I am having an issue seeing virtual optical drives created on my host lpar of IBM i on my guest lpars of IBM i.
I am told they should just automatically appear.
One of the things IBM had me check was that QAUTOCFG was enabled on the guest.
They also had me delete any existing virtual optical drives on the guest pointing to the host as potential conflicts.
IBM also had me go to the host and run
WRKNWSD guestname*
Only one should have
Allowed device resources . . . . ALWDEVRSC *UNRSTD
Restricted device resources . . RSTDDEVRSC *NONE
The others should have:
Allowed device resources . . . . *UNRSTD
Restricted device resources . . *ALLOPT
To change these you should
- power off the guest.
- vary off the appropriate NWSD's
- make the changes.
- vary on the NWSDs
- Start the guest
IBM also said that if you ever want to do an OS upgrade from these optical drives, and therefore need to boot from it, then you should do the following
- change your guest's partition profile on the HMC to change the Tagged I/O's Alternate Restart Device to where the optical drives are served up. On this lpar it happens to be the same as the load source drive.
- activate the guest from profile
- disable any other alternate installation devices you may have created (like the tape drive you originally restored this lpar from) using the steps "Disabling an alternate installation device" found at
https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_73/rzarm/sc415304.pdf
I followed these steps. I also deleted and recreated the virtual optical drives on the host to serve up these image catalogs. However I do not see any new optical drives on the guest. Help.
Also:
Should I change all NWSDs to
Restricted device resources . . *ALLOPT
And create a new NWSD just for optical only? This is one way to differentiate between load source and optical. This would also entail changing the guest lpar profile to tag this new nwsd as the alternate restart device.
