    Hello everyone,

    Quick question about Shark storage. I'm connecting an AIX5.1 ML3 box to a
    shark. Everything seems normal except when I do an lsdev -Cc disk, I see
    Two Vpaths (which I expect) but I see four hdisks for fcs0 and only two
    hdisks for fcs1.

    This isn't normal is it?

    lsdev -Cc disk
    hdisk0 Available 40-60-00-4,0 16 Bit LVD SCSI Disk Drive
    hdisk1 Available 40-60-00-8,0 16 Bit LVD SCSI Disk Drive
    vpath0 Available Data Path Optimizer Pseudo Device Driver
    vpath1 Available Data Path Optimizer Pseudo Device Driver
    hdisk2 Available 11-08-01 IBM FC 2105800
    hdisk3 Available 11-08-01 IBM FC 2105800
    hdisk4 Available 11-08-01 IBM FC 2105800
    hdisk5 Available 11-08-01 IBM FC 2105800
    hdisk6 Available 14-08-01 IBM FC 2105800
    hdisk7 Available 14-08-01 IBM FC 2105800

    lsdev -Cc adapter | grep fcs
    fcs0 Available 11-08 FC Adapter
    fcs1 Available 14-08 FC Adapter

    Filesets that I am running:
      devices.sdd.51.rte 1.5.0.0
      devices.common.IBM.fc.rte 5.1.0.51
      devices.fcp.disk.array.rte 5.1.0.61
      devices.fcp.disk.rte 5.1.0.58
      devices.fcp.tape.rte 5.1.0.52

    I don't know if it makes a difference but there are two luns mapped that
    are 840 Gb each. Each fibre-channel adapter is configured to use four ports
    on the shark.

    Thank you all in advance.

    Drew
