths enclosure=enclosure_name

 

If you look at SFW admin guide (http://www.symantec.com/business/support/resources/sites/BUSINESS/content/live/DOCUMENTATION/7000/DO...

then you can get syntax of vxdmpadm for Windows, so try:

vxdmpadm arrayinfo

vxdmpadm pathinfo

Hi Sarah,

You can check the number of paths seen by SFW's DMP by either using the GUI or the CLI.

In the CLI you can use the vxdmpadm.exe utility to get dmp related information.  For example, "vxdmpadm deviceinfo harddisk5" will give you a list of paths and general detail about harddisk5.

In the GUI you can expand the DMP DSM section on the left, expand the DSM and array used to show the harddisks, then click on the harddisks and go to the DMP DSM tab on the right.  The number of paths seen for that device will be shown at the bottom of the right panel.
