An I/O error occurred for the specified checkpoint data set.
datasetname is the DDNAME for the checkpoint data set.
nodename is the major node name.
major is the RPLRTNCD hexadecimal return code from VSAM.
minor is the RPLERRCD hexadecimal return code from VSAM.
VTAM® terminates checkpointing for this major node. If nodename is a major node name on a VARY ACT command (with the WARM operand), VTAM stops processing the command.
This is probably a hardware error. Save the system log for problem determination.
