Hi,
I have a strange problem with some DASD.
The disks at 400-420 are used by MVS, and are
primaries in PPRC pairs (actually, HDS's HRC,
they are on a 9970 box).
MVS is running on a second system from VM,
but VM also has channel paths to that 9970,
and the IOCPs are identical, so both systems see
the same hardware setup.
Now, here is a sequence of operations that makes no
sense to me.
Q 400
DASD 0400 OFFLINE
READY; T=0.01/0.01 10:05:08
Q DUPLEX 400
HCPDMC1110E DEVICE 0400 IS NOT IN A DUPLEX PAIR.
READY(01110); T=0.01/0.01 10:05:13
VARY ON 400
0400 VARIED ONLINE
1 DEVICE(S) SPECIFIED; 1 DEVICE(S) SUCCESSFULLY VARIED ONLINE
READY; T=0.01/0.01 10:05:40
Q DUPLEX 400
HCPDMC332E INVALID CONTROL UNIT TYPE - 0400
READY(00332); T=0.01/0.01 10:05:49
#### I guess this makes sense, the CU is defined as 2105.
Q 400
DASD 0400
READY; T=0.01/0.01 10:05:52
#### Why doesn't VM see the VOLSER??
ATT 400 SYSTEM
HCPATM1117I DASD 0400 WAS NOT ATTACHED TO THE SYSTEM
BECAUSE IT IS THE SECONDARY IN A PPRC PAIR.
READY(01117); T=0.01/0.01 10:07:48
#### HUHHHH???????
ATT 400 *
DASD 0400 ATTACHED TO XMSL 0400 WITH DEVCTL
READY; T=0.01/0.01 10:09:29
TYPE Q400 DSF C
PPRCOPY QUERY UNIT(400)

ICKDSF Q400 DSF C Q400 DSFLOG A
READY; T=0.01/0.02 10:09:54
#### The real volume is attached, so ICKDSF can see
the true PPRC status of the volume.

#### ICKDSF clearly shows that this disk is a PRIMARY volume:
0400 PRIMARY DUPLEX ACTIVE 9975 00 9905 00
So, where is VM dreaming up that it is a SECONDARY?
Why can't I attach the volume to system??
Thanks!
