Description

This manual check is done in order to check FC connectivity to InfiniBox systems in HP-UX hosts.

This is a manual configuration step that is currently not supported in Host Power Tools.

Manual configuration guide

Recommended settings

To list the fc ports, type:

ioscan -fnC fc

With the output of the following form:

Class     I  H/W Path  Driver S/W State   H/W Type     Description
================================================================
fc        0  0/2/1/0   fcd   CLAIMED     INTERFACE    HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1)
                      /dev/fcd0
fc        1  0/2/1/1   fcd   CLAIMED     INTERFACE    HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 2)
                      /dev/fcd1

 

To check that an FC port is on, and to get it's WWN:

fcmsutil /dev/fcd1

With the expected output:

...
N_Port Port World Wide Name = 0x50060b00003b2226
...
Driver state = ONLINE
...

 

To check if the system is visible, type:

ioscan -m lun -C ctl

You should see a list of all the storage controllers that are visible to this host. For each port, you should see something like:

Class     I  Lun H/W Path  Driver  S/W State   H/W Type     Health   Description
======================================================================
ctl       5  64000/0xfa00/0x9   esctl  CLAIMED     DEVICE       online   NFINIDATInfiniBox
             0/2/1/1.0x5742b0f000753611.0x0
                      /dev/pt/pt5

Note that the state should be CLAIMED, and health should be online.

Manual fix

If the system's WWN's are not visible to the host, you can:

  • Check the zoning between the host and InfiniBox in the FC switch.
  • Perform a rescan:

    ioscan -fnC fc

Updating the SCSI storage controller attributes for better performance

After connecting InfiniBox, and checking for FC connectivity, one should do the following configuration change on the storage controller H/W Path:

scsimgr set_attr -H 0/2/1/1.0x5742b0f000753611 -a tport_qdepth_enable=1 -a tport_qd_dyn=0 -a tport_max_qdepth=4096
scsimgr save_attr -H 0/2/1/1.0x5742b0f000753611 -a tport_qdepth_enable=1 -a tport_qd_dyn=0 -a tport_max_qdepth=4096

Where 0/2/1/1.0x5742b0f0004e2c11 is the target path of InfiniBox, not including the lun. This target path can be retrieved using ioscan -m lun -C ctl (See the example above).
