Well, having done this just this week, this is what I do.
Using a putty client you may have downloaded from
http://www.chiark.greenend.org.uk/~sgtatham/putty/
Start a session to vios11.corp.dekko.com (or the appropriate vios lpar for
the rack in question). Don't forget the .corp.dekko.com.
Sign on as ... with a password of ...
Remembering these partition numbers (which you can verify via the HMC):
1-vios11
2-vios12
3-RACK1HST
4-GDWEB
5-GDIHQ
6-GDISYS
7-MAIL1
8-TSMAIX
Enter in this command: lsdev
This will show you a large list of stuff including cd0, cdrom, vhost0,
vhost1, vhost2, etc. Interesting information to know but you could have
skipped the lsdev command.
Enter in the command: lsmap –all | more
That’s lsmap space –all space pipesymbol(above enter key on laptops) more
Three columns:
SVSA, this will be where you find the vhost# value,
Physloc, this will be where you find the virtual scsi adapter (like C114)
Client partition ID, 0x00000003 is partition 3.
The following tells us that Partition 4 currently has the dvd drive
virtualized to it:
SVSA Physloc Client
Partition ID
--------------- -------------------------------------------- ----------
vhost1 U8286.41A.214403V-V1-C114 0x00000004
VTD cdrom
Status Available
LUN 0x8100000000000000
Backing device cd0
Physloc U78C9.001.WZS00UA-P2-D27
Mirrored N/A
Record the vhost from the SVSA column which matches the partition number
we want to assign it to from the Client Partition ID column:
__________________
Not the partition which has it currently assigned to. Note how the number
on the end of vhost does not match the number of the client partition id?
Now we will remove the DVD from any partition which may have it
virtualized to it with:
rmvdev –f –vdev cd0
And we will assign it to our desired partition with this next command.
This this following command replace vhost0 with the vhost from the SVSA
column which matches the partition from the client partition id. You
recorded this just a step or two ago.
mkvdev –f –vdev cd0 –vadapter vhost0 –dev cdrom
Verify you got this right by rerunning: lsmap –all | more
Now on the lpar of IBM i you now want to use it on, look for it with
WRKCFGSTS *DEV *OPT
Don't be surprised to find more than one active. It's gotten strange.
I've been known to vary these off and delete them BEFORE I run the above
steps in vios.
When you stick in a DVD, and the light on the drive stops flashing DSPMSG
QSYSOPR should show you
OPT1410-Volume C2989365_06 added to optical device.
If you press help on that you will see
Cause . . . . . : Volume C2989365_06 was added into optical device
OPT01.
The name of the optical drive, in this case OPT01, will be at the end.
