Student Exercises

Windows Server DefinitionYou should be able to make FB volumes, but first you need to define the host definition and the port. Host definitions and port definitions are required for open systems to defined the volume group which contains the FB volumes and maps to the hosts and ports we defined. Windows Under Windows OS, use software SANsurfer to find Port WWN of your Windows server FC adapters. If you have SDD installed, you can also use its command gethba to get the Port WWN of your adapters.

__ 1. Now let's define the Windows host connection. First enter the mkhostconnect command without any parameter to get the syntax.

Note The parameters you need to use are the wwname, -hosttype, and ioport parameter.

__ 2. From DSCLI, you can use the help lshosttype command to know the list of host types' parameters.





EXempty __ 3. Define your Windows Server on the DS8000 with information required. Use the mkhostconnect -wwname -hosttype -ioport command. __ a. Replace by the Port WWN of your Windows server. __ b. Replace by Win2000. __ c. Replace by the list of the DS8000 ports (i.e. I0100,I0102). __ d. Replace by SS49WinTeamX (where X is your Team number).

Note Repeat this command if your Windows Server uses a second FC adapter card.
