It would appear that disk(s) that are part of this volume group are defective (I/O error). There is nothing you can do in HP-UX to correct the problem. Also take a look at the HP-UX syslog.log located in /var/adm.syslog. If these are part of a large disk array, look at the array status and logs. Since diskinfo works, the LUNs are properly mapped to this server so the problem is with the internal array. Talk to your storage adminstrator.
