    Hi,

    Actually we use older version AIX.

    oslevel -r Output: 4330-11.

    devrsrv command is not found in this version AIX.  This error is reported on 17-Nov & not reporting any error then after for the disk.

    Please suggest if reason for error shall be identified from SENSE DATA. No events is reported in storage logs

    I ran those sense codes through a diagnostic utility and it revealed reservation conflict...implying that the lun is reserved by something else.

     

    What does lsdev -Clhdisk38 shows

    What does lsdev -CF "name parent" | grep hdisk38 show.   What is the parent adapter of that disk? What other devices show from that adapter.

    What does lquerypv -h /dev/hdisk38 0 10 show (this tries to read from the disk)

    When did this issue start.  What is on that disk? What other disks are on the system served from this storage unit?

    How do you know that lun is assigned to that LPAR?
