– To a duplex pair that is failed duplex
– To a duplex (not failed duplex or duplex
pending) with diagnostic or device
support access authorization.
X'19' An attempt was made to enter a ‘fail duplex
pair’ PSF order to a volume that is failed
duplex.
X'1A' An attempt was made to read the output of
a sync cylinder map from a device that is
not a member of a duplex pair.
X'1B' An attempt was made to enter a ‘terminate
duplex pair,’ ‘fail duplex pair,’ or ‘direct I/O to
one device of the duplex pair’ PSF order to
a volume that is simplex.
X'1C' An attempt was made to fail a duplex pair
with the primary as the ‘failed’ device while
the duplex pair is duplex pending.
X'23' An attempt was made to terminate a duplex
pair, and the duplex pair is DASD Fast Write
pending.
X'24' An attempt was made to direct I/O to one
device of the duplex pair that is duplex
pending.
X'27' An attempt was made to write a home
address or record zero on an active duplex
volume.
X'31' An attempt was made to direct I/O to one
device of the duplex pair where the state of
the duplex pair has been verified, and the
state is not as expected.
X'3D' A Media Maintenance Reserve was received
on the primary address of a duplex pair and
was not preceded by a direct I/O to one
device of the duplex pair, or a 3380 Track
Compatibility Mode Control was received on
a device that is the primary address of a
duplex pair.
X'40' A Media Maintenance Reserve was received
on the primary address of a duplex pair that
was not failed duplex.
System Action: The command is rejected.
Operator Response: Contact a system operator or
the appropriate hardware service personnel.
v an unexpected condition occurred while
terminating a CONCOPY session, code = code.
Explanation: An attempt to end a Concurrent Copy
(CONCOPY) session has failed. The code is the
hexadecimal format code in sense byte 8 that
describes the error condition:
Code Reason
X'48' The device is not part of the CONCOPY
session being terminated.
System Action: The command is rejected.
Operator Response: None.
v an unexpected condition occurred while
executing a FLASHCOPY command, code = code.
Explanation: An attempt to execute a FLASHCOPY
command has failed. The code is the hexadecimal
format code in sense byte 8 that describes the error
condition:
Code Reason
X'37' A command was received while the
subsystem was attempting to install a new
microcode load.
X'56' The source or the target volume has pinned
data.
X'61' Discard not allowed to a volume with the
specified extents overlapping a FlashCopy
or Concurrent Copy operation.
X'82' One of the following conditions must be
corrected:
– The resources required to complete this
command are not available in the control
unit.
– The number of Flash Copy relationships
exceeds the maximum allowed.
– The target device is not available.
X'83' The battery feature must be installed and
operational for this command to be used.
X'84' One of the following conditions must be
corrected:
– The volumes specified are not the same
track type.
– The target volume has fewer tracks than
the source volume.
– The source and target must be in the
same logical subsystem on some early
models of DASD supporting FlashCopy.
– The number of target extents must equal
the number of source extents.
X'85' The specified target volume is a
Peer-to-Peer Remote Copy primary or
secondary volume.
HCP296E
X'9C' Cannot complete due to internal hardware
conditions or lack of resources to manage
the relationship.
X'9D' The number of FlashCopy relations exceeds
the maximum allowed.
X'A5' The FlashCopy operation is only valid for full
volumes and does not allow specification of
extents on early models of DASD supporting
FlashCopy.
X'A6' The number of FlashCopy target relations
exceeds the maximum allowed for one or
more of the source tracks.
