 A permanent I/O error (I/O completion
code other than X'7F') has been detected for a JES2 checkpoint
data set I/O operation. Depending on the point in JES2 processing
where the error occurred, data may have been read                

or written and the error may or may not be catastrophic.
 In
the message text:  member-name
The name of the JES2 member experiencing the I/O error.
n
The number of the checkpoint data set. Is either 1 or 2.
volser
The volume identifier.
dsname
The name of the checkpoint data set.
cc
Specifies the completion code returned (in hexadecimal). It may
be one of the following:  41
(PERMANENT ERROR)
42
(EXTENT VIOLATION)
44
(INTERRUPT CONDITION)
4F
(ERROR RECOVERY FAILURE)
6D
NO PATHS AVAILABLE
cc

hhhh
Specifies the CSW residual byte count in hexadecimal.
sens
Specifies the sense byte 0 returned in the IOB. It may be one
or a combination of the following:  80
Command reject
40
Intervention required
20
Channel bus out parity check
10
Equipment check
08
Data check
04

ssssssss
Complete device specific sense information (set after a unit check).
See the appropriate device document for an explanation of the sense
information.
opwwwwww,wwwwwwww
Specifies the CCW that failed, where op may be one of the
following:  03
(NO-OP)
05
(WRITE DATA)
06

op
(UNKNOWN)

nnnnnnnn
Specifies the checkpoint data set record to which I/O was attempted.
It may be one of the following:  CHECK
LOCK
MASTER
CHANGE-LOG
4K-PAGE
UNKNOWN

System action
 JES2 continues processing while issuing messages
informing the operator of possible recovery actions. If the error
is not severe, JES2 continues processing without operator intervention.
 Note: JES2 issues a $SDUMP to allow examination of the IOB and CCW
packets when $HASP291 is issued for a checkpoint data set I/O error
indicating command reject in IOB sense byte 0.

Operator response
 Notify the system programmer and respond
to subsequent messages as directed.

System programmer response
 Determine the severity and extent
of the error (channel, control unit, device, media) from the channel
status word and sense byte information provided. Determine the appropriate
recovery procedure and respond to subsequent messages to perform recovery.
