Hi, Chan Kok Leong
One possible explanation for this apparent discrepancy is the the command "Q
DASD DETAILS
0405" returns information about a real DASD volume at real address 0405. The
CPFMTXA
command returns information on the minidisk belonging to the issuing virtual
machine at
(virtual) address 0405. For example, if you are logged onto, say, your RedHat
installation
id, the CPFMTXA command will show you information on the install user id's 0405
minidisk,
which appears to be in this case 156 cylinders.
It's easy sometimes to get confused between devices' real and virtual
addresses, and which
commands take real addresses and which expect virtual ones.
Hope this helps some.

Hi all,
I have a DASD at 0405.
q dasd details 0405
0405 CUTYPE = 2107-E8, DEVTYPE = 3390-0A, VOLSER = MV0405, CYLS =

According the query it has 3339 cylinders.
But it seems that only 156 cylinders are visible to CP. For example, here
I try to CPFMTXA on it:
cpfmtxa

ENTER THE VDEV TO BE PROCESSED OR QUIT:

ENTER THE VOLUME LABEL FOR DISK 0405:

This happened after an aborted Red hat installation and this particular
DASD was supposed to hold the root filesystem.
Is the DASD corrupted? Can it be fixed? With ICKDSF?
Any hints is much appreciated.
