DS8886 should allow query of FICON/FCP connectivity

We have a large number of IBM DS8886's in our environment and frequently have connectivity issues for our FICON and FCP ports. Unfortunately, we do not have any visibility within the DS8886 to the connection (if any) at the other end of the cable. This frequently then requires that someone physically trace the cabling to the other end if configuration sheets do not match the actual cabling. We would like a DSCLI command and GUI commands that would show the connection state of any connected FCP or FICON port. This should include information like s/n and port at the destination end.

    Need to discuss with the GUI team. This has some overlap with RFE #73210 (DS8K GUI identification of used ports on IO cards).

    Recently released (R8.3) enhancements to DS8800 Read Diagnostic Parameters (RDP) function may provide the information you need. At least, it provides the WWPN of the attached port and the current state of the link, including the active link speed and link speed capabilities.

    Please see this link in the knowledgecenter and look for the -rdp option on showioport:
    https://www.ibm.com/support/knowledgecenter/ST5GLJ_8.3.3/com.ibm.storage.ssic.help.doc/f2c_clishowioport_1kyvlb.html

    For example:
    dscli>showioport -rdp I0103
    ID I0103
    WWPN 50:05:07:63:03:03:00:45
    Attached WWPN 50:05:07:63:03:FF:C0:45
    …
    Port Speed Capabilities 4GFC 8GFC 16GFC
    Port Operating Speed 16GFC
    …

    The lsioport command can be used to create your list of ports IDs of interest.

    This information is not yet available using the GUI.
