Thanks I need to know if my server has dual HBA and if multipath has been configured. For Multipath I ran lspath and it shows all drives and if MPIO is configured for that drive.

Thanks for any input.

You can type this command

lsdev -Cc adapter

And you will see a list of devices

Then you can type lscfg -vl fcsX for every hba that has in the list.

To see the kind of multipath on your disks type lsdev -Cc disk

I hope this helps you

Greetings

You could look at the description of the "lsdev" output as well. Mine say "Dual Port"

```nohighlight
hostname:/:# lsdev -Cc adapter | grep fcs
fcs0 Available 01-00 8Gb PCI Express Dual Port FC Adapter (df1000d222122b15)
fcs1 Available 01-01 8Gb PCI Express Dual Port FC Adapter (df1000d222122b16)
hostname:/:#

```

You can also see that only the last "T#" is different in the "Hardware Location Code" as shown by the "lscfg" command indicating that they are both located in the same physical location which also points to a dual port adapter.:

```nohighlight
hostname:/:# lscfg -vl fcs0 | grep "Hardware Location Code"
        Hardware Location Code......U55AA.001.XXXX2X5-P1-C4-T1
hostname:/:# lscfg -vl fcs1 | grep "Hardware Location Code"
        Hardware Location Code......U55AA.001.XXXX2X5-P1-C4-T2
hostname:/:#

```
