On this I was kind of old school. I thought that tape libraries could
still not be alternate IPL devices, only alternate installation devices.
Apparently that's changed. You should no longer have to IPL from DVD and
then IPL from tape. You can now tag your tape library as the alternate
IPL device (and not just the alternate installation device).
However.
IBM had me press F13 to ignore the bus.
My old 3573 LTO4 drives appeared but not the new vtl drives.
Here's the story:
IBM assigns two WWPN's. Well actually four. Two work. Two don't. The
two which work are used in the current IBM i profile. This is the profile
you see when you go into your currently active profile for the lpar and
select properties, virtual, virtual fiber adapter. The two which won't
work are stored in the last profile you used to IPL the lpar from. So, if
you power off your lpar and power it on from a stored profile and not
'current' you've been had.
Best practice: Store your current profile as soon as you get this working
over the profile you'll use the next time you IPL from a profile.
BTW, you cannot edit these WWPN's on the HMC GUI. They are not input
capable. There is a way, as outlined at:
http://www-01.ibm.com/support/docview.wss?uid=nas8N1011009
You must remember to enter ALL virtual fiber adapters and not just the one
you want to change as it will drop the other one! Like if we just wanted
to change the virtual fiber adapter for our vtl we would still have to
change the virtual fiber adapter for our existing LTO4 library. As in
this line:
chsyscfg -m RACK3 -r prof -i
"name=gdi_default,lpar_name=GDI,\"virtual_fc_adapters=\"\"225/client/2/vios32/225/c0507607bcfa0020,c0507607bcfa0021/1\"\",\"\"205/client/2/vios32/205/c0507607bcfa000c,c0507607bcfa000d/1\"\"\""
Hey, we got that right on only the second try! We only had to change
lpar_name=gdi to lpar_name=GDI. I think we did darned good! Of course I
was using IBM Assist On Site with Mo from internals and someone from
save/restore.
225 is the virtual adapter for our vtl and 205 is the virtual adapter for
our LTO4 library.
Please vote on my RFE to make these fields input capable on the HMC
