Hi: You asked for a minidisk at virtual address 100 starting at cylinder 51 for
3,338 cylinders, taking us to cylinder 3,388. There are only 3,338 cylinders on
a 3390-03 DASD.
If you CHANGED the mdisk statement to mdisk 3390 0051 156 MV0405 MR READ
WRITE MULTIPLE
You assigned a mdisk of 156 cylinders starting at cylinder 51, so u just space
allocated cylinder 51 to 206 on the 3390-03 volume.

Subject: Re: Missing DASD cylinders. DASD corrupted?
Hi,
Thanks Dave (Jonathan and Bernie too) for the hints. Yes, you're all
correct, I do have a virtual/real address issue.
But something about this still escapes me:
As the MAINT user, I have a virtual dasd at 0405:
q v 405
DASD 0405 3390 540W01 R/W 156 CYL ON DASD 0403 SUBCHANNEL = 003
I also have a real dasd at 0405 and the volume serial is MV0405:
q dasd details 0405
0405 CUTYPE = 2107-E8, DEVTYPE = 3390-0A, VOLSER = MV0405, CYLS = 3339
CACHE DETAILS: CACHE NVS CFW DFW PINNED CONCOPY
-SUBSYSTEM Y Y Y - N N
-DEVICE Y - - Y N N
DEVICE DETAILS: CCA = 65, DDC = --
DUPLEX DETAILS: --
CU DETAILS: SSID = 0085, CUNUM = 0001
Now in the USER DIRECT entry for user LINUX1, there's a MDISK for virtual
DASD 100:
USER LINUX1 LINUX1 1024M 1024M g
INCLUDE LINDFLT
MDISK 191 3390 0001 050 MV0405 MR READ WRITE MULTIPLE
MDISK 100 3390 0051 3338 MV0405 MR READ WRITE MULTIPLE
MDISK 101 3390 0001 3338 MV0406 MR READ WRITE MULTIPLE
When I logon as LINUX1, I see this:
LOGON LINUX1
00: HCPLNM1151E LINUX1 0100 has not been linked because it is not within
CP volme extents.
And guest LINUX1 won't have a virtual DASD at 100.
After some testing, virtual DASD 0100 will link when I set the cylinder
range to be 51 to 156 instead.
It seems that LINUX1 doesn't get the real DASD 0405 but the virtual DASD
0405 instead.
Am I missing something?
