  • 1.  MSA 2050 Direct attached iSCSI

    Posted Sep 05, 2018 03:06 PM

    Hello All,

    We are trying to bring up configuration if Del server with vSphere 6.5 and MSA 2050
    I am trying to verify connection by just ping host port IP on MSA

    On both vSphere and MSA it shows both ports are up and connected.

    For configuration I did

    On vSphere with Add Network Wizard >> VMkernel >> Create a standard switch and selected the NIC that connect direct to the MSA
    Identified IP in same subnet as MSA port A1.
    Trying to test connection by ping of that IP without any success.

    MSA connected with Dell server with  HPE X240 10G SFP+ SFP+ 1.2m DAC Cable.
    MSA equipped with HPE MSA 10Gb SR iSCSI SFP 4pk XCVR
    Dell server NIC is DELL X520DA2: Intel 10 GB , Dual Port Karte, SFP+

    Anything that I forgot?

    For starters, ping by default will use the management network. If your storage network is different, use vmkping to ping the MSA IP via the storage vmkernel port.

    vmkping -I vmkX MSA-IP - where vmkX is the storage vmkernel port

    Cheers,

    Supreet

    But if I run

    tcpdump-nw -I vmk1 msa-ip

    during ping I see arp packets asking where msa-ip is.

    vmk0 that is managment interface.

    vmk1 assigned to separate vswitch with physical device coonected to MSA .

    So it does look it already use right interface for ping.

    It would be very helpful to see screenshots of your host's networking configuration and vmkernel ports.

    IP connectivity issue is solved guys :smileyhappy:

    It appears local man did not connected cables as described :smileyhappy:

    Swapped A and B

    After I've asked to keep only one cable all become clear.
