RE: Sharing 280D fiber tape card

[Pete Massiello - ML <pmassiello-ml@xxxxxxxxxxxx>]

Rob,

	On mail1, you should put in the exclude resources for the Optical  & Tape, so that the other NWSD will provide that.   This way one NWSD has the disks, and the other NWSD has the optical and tape.  Then if you are going to boot from DVD, put the I_BASE_01 in the DVD, do a manual IPL of the partition.  The partition should point to the SCSI which is "hosting" the optical.  Also, make sure you put a 7 or 9 on CTL05 & CTL06 so you really know which ones they are.

	Pete

Following section "Creating an IBM i logical partition that uses IBM i virtual I/O resources" starting at pdf page 125 (printed page 117) of "Power Systems Logical Partitioning" available at http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/topic/iphat/iphat.pdf

On my HMC I created the new guest lpar.
Load source:  Client SCSI Slot 2
Alternate restart device:  Client SCSI Slot 3

The Guest lpar has the following:
             adapt
Type          id   Server         Partner             Required
Client SCSI    2   gdihq(2)       5                   Yes
Client SCSI    3   gdihq(2)       6                   Yes
Server Serial  0   Any Partition  Any Partition slot  Yes
Server Serial  1   Any Partition  Any Partition slot  Yes


The Host lpar has (both dynamically and in profile config - verified)
             adapt
Type          id   Server         Partner             Required
Ethernet       2   N/A            N/A                 Yes
Ethernet       3   N/A            N/A                 Yes
Server SCSI    4   Any Partition  Any Partition Slot  Yes  (just was 
there)
Server SCSI    5   MAIL1(4)       2                   No
Server SCSI    6   MAIL1(5)       3                   No
Server Serial  0   Any Partition  Any Partition slot  Yes
Server Serial  1   Any Partition  Any Partition slot  Yes

On gdihq I enter WRKHDWRSC *CMN and I see (subsetted)
Resource        Type  Status                Text

ADDNWSSTGL NWSSTG(MAIL1001) NWSD(MAIL1)
Repeat for the six storage devices.
Verified that the settings for this lpar are D mode IPL.
Tried to start it using Activate Profile and it died with B2004158.
Shut it down immediately.  Varied on NWSD's MAIL1 and MAIL1TO.  Tried again.  Same error.  Hmm, I wonder if loading a disc into the optical drive will make a difference?  :-) Do I need to vary off tape/opt on GDIHQ first?

Rob,

     On your NWSD to the guest LPAR do NOT restrict the tape drive ( 
RSTDDRVRSC Parm  ) either by name, *ALLTAPE or *ALL.

     Now vary OFF the tape drive on the host LPAR.

     The drive should appear and be available to the GUEST lpar, simply 
vary it on.

     Should be as simple as that.

     Twist: IBM recommend that you have your guest's disk on a separate 
v-SCSI channel from Tape and Optical which means that you need TWO NWSDs 
configured and to do that you need TWO vSCSI pairs between the guest and 
the host.  I configure the first NWSD to have the disk on it and 
configure RSTDDRVRSC(*ALL) on that one. For he second NWSD I append the 
letters "TO" (for Tape and Optical) to the name to keep it straight in 
my head  [ SO NWSD one might be GUEST1 and the other GUEST1TO ]   Now 
you can Vary off the ..TO NWSD should you need to make changes and you 
won't upset the guest LPAR.

     Also personally I do not use Power Controlling on these type of 
LPARs.

         Hope that helps!
